THE GENUS ERIA IN THE PHILIPPINE ISLANDS.

a natural group which may be conveniently placed apart from others. 
The -flowers , with the exception of E. bambusifolia, are very small and 
densely arranged.” Lindley, l. c. 
This section is perhaps not strictly separable from § Hymeneria, to which, 
indeed, Hooker f., for the Indian flora, joins it; but in the Philippines the 
division is a convenient one, since it quickly indicates the general nature of the 
species embraced, which in these Islands are relatively numerous. 
E. polyura Lindley Bot. Reg. (1841) Misc. 55; Ames Orchidaceae 1 (1905) 
95; 2 (1908) 196. 
“Caule elongato folioso, foliis lanceolatis acutis patentibus striatis, 
spicis oppositifoliis multifloris nutantibus foliis aequalibus v. brevioribus, 
bracteis ovario cluplo brevioribus adpressis, sepalis petalisque ovatis acutis 
erectis laevibus, labello cordato ovato acuto basi bicarinato.” Lindley, 1. c. 
The type in Lindley’s herbarium is labeled “Loddiges June 1841.” It was 
originally from the Philippines. It consists of two racemes merely. The accom- 
panying camera lucida drawing (fig. 2, below) represents a rather poor, but 
sufficiently serviceable flower from one of these racemes. The dotted lines restore 
the true outline of shriveled or defective parts. On the same sheet with the 
type is a Cuming specimen (for which Mr. Rolfe suggests the number 2128, the 
type number of E. ringens Reiclib. f. ) from the Philippines, marked “E. polyura” 
in Lindley’s hand, which in reality is a very different plant indeed. The flowers 
have no resemblance to those of E. polyura — the lip is trilobed, the perianth- 
segments very narrow and acuminate — nor do the stem and its sheaths partic- 
ularly recall those of this species. 
Luzon, Province of Tayabas, Mount Banajao, Elmer 1393, May, 1906, epiphytic, 
in open ravines at 600 m altitude: Province of Cagayan, For. Bur. 11320 Elemme, 
April, 1908. 
E. Copelandii sp. nov. 
E. Hutchinsonianae affinis. Sympodium productum. Caulis in sicco 
2-4 mm in diametro, vaginis laxis instructus. Folia prope apices caulium 
conferta, in caule florigero 5, lanceolata, acuta, 9-13 cm longa, 7-12 mm 
lata. Inflorescentiae 2, plus minus 7 cm longae, pedunculo plus minus 
1 cm longo, racemo dense plurifloro, plus minus 1 cm in diametro, bracteis 
ovatis vix 2 mm longis. Flores parvi, sessiles. Ovarium pubescens, 1-2 
mm longum. Sepala 3-4 mm longa; dor sale ellipticum, concavum; 
lateralia impariter ovata obtusa, 2.5 mm lata. Petala oblonga vel ovata, 
obtusa, concava, plus minus 3 mm longa. Labellum integrum, saccatum, 
explanatum semiorbiculare, vix 3 mm longum. Columna crassa, 1 mm 
alta; pes aequilongus. (Fig. 3.) - 
The small globose flowers with entire saccate or scoop-like smooth-margined 
lip are distinctive. 
Mindanao, District of Davao, Mount Apo, Copeland 11/23 (type, part in 
Manila, part in herb. Ames), epiphytic, flowers rose-colored, with faint odor. 
For. Bur. 1/600 Mearns & Hutchinson, collected at an altitude of 2,800 m on 
Mount Malindang, Province of Misamis, Mindanao, May, 1906, has leaves and 
inflorescence shorter than in the type, but the floral structure is the same; For. 
Bur. 1/596 from the same locality, the “flowers yellow,” specimens in fruit, may 
be the same.
