in 8.E. New Guinea (Engl. Bot. Jahrb. liv. (1916) 100). It differs in the 
smaller leaves with much shorter tomentum underneath, the few-flowered 
racemes, and the truncate to 3-lobed petals.

umbellatis, pedicellis gracilibus fultis. Bractee lanceolate, acuminate. Sepala 4, 
lanceolata, acuta, extus sericea, carinata. Petala’ 4, cuneato-obovata, apice truncata 
et brevissime trilobata, basi ciliata. Stamina 1-2, puberula. Discus 5-lobatus.

Epiphyte with hanging branches +°50 m. long, in moss-grown small 
forest. Leaves 3°5 em. including hair-like acumen +5 em. long by 19 cm. 
broad. Petiole 2 mm. long. Racemes +3 em. long, including peduncle 
+1:4 em. and pedicels 1:1 cm., both slightly sericeous ; flowers 4 mm., pink. 
Sepals 2°5 mm. long. Petals 4mm. Stamens 1°5 mm. long; anthers shorter 
than the filaments, with apical dehiscence. Ovary and style +3 mm. long. 
This delicate little plant is, so far, distinct in Sericolea in the more remote 
pairs of leaves and the 4-merous pink flowers. 
The leaves were infested with Leptothyrella sericolee Ramsbottom (p. 64). 
Pyrsonota Ridl. and Mischopleura Wernham=Sericolea. In the generic 
diagnosis of the latter 10 stamens are given, but in one bud of S. ovalifolia 
examined 15 stamens were seen.
