Epiphyte with hanging branches + *50 m. long, in moss-grown small 

 forest. Leaves 3'5 cm. including hair-like acumen + 5 cm. long by 1'9 cm. 

 broad. Petiole 2 mm. long. Racemes +3 cm. long, including peduncle 

 + 1'4 cm. and pedicels 1*1 cm., both slightly sericeous ; flowers 4 mm., pink. 

 Sepals 2 - 5 mm. long. Petals 4 mm. Stamens 1'5 mm. long ; anthers shorter

 pairs of leaves and the 4-merous pink flowers. 



The leaves were infested with Leptotliyrella sericolece Ramsbottom (p. 04). 



Pyrsonota Ridl. and Mischopleura Wern\mm = Sericolea. In the generic 

 diagnosis of the latter 10 stamens are given, but in one bud of S. ovalifolia 

 examined 15 stamens were seen.
