NOTES ON PHILIPPINE ORCHIDS, IV.

the same collection without any allusion to a mixture having been made in the 
distribution of Cuming's specimens. In my studies of the material collected 
for the Bureau of Science I have examined two series of specimens which 
are clearly referable to H. Delesser liana, being chiefly characterized by the 
linear petals, protuberant in part at the base, by the aristate sepals, and 
by the middle lobe of the labellum being about one-fourth longer than the 
lateral lobes. Another characteristic is the crowding of the oblong-lanceo- 
late leaves near the middle of the stem. 
All of the material distributed as 2086 of Cuming's collections which 
I have examined is referable to Habenaria hystrix, and as //. muricata 
Vidal this number is listed in "Phanerogamae Cumingianae Philippinarum." 
{H, muricata is a synonym of H, hystrix). 
Kranzlin cites "Calananz?" as the habitat of H. Delessertiana, The 
material from Luzon which I have examined was collected at Calauan 
(written on the field label as Calauang). May not the localities in question 
be identical, Kranzlin's "Calananz?" being the same as Calauang?*

Tuberoids fleshy (3 ?). Plants 1.4 to 3.6 dm tall, strict, few- 
leaved, in leafage somewhat resembling H, clavellata (Michx.) 
Spreng. Lowermost leaf elliptic-oblong, obtuse, 4 to 7 cm long, 
1.3 to 2 cm wide, much longer than those above it, which are 
bract-like and about 4 in number. Upper leaves linear, acute, 
the uppermost one about 1 cm long, linear, acute. Floral bracts 
linear-lanceolate, acute, lower ones exceeding the flowers. 
Raceme 4.7 cm long, many-flowered, flowers pale-green. Lateral 
sepals lanceolate or ovate-lanceolate, subfalcate, obtuse, 3.5 mm 
long, about 2 mm wide near the base. Upper sepal elliptic, 
obtuse, 3 mm long. Petals simple, oblong, obtuse, 3 mm long, 
1.25 mm wide. Labellum 4 mm long, 1 mm wide, simple, fleshy, 
linear, tapering toward the tip, with a fleshy retrorse callus or 
* "Calananz" is unquestionably a misprint for Calauan, or Calauang as it 
is frequently spelled. Cuming collected in Calauan from the end of Sep- 
tember to the 15th of December, 1836, according to a letter written by 
him from Manila Dec. 24, 1836, to Sir W. J. Hooker, now preserved in 
Hooker's correspondence at Kew. There is no town by the name of 
Calananz in the Philippines. E. D- M.
