Description

Tree 10-12 m tall; young branches dense short-tomentose, closely appressed pilose, or -villous around axillary bud, glabrescent, yellow, orange or orange-red; bark brown to red-brown; lenticels few to numerous, usually minute. Leaves in verticells of 4, but some paired or spirally arranged especially lower down twigs, sessile; petiole to 5(-7) x 1-4 mm, sparsely pilose or glabrous; leaf blade chartaceous to sub-coriaceous, closely appressed-sericeous, pale yellow or grey to yellow-brown, glabrescent, narrow obovate to oblanceolate, occasionally narrowly elliptic or widely obovate, 10-34 x 3-10 cm, base symmetrical, obtuse to acute, less frequently cuneate to ± decurrent, apex acute to rounded, usually acuminate, margin ± revolute; venation conspicuous to obscure, raised both sides, often eucamptodromous at base, brochidodromous further up, midvein plane to sunken above, secondary veins 7-13 pairs, either ascending immediately or straight and parallel before ascending. Inflorescence unbranched or branched, 8.4-31 cm x 1-3 mm, usually with whorls of scale leaves on primary axis (rarely on secondary axes); lateral inflorescences 2-8, at 1-2(-3) nodes, verticillately arranged, 7-30 cm x 0.5-1.5 mm, short orange-brown tomentose to pilose; common bracts 0.5-3 mm long, golden- to orange-brown, tomentose to pilose, or villous; pedicels 4-12(-14) x 0.25-0.4 mm, elongating after flowering, closely appressed sericeous or short tomentose, to pilose, yellow-orange to orange-brown. Flowers 4.5-9 mm long; tepals indument straighter and paler than for pedicels; free part of filaments 1.5-3 mm long, adnate to tepals 1-2(-3) mm from base, anthers oblong, 0.7-1.5 x 0.3-0.7 mm; hypogynous gland 1.5-2.5 mm long, lobed to 0.5-1 mm from top, lobes often acuminate; ovary hairs orange to orange-red villous extending 1-2 mm from base, style 0.2-0.3 mm broad at midlength, ± clavateFruit pedicel 6-12 x 2-4 mm. Fruit subglobose, 3-5 cm diam., apex rounded, smooth, glabrous, almost black when immature, lightening to brown or red-brown; pericarp 2-6 mm thick, outer mesocarp 1-5.5 mm thick, thicker in immature fruit, mid mesocarp 0.5-1.5 mm thick, inner mesocarp present when immature, very thin; seed globose, to 2.7 cm diam.; cotyledons thick, fleshy, pale red-brown.

Notes

Photographs (number 27820) labelled "Types of the Delessert Herbarium" are probably of the true type of Panopsis sessilifolia. The specimen is annotated Leblond 224, dated 1792, with an old label determining it as Roupala sessilifolia.
