THE GENUS ERIA IN THE PHILIPPINE ISLANDS.

retrofle xa (scarcely distinguishable from the other perianth-segments) would be 
wholly anomalous in the alliance. Ill reality, the lip, compared with the other 
segments, is very small. The following are approximately the dimensions of the 
parts of the flower examined by me: sepals 8-8.6 mm long, 2 mm broad; petals 
6.4 mm long, 1.7 mm broad; lip 3.4 mm long, 2 mm broad. The lip is thick and 
apparently callose on the sides near the base. The specimen, accompanied by 
the usual Cuming label but without number, consists of a single stem (about 1 
cm in diameter near the top, in the dry state) bearing up and down its sides 
5 inflorescences, the longest about 9 cm long and near the summit two leaves, 
the largest about 17 cm long, and 1.8 cm wide.

“Aff. Eriae pubescenti Wight, glabra, bracteis ovatis aeutis, labelli 
ungue brevissimo, lamina oblonga acuminata basi rotundata, gynostemii 
androclinio utrinque semiovato brachiato, angulis anticis medio omnino 
muticis. Caulis carnosus bulbosus (cylindraceus ? planus ?), siccus 
dimidium pollicem latus. Folia oblongoligulata basi cuneata, apice in- 
aequali acuta, tres quatuorve pollices longa, unum pollicem lata. Spicae

tresve lineas longae apiculatae reflexae ovariis pedicellatis subaequales.

“Pseudobulbs rather stout, cylindrical from a stout rhizome, 7-10 
cm long, about 5 mm thick, 2-3-leaved at the summit. Leaves linear- 
lanceolate, about 12 cm long, about 1.5 cm wide, acuminate, acute. 
Peduncle short, about 4 cm long, breaking forth from the upper part of 
the pseudobulbs. Bracts lanceolate, acute. Flowers white. Lateral 
sepals linear-lanceolate, acute, about 6-7 mm long, 1.5 mm wide at base. 
Upper sepal linear-lanceolate, about equal to the laterals. Petals narrowly 
lanceolate, acute, about 6.5 mm long, 1.5 mm wide, 3-nerved, acute. 
Labellum lanceolate, ecallose, smooth, 4 mm long, 1.5 mm wide at base.” 
This species very much resembles Eria retroflexa Lindl.

The type in Lindley’s herbarium at Kew is an unnumbered Cuming specimen 
from the Philippines, consisting of three leaves and one inflorescence. There is a 
drawing of the lip by Lindley showing the two short carinate ealli very near
