and endemic. An interesting example of this is offered by the 
genus Dendrochilum in the Philippines, which is composed en- 
tirely of endemic species, if we exclude one or two which have 
been ascribed to the Philippines conjecturally on evidence too 
slight for recognition. 
HABENARIA Willd. 
Habenaria Curranii sp. nov. 
Planta 6 dm alta, foliis paulum infra medium partem caulis 
congestis, lanceolatis, acuminatis. Sepala lateralia lanceolata, 
vel lineari-lanceolata, aristata, sepalum superius simile, lanceo- 
latum, acuminatum, cucullatum. Petala bipartita, lacinia pos- 
terior linearia, lacinia anterior posteriori similis sed longior, 
4.5 cm longa. Labellum usque ad basim tripartitum; laciniae 
laterales media longiores, filiformes ; lacinia media 1.7 cm longa. 
Calcar prope apicem subdilatatum, processus stigmatis promi- 
nentes. 
Plant tall, slender throughout, leaves five or more, narrowly 
lanceolate, acuminate, acute, 7.5 to 11 cm long, 1 to 2 cm wide, 
clustered near the middle of the stem or lower, about 2 dm 
above the roots. Bracts of the stem sheathing, those above the 
leaves acuminate, aristate, about 2 cm long. Raceme slender, 
elongated, smooth, many-flowered (about 20), flowers greenish. 
Bracts of the inflorescence aristate, about equaling the flowers, 
ovary and pedicel about 2 cm long, smooth. Lateral sepals 
spreading, narrowly lanceolate, 3-nerved, acuminate, aristate, 
about 1 cm long, 2 mm wide. Upper sepal similar to but shorter 
than the laterals, 7.5 mm long. Petals bipartite, posterior divi- 
sion (free from the dorsal sepal?) linear, 1 cm long, anterior 
division filiform, 4.5 cm long. Labellum tripartite, lateral divi- 
sions much longer than the middle one, filiform, about U cm 
long (!), middle division broader than the laterals, about 0.5 
mm wide, 1.7 cm long. Stigmatic processes elongated, tapering, 
longer than the anther-canals. Spur stout, somewhat inflated 
near the tip, about 2.4 cm long.

Similar in habit to H. ponerostachys Reichb. f., but unlike that species 
in the size and structure of the flowers. It is also like H. aristulifera 
Reichb. f., but the floral divisions are conspicuously longer in H. Curranii 
Habenaria Delessertiana Kranzl. Gen. et Sp. Orch. 1 : 233. 
Kranzlin cites Cuming’s 2086 as the type of this species, but under 
Habenaria muricata Vidal (H. hystrix Ames) he also cites this number of
