C9C86470474C498D358951603583F597.taxon	discussion	Discussion. A comparison of the material has shown that Senecio moqueguensis is most similar to Senecio pucapampaensis and Senecio tassaensis sp. nov. Together with Senecio evacoides, Senecio expansus, Senecio repens and Senecio humillimus, it forms a coherent morphological and geographical group within Senecio subser. Caespitosi which occurs from central Peru to northwest Argentina and is characterized by the presence of trichomes on stems, leaves and involucres. Senecio moqueguensis can be distinguished from Senecio pucapampaensis by the dense caespitose mat habit, leaves, calycular bracts, corolla color, involucres and achene morphology as summarised in Table 1. Senecio moqueguensis can be distinguished from Senecio evacoides, Senecio expansus and Senecio repens by the habit, density of trichomes, leaf shape and length, as well as by the calycular bracts and phyllary length and form.	en	Tubee, Daniel B.

F151825ED50776CE6DE088C2765542CC.taxon	etymology	Etymology. This Senecio is named after Karle Sykora, a well-known Dutch vegetation scientist who was my mentor in phytosociology.	en	Tubee, Daniel B. Montesinos (2014): Three new caespitose species of Senecio (Asteraceae, Senecioneae) from South Peru. PhytoKeys 39: 1-17, DOI: http://dx.doi.org/10.3897/phytokeys.39.7668, URL: http://dx.doi.org/10.3897/phytokeys.39.7668
F151825ED50776CE6DE088C2765542CC.taxon	discussion	Discussion. Senecio sykorae appears to be closely related to Senecio gamolepis which grows at higher elevations but approaches the known range of Senecio sykorae within a few hundred metres. While Senecio gamolepis is generally distinctive in the genus for its large size, attaining widths of up to 1 meter in diameter, and for its larger, capitulate form, Senecio sykorae is a smaller plant, of about 4 - 6 cm wide and has shorter corolla, less than 9 mm long. Senecio sykorae is also distinctive in that it has 12 - 14 phyllaries per capitulum instead of 7 - 9 phyllaries in Senecio gamolepis. Likely the leaves of Senecio sykorae are distinctive in that they are obovate-spathulate vs. linear-lanceolate. Also, the achenes in Senecio sykorae are larger (1.5 - 2 mm long) vs. 1 - 1.3 mm long in Senecio gamolepis. Senecio sykorae also differs from Senecio algens by the leaf and capitula length (shorter in Senecio sykorae), and from both species by the corolla colour (white vs. yellow). Less similarity is found in Senecio algens, Senecio humillimus, Senecio trifurcifolius, Senecio pucapampaensis and Senecio evacoides, and from which Senecio sykorae can be distinguished on the basis of its habit, trichomes, leaf shape and length, calycular bracts and phyllary length and shape as summarized in Table 1.	en	Tubee, Daniel B.

D1F3ACFBED6279201ECCE0F742C45B61.taxon	etymology	Etymology.

D1F3ACFBED6279201ECCE0F742C45B61.taxon	discussion	Discussion. Senecio tassaensis appears to be closely related to Senecio moqueguensis which grows at the same elevational range but approaches the known range of Senecio tassaensis within a few hundred metres. Senecio moqueguensis is generally distinctive in the series for its larger size, attaining dense ground mats, and for its yellow corolla. Senecio tassaensis has 12 - 16 phyllaries (vs. 9 - 12), an involucre length of 6 - 8 mm and achene length of 1 - 1.2 mm, being much shorter than in Senecio moqueguensis. Senecio tassaensis is relatively a very rare species with an estimated 100 individuals known. It is less similar to Senecio pucapampaensis, Senecio evacoides, Senecio expansus and Senecio repens, and can be distinguished on the basis of the habit, trichomes, leaf shape and length, calycular bracts and phyllaries length and shape as summarized in Table 1.	en	Tubee, Daniel B.
