Nodoa, McClure 8015, January 2, 1922. In thickets along 
roads, altitude 250 meters, the flowers white, fragrant. 
This specimen differs so radically from typical Rhaphiolepis 
indica Lindl. in its nearly glabrous inflorescences and calyces, 
and especially in its very short glabrous bracts and bracteoles 
that I cannot see how it can be referred to Lindley’s species; 
nor does it appear to be referable to any of the described forms 
reduced by Hemsley to R. indica Lindl.

antheris anguste oblongis, 6 mm longis; ovario densissime ferru- 
gineo-villoso. Pedicellis tenuibus, 4 ad 6 cm longis, bracteis 
bracteolisque filiformibus, 3 ad 4 mm. longis. 
Loh-hoe, Moninger 160, May, 1919. In forests. 
A species well characterized by its large white flowers, the 
obovate petals being densely villous externally, its long pedicels, 
filiform bracteoles, and cordate castaneous leaves. The calyx 
tubes are very slender, and the sepals are reflexed in anthesis. 
The buds are oblong-ellipsoid, 1 cm long or less, and obtuse. 
It apparently belongs in the group with Bauhinia polystachya 
Gagnep.
