NOTES ON PHILIPPINE ORCHIDS, III. 
47 
The type collection consists of two plants, preserved in the Herbarium 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. CESTICH IS Pfitzer. 
Cestichis Lyonii sp. nov. 
Radices nmltae, fibratae. Pseudobulbi fasciculati, 2 cm longi, com- 
planati, in sicco usque ad 1.5 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, ©rectus. 
Bracteae lineari-lanceolatae, setaceae, elongatae, 1 cm longae. Racemus 
longissimus, densus, usque ad 12 cm longus. Bracteae inflorescentiae 
lanceolatae, acutae, 2-4 mm longae, pedicellum et ovarium excedentes. 
Flores flavidi. Sepalu lateralia oblongi-lanceolata, acuta, valde uninervia, 
4.5 mm longa, 2 mm lata. Sepalum intermedium simile. Petala linearia, 
uninervia, 4 mm longa. Labellum orbiculare subito acuminatum, 5- 
nervium, 4 mm longum, circiter 3 mm latum. Columna exalata, cras- 
siuscula, 2 mm longa. 
Luzon, Benguet Subprovince, Baguio, 155 W. S. Lyon (type in Hb. Ames). 
Mindoro, Mount Inauan, For. Bur. 9959 M. L. Merritt, January 22, 1908, 1,300 
m 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, Pol. Orch. Oberonia 2; 
Ames Orchidaceae 1 : 77. 
This species appears to be very common in northern Luzon. The material from 
which Lindley obtained his original and very brief description was imported 
from Manila by Messrs. Loddiges. From Lindley’s description, in the “Botanical 
Register,” it is quite impossible to identify with any degree of surety plants 
which may prove conspeeific with 0. cylindrica. Furthermore, his remarks in 
“Folia Orchidacea” are inconclusive. In neither work does he refer to foliage, 
although in “Folia Orchidacea” he places O. cylindrica in the same section with 
O. iridifolia, among the acaulescent species which have radical leaves. In order 
to obtain light oh the subject I sent a specimen, representative of material 
which I had 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 
inflorescence only. For a description, supplementary tb Lindley’s, reference 
should be made to my list of Philippine orchids published in the first volume of 
“Orchidaceae.”
