NOTES ON PHILIPPINE ORCHIDS, III. 47 
The type collection consists of two plants, preserved in the Herharium of the 
Bureau of Science. Unfortunately both plants are in fruit so that my descrip- 
tion is based on terminal flowers. The flowers in dried specimens are yellowish. 
161. CESTICHIS Pfitzer. 
Cestichis Lyonif sp. nov. 
Radices inultae, fibratae. Pseudohulhi fasciculati, 2 cm longi, com- 
planati, in sicco usque ad l.o cm in. crassitudine, rugosi. Folia bina, 
oblongi-lanceolata^ acuta^ utrinque glabra, 6.5-8.5 cm longa, 1-1.5 cm 
lata, coriacea^ in petiolos desinentia. Petiolus brevis, 5 mm longus. Ped- 
unculus terminalis, bialatus, foliis longior, usque ad 23 cm longus, erectus. 
Bradeac lineari-lanceolatae, setaceae, elongatae, 1 cm longae. Racemm 
longissimus, dpnsus, usque ad 12 cm longus. Bradcae inflorcscentiae 
lanceolatae, acutae, 2—4 mm longae, pedicellum et ovarium excedentes. 
Flores flavidi. Sepala lateralia oblongi-lanceolata, acuta, valde uninervia, 
4.5 mm longa, 2 mm lata. Sepalum intermedium simile. Petola lincaria, 
uninervia, 4 mm longa. LabeUuni orbiculare subito acuminatum, 5- 
nervium, 4 mm longum, circiter 3 mm latum. Cohimna exalata, eras- 
r 
siuscula, 2 mm longa. 
Luzon, Benguet Subprovince, Baguio, Jo5 W. S. Lyon (type in lib. Ames). 
MiNDOEO, JMount Inauan, For. Bur. 9050 M. L. Merritt, January 22, 1908, 1,300 
ni altitude (single specimen in Hb. Bureau of Science). 
The labellum is orbicular and at the apex abruptly contracted into an obtuse 
tip. The pseudobulbs in dried specimens have the appearance of having been 
strongly compressed or flattened when fresh. 
162. OBERONIA Lindl. 
Oberonia cylindrica Lindl. Bot. Reg. 1840, Misc. 20, Fob Oreh. Oberonia 2; 
Ames Orchidaccae 1 : 77. 
This species appears to be very common in nortliern Luzon. The material from 
whicli Lindley obtained his original and very brief description was imported 
from Manila by Messrs. Loddiges. From Lindley*s description, in the "Botanical 
Roister," it is quite impossible to identify with any degree of surety plants 
which may prove conspecific with 0. cylindrica. Furthermore, his remarks in 
"Folia Orcliidacea" are inconclusive. In neither work does he refer to foliage, 
although in "Folia Orchidacea" he places 0. cylindrica in the same section with 
0. iridifoliaj among the acaulescent species which have radical leaves. In order 
to obtain light on the subject I sent a specimen, representative of material 
which I bad identified with Lindley*s species, to Kew, where it was carefully 
compared with the type. This comparison verified my conclusions and also 
revealed the fact that Lindley's specimen is destitute of foliage, consisting of the 
infiurescence only. For a description, supplementary to Lindley's, reference \ 
should be made to my list of Philippine orchids published in the first volume of 
"Orchidaccae."
