3E7087940C24FFE8A69EFA80F4CEFAF6.taxon	distribution	Distribution, habitat, and ecology. – Croton chapelieri is known from coastal Antsiranana, Fianarantsoa, Toamasina, and Toliara Provinces. It is sometimes locally frequent in littoral forest and scrub, mostly on white sands, from sea level to 40 m elevation (Fig. 1, 2 A-B).	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.

3E7087940C24FFE8A69EFA80F4CEFAF6.taxon	vernacular_names	Vernacular names. – Croton chapelieri has numerous recorded common names, which include: Fotsiavadika ” (Jacquemin 1267), “ Hazomanitra ” (Louvel 217), “ Sagnira ” (Ludovic 1660), “ Sarihafotra vavy ” (Randrianaivo et al. 1976), “ Sily ” (Service Forestier 7289), “ Tsinjeny ” (Rabevohitra 2024) and “ Tsivoanjo ” (Hoffmann 194). They probably reflect both the morphological variation of the species and its widespread distribution that spans numerous different dialects of the Malagasy language.	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.

3E7087940C24FFE8A69EFA80F4CEFAF6.taxon	biology_ecology	Conservation status. – Croton chapelieri can be locally abundant, but its sandy littoral habitat is very restricted, and it is known so far from seven sites, three in Toliara, one in Antsiranana, one in Fianarantsoa and two in Toamasina provinces. We therefore recommend that it be assessed as “ Near Threatened ” [NT] following the IUCN Red List Categories and Criteria (IUCN, 2012).	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.

3E7087940C24FFE8A69EFA80F4CEFAF6.taxon	discussion	Notes. – Although Leandri (1939) recognized C. chapelieri and even named his “ Groupe Chapelieri ” after it, he characterized the species as being “ incomplètement connue. ” This was presumably due to the poor condition of the type, which consists of a leafy branch with only the naked axis of one inflorescence [no flowers remain, although Baillon (1861) did describe them]. Also, there was no collecting location given. However, we know from Dorr (1997) that Chapelier (1779 - 1806) spent most of his time in Madagascar living near Foulpointe north of Tamatave, and it is quite likely that this is the area where the type of C. chapelieri came from. In the same treatise by Leandri (1939), he described C. louvelii as part of Groupe Chapelieri and recognized that both it and C. chapelieri have the same distinctive foliaceous pistillate calyces. His key simply separated C. louvelii from C. chapelieri as having “ parties jeunes non hirsutes ” vs. “ parties jeunes un peu hirsutes. ” The type locality of C. louvelii is the littoral forest of Tampina, which is farther south of Foulpointe in Toamasina Province. Comparing the two types, they are a very good match, and there are some trichomes on the young growth of C. louvelii that are similar to those on the type of C. chapelieri. These similarities are the justification for our decision to synonymize C. louvelii. Also, because of the lack of flowers on the single type specimen of C. chapelieri, we designate here an epitype from a recent collection (van Ee et al. 925) for which multiple duplicates, photos of live material, and DNA sequence data are available. Leandri (1973) described the first of a series of taxa from the southeastern coast of Madagascar that are also treated here as synonyms of C. chapelieri. His C. aymoninorum Leandri came from the littoral forest of Mandena, along the coast north of Fort Dauphin. Instead of assigning it to one of the groups that he recognized in his earlier treatise (Leandri, 1939), he instead treated C. aymoninorum as part of a bewilderingly diverse array of species whose only character in common was that of their contracted inflorescences. Largely for that reason, we believe, its affinities to C. chapelieri went unnoticed, and later Radcliffe-Smith (2016) described C. daphniphyllum from the same forest that C. aymoninorum came from. Mandena is a relatively small area of sandy littoral forest that has been extensively collected by botanists over many decades, including ourselves, and we are quite confident that only three species of Croton occur there – C. chapelieri, C. cassinoides, and C. trichotomus. Croton chapelieri is morphologically quite variable, particularly in leaf shape and pubescence. The leaves are typically elliptic but vary from lanceolate to obovate. Similarly, the apex can vary from acuminate to rounded, the base can be cuneate or rounded, and the margin can be entire or serrate towards the apex. Extensive collections and our own field studies from coastal areas of southeastern Toliara Province (Mandena, Petriky, and Sainte Luce) show that the types of both C. aymoninorum and C. daphniphyllum correspond to a locally common species found in sandy, littoral forests to the west and north of Fort Dauphin, in the Mahabo area of Fianarantsoa Province, and then in Toamasina Province farther north. In the Sainte Luce and Petriky areas of southeastern Toliara Province, besides the more typical stellate-lepidote form, there are populations in which the shoots, leaves, and inflorescences are villous due to the presence of a porrect central radius to the stellatelepidote trichomes (Fig. 2 C). These forms correspond to what Radcliffe-Smith (2016) described as C. chapelieri var. hirsutus Radcl. - Sm. (from the Petriky forest) and C. rhododendroides Radcl. - Sm. (from the Sainte Luce forests), both of which are included here in synonymy as well. Finally, Radcliffe-Smith (2016) described C. daphniphylloides Radcl. - Sm., differing only slightly from his C. daphniphyllum and whose type comes from Ambila-Lemaitso, which is very close to the Tampina, the type locality of C. louvelii. The other paratype of C. daphniphylloides is from Tampolo, farther north in Toamasina Province and presumably close to the type locality of C. chapelieri itself. The name C. chapelieri var. longepetiolata Radcl. - Sm. is based on a single specimen (Malcomber et al. 2511) from 500 - 750 m elevation in Zahamena National Park in Toamasina Province. It appears to be a fairly typical specimen of C. submetallicus Baill. Beyond the specimens cited below, there are many more specimens of C. chapelieri that we have identified, particularly from the well-collected forests of Petriky, Mandena and Sainte Luce in Toliara Province and in the Mahabo Reserve of Fianarantsoa Province. These have all been entered into the Madagascar Catalogue (2016) with our determination and can be found in the specimen list under Croton chapelieri.	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.

The type collection from Vatomandry was collected at the edge of a lagoon, and the specimens from Mahabo are from moist, somewhat boggy areas within the littoral forest and grassland zone, where they were growing mostly at the edge of patches of shrubs or Ravenala in areas with standing water, Sphagnum, ferns, grasses, and sedges (Fig. 1, 3 A-B).	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.

3E7087940C22FFE5A52EFD72F3AEF882.taxon	conservation	Conservation status. – Besides the type locality near Vatomandry in southeastern Toamasina Province, Croton vatomandrensis is presently known from the forest of Vohibola farther north in Toamasina, and a small area near Mahabo, in Fianarantsoa Province. No collections have been made of it from the type locality near Vatomandry since the type was collected in 1921. Whereas C. chapelieri was locally common in the sandy forests at Mahabo, we saw very few individuals of C. vatomandrensis there. Given the restricted occurrences in just three known localities and the threat of habitat destruction in those sites, we recommend that this species be assessed as “ Endangered ” [EN B 2 ab (ii, iii, iv)], following the IUCN Red List Categories and Criteria (IUCN, 2012).	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar. Candollea 72 (1): 35-44, DOI: 10.15553/c2017v721a5
3E7087940C22FFE5A52EFD72F3AEF882.taxon	discussion	Notes. – Croton vatomandrensis is distinct with its sparsely branched habit and slightly succulent stems, the glabrous leaves and fruits, and the stellate-lepidote indumentum on young shoots that is reddish brown when young but turns pale gray with age (Fig. 3 D). The erect spike-like inflorescences are also characteristic (Fig. 3 G). It is notable that they appear to be dormant for extended periods of time before the onset of flowering. When Leandri (1939) described this species, he placed it in the informal “ Groupe Fothergillifolium ” together with C. fothergillifolius from Mauritius and C. furcellatus Baill. from Madagascar. Although he included all three species in his key to the group, there was no corresponding species entry for C. furcellatus. Instead, he included that species at the end of the article in his list of insufficiently known or doubtful species, mentioning that it might represent an introduction or a mislabeling. Although the type label of C. furcellatus indicates it is a Scott-Elliot collection from Fort Dauphin in southeastern Madagascar, it was actually mislabeled at Paris in a shipment that had been received from Kew (an error documented by Humbert, 1948). The type specimen of C. furcellatus is in reality a New World Croton, C. sonorae Torr., most likely an Edward Palmer collection (Palmer 180) from northern Mexico. Both Leandri’s “ Groupe Fothergillifolium ” and “ Groupe Chapelieri ” were characterized as having staminate flowers with more than 12 stamens, a lack of lepidote scales, two acropetiolar glands (with no other glands on the leaf surface), leaves glabrescent on the abaxial surface, and petals of the pistillate flowers rudimentary or lacking (Leandri, 1939). The only difference in Leandri’s key between the groups was one of leaf blade proportions (blade at least twice as long as wide in Groupe Chapelieri and blade at least half as wide as long in Groupe Fothergillifolium). In a recent molecular study of Western Indian Ocean species of Croton (Haber et al., in press), C. fothergillifolius is part of a highly supported clade of four species confined to the Mascarene island of Mauritius, whereas C. chapelieri and C. vatomandrensis are both embedded within a broader group of Malagasy, African, and Comoro Islands species, and they furthermore form part of the same, albeit poorly supported clade together with C. bracteatus and another undescribed species. This shows at least that C. vatomandrensis does not belong in the same group as C. fothergillifolius, and that the circumscription of Groupe Chapelieri needs to be examined in greater detail to determine whether C. vatomandrensis is actually closely allied to C. chapelieri or not.	en	Kainulainen, Kent, Berry, Paul E., Ee, Benjamin van (2017): Rediscovery of two species of Croton (Euphorbiaceae) from littoral habitats of eastern Madagascar.
