Paul, O. K., Conn, B. J. & Henwood, M. J., 2024, Taxonomic review of Polyosma (Escalloniaceae) in Papuasia, Blumea 69, pp. 54-88 : 62-63

Polyosma ilicifolia Blume — Fig. 3

Polyosma ilicifolia Blume (1826) 658. — Lectotype (designated here): C.L. Blume s.n. (lecto L [ L 0035086 ], Indonesia). — Likely syntype: C.L. Blume s.n. ([ L 0035083 ]), Indonesia, Java (= Jawa), without date.

Polyosma serrulata Blume (1826) 659 (‘ serrulatum ’). — Lectotype (designated here): C.L. Blume s.n. (lecto L [ L 0035088 ], middle left flowering specimen; isolecto L [ L 0035088 ] other, partially fragmented, specimens), Indonesia, Java (= Jawa), without date.

Lectotypification — 1. As listed above, Hutchinson (1967) designated P. ilicifolia as type of Polyosma . The lectotypification presented here formally confirms the type status of the collections by Carl L. Blume on sheets L 35086 and L 35083 as held at Naturalis Biodiversity Center (L).

2. In the protologue of P. ilicifolia , additional habitat information is provided, namely “Crecit: in cacumine montium a torum Javae insulae” that was not included on the collection label. The morphology of the herbarium material (L 0035086) is here regarded as in agreement with the brief description provided by Blume (1826: 659). He noted that this species had a long flowering period (namely “Floret: omni tempore”). The two collections on the L 0035086 are both flowering, and this sheet was annotated (confirmed) by Georg Schulze-Menz in 1967 as ‘lectotype’ material. The lower specimen on L 0035086 is partially fragmented.

3. The other Blume collection of P. ilicifolia (L 0035083), incorrectly annotated by an unknown hand as ‘Holotype’, was collected from “Archipel. ins. (printed) Pondok Tenge (handwritten: presumably Pondok Tengah: Middle Hut).” This collection is regarded as a probable syntype and was possibly collected from Taman Nasional Gunung Gede Pangrango, Jawa, Indonesia, as was the synonym P. serrulata (see below).

4. In the protologue of P. serrulata, Blume (1826: 659) provided additional habitat and locality information, namely “Crecit: in sylvis montium Gede et Pangurango (= Taman Nasional Gunung Gede Pangrango, Jawa, Indonesia).”

5. Blume (1851) circumscribed several varieties within P. ilicifolia . However, the taxonomic status of the morphological variation within this species has not been undertaken in this study.
