Living plants were collected in the mountains of Rizal Prov¬ 
ince, by Novaliches orchid collectors, at medium altitudes. 
Pedicellate ovary cameo pink to almost white; sepals and 
petals white dotted with light mallow pink; middle lobe of the 
labellum phlox purple to magenta; lateral lobes of the labellum 
phlox pink spotted with magenta; the spur magenta. Flower¬ 
ing season from December to February. 
A species often mistaken locally for Anota violacea (Lindl.) 
Schltr. However, the two species are conspicuously differen¬ 
tiated by the floral parts. It differs from Aerides quinquevul- 
nerum Lindl. in being a more slender plant, in the size and color 
of the flowers, and in the structure of the floral parts partic¬ 
ularly the labellum. The species is allied to Aerides Leeanum 
Reichb. f., differing in the shape and details of the labellum.

A typo foliis latioribus sepalis lateralibus saepissimi truncatis 
et floribus paulo majoribus intensius coloratis differt. 
Plant more robust than the species. Leaves 13 to 19 cm long, 
3.5 to 4 cm wide, about 2 mm thick, more distichous, broader 
and more rigid than in the species. Racemes 11 to 19 cm long, 
with the peduncles 26 to 62 cm long. Flowers more intensely 
colored than in the species, flower parts not so spreading as in 
the species, about 10 mm across, 20 to 21 mm long. Pedicel¬ 
late ovary mallow purple, 20 to 22 mm long. Lateral sepals 
bent forward, with the anterior margin slightly involute, sub¬ 
quadrate, truncate, about 7.5 mm long, 6.5 mm wide, 7-nerved.
