78826 Quisumbing, December 28, 1929. The living plants were 
collected on trees in mangrove swamps in Aloneros, Tayabas 
Province, and flowered from October to March. The plants suc¬ 
ceed well when nailed on adobe fences, using staples to hold 
the stems. 
This dwarf variety of Renanthera storiei differs radically from 
the species in its small stature, small leaves and flowers, and 
the narrower broadly truncated lateral lobes of the labellum. 
Although the flowers in the variety here proposed are smaller 
than in the type, it is noteworthy that intergrading forms may 
appear. In the herbarium of Oakes Ames there is a specimen, 
A. Loher 6000, collected in Rizal Province, with flowers that 
are equal in size to the largest flowers of var. philippinensis 
with leaves up to 1.5 dm long by 3.8 cm wide. This specimen 
is clearly referable to var. philippinensis.
