Native names: Tayabac, bayo-u (Bataan); buracan (Mindoro). 
Known only from Luzon and Mindoro, and a most striking species, growing 
usually in humid forests, ravines, etc., extending from slightly above sea level 
(Laguna, Mindoro), to an altitude of 1,000 m (Mount Mariveles, Bataan). The 
long, pendent, many-flowered racemes exceed 1 m in length, and the flowers are 
variously described as greenish-blue, nile-green, green, and verdigris; they are a 
very peculiar pallid greenish or bluish-green shade difficult to describe. Dried 
flowers appear as though they were tinged with purple, although in reality there 
is no trace of purple in the fresh flowers. The original description calls for 
reddish or purplish flowers, but as indicated' by Gray, there were no' notes with 
the specimen, and the color was probably estimated from the dried specimens. 
Fully grown flowers vary from 4 to 5 or 6 cm in length, or, if the keel be straight- 
ened out, sometimes 7 cm long. Doctor Perkins has described the flowers of 8. 
loarburgii as 8.5 cm long, but 1 have seen none as large as this, and the measure- 
ment may be due to a typographical error. I can not otherwise distinguish the 
latter species from 8. macrobotrys. I have examined the type of S', macrobotrys, 
but not that of 8. warburgii.

Apparently very closely allied to the preceding, and perhaps not specifically 
distinct; my material of 8. zschokkei is so poor that it is difficult to determine 
the exact differences between it an 8. elmeri. The flowers are described as having
