Quisumbing, February 9, 1934. 
The plant was originally collected by a friend of Doctor Rotor 
from a tree along the road between Baler, Tayabas Province, 
and Cabanatuan, Nueva Ecija Province, Luzon. 
This variety resembles var. immaculata Ames and Quis. in 
the complete absence of bars or maculations on the flowers, but 
differs in the ox-blood red petals and sepals and Vandyke red 
middle lobe of the labellum. 
This variety is dedicated to Dr. A. B. Rotor, a lover of or¬ 
chids.

Vanda Guiberti Lindl. apud Linden and Reichb. f. in synon. 
The present species, which is well figured in Xenia Orch. 
1. c., appears to be referable to the genus Trichoglottis as now 
interpreted, while the concept Cleisostoma Bl. is no longer gen¬ 
erally upheld by orchidologists. 
Moreover, Trichoglottis Guibertii is certainly allied to T. lu- 
zonensis Ames, both vegetatively and florally. On the other 
hand, the name Staurochilus was founded by Ridley on Tricho¬ 
glottis fasciata Reichb. f. which had previously been referred by 
Bentham, apparently with logic, to Reichenbach’s genus Staurop- 
sis. 
Such species as Trichoglottis Guibertii, T. luzonensis, T. Daw- 
soniana, T. fasciata, etc., certainly differ from the original con¬ 
ception of Trichoglottis in having large flowers with scarcely 
developed spur, and in having the inflorescences (more or less 
elongate) either loosely racemose or paniculate. 
It seems highly probable that orchidologists will eventually be 
forced to agree with J. J. Smith, in referring to the genus 
Trichoglottis all these allied and intergrading species.
