THE GENUS ERIA IN THE PHILIPPINE ISLANDS. 203 



a natural group which may he conveniently placed apart from others. 

 The flowers, with the exception of E. bambusifolia, are very small and 

 densely arranged." Lindley, I. c. 



This section is perhaps not strictly separable from § Humowria, 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) 

 05; 2 (1!108) 196. 



"Caule clongato folioso, foliis laneeolatis acutis patentibus striatis, 

 spicis oppositifoliis multifloris nutantibus foliis aequalibus v. brevioribus, 

 bracleis ovario duplo 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. ringent Reichb. f.) from the Philippines, marked "E. polijura" 

 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.

 in open ravines at 600 m altitude: Province of Cagavan, For. Bur. 11820 Klemme,

E. Copelandii sp. now 



E. Hutchinsonianae affinis. Sympodium productuin. Caulis in sicco 

 2-4 mm in diametro, vaginis laxis instructus. Folia prope apices caulhim 

 conferta, in caule florigero 5, lanceolata, acuta, 9-13 cm longa. 7-12 mm 

 lata. Inflorcscentiae 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; dorsale ellipticum. concavum; 

 lateralia impariter ovata obtusa, 2.5 mm lata. PelaJa 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.
