Nat. Herb. 102 Quisumbing, March 9, 1934. This is the second 
time that this variety has come to the attention of the junior 
author. The first instance was a plant belonging to Mrs. Ste¬ 
wart, collected by her near Baguio in March, 1926. The second 
plant, the subject of this description, was originally collected 
from the mountains of Rizal Province and was found mixed 
with typical Dendrobium anosmum. 
This is one of the purest white dendrobes known, and is 
endemic to the Philippines.

Perigonio candido, labelli disco ac ungue purpureis. 
A very striking novelty. The flowers are clear white. The disc of 
the lip bears two beautiful purplish blotches, and its base is of the same 
colour. For this beautiful thing we have to thank Messrs. Veitch, who 
obtained it through their late excellent collector, Mr. Hutton, from the 
Malayan Archipelago. 
In habit and general features similar to the species. The 
stems are comparatively shorter and more slender. The flowers 
are beautiful, showy, slightly fragrant, and about 8.5 cm across. 
They resemble those of the former variety in being pure white 
throughout but have the throat of the labellum dark purple.
