COLLECTED IN DUTCH NEW GUINEA. 159 
P. papuana; (2) in the thick, lanceolate, short leaves of the fertile branches; (3) in the 
absence, as far as a fairly good series of specimens shows, of the slender whip-like fertile 
branches so characteristic of this species. The seed is quite globose, without any point, 
and the male-flower scales are more ovate and thicker. 
Although specimens of Podocarpus cupressinus, collected by Haviland on Mt. Kina- 
balu at 11,000 ft. altitude, differ distinctly from typieal forms in the much condensed 
stiffer leaves, and seem to a certain extent to suggest a connecting-link between these 
two species, yet I think that the New Guinea plant must be considered specifically 
distinct.

rotundata. 
Camps X to XI, 6700 to 8300 ft. 
Perhaps most nearly allied to M. hydrophila, J. J. Sm., but with very short teeth to 
the rounder lip, longer auricles, and narrower petals and sepals, whilst the colour 
appears to have been yellow or green, and not purple. 
MICROSTYLIS ACUMINATA, Ridl., sp. nov. 
Caulis succulentus, 10 cm. longus. Folia 3-4, elliptica, ovata, longe acuminata, acuta, 
basi rotundata, ad 16 cm. longa, 4 cm. lata, petiolis 4 cm. longis latis vaginantibus. 
Racemus circiter 20 cm. longus, ad medium nudus, floribus multis dissitis. Bractee 
lineares, acuminate, 1:1 cm. longs, angustissime, deflexe. Pedicelli filiformes, 
1 em. longi. Sepala lineari-oblonga, obtusa, angusta, 4 mm. longa. Petala 
linearia, obtusa, breviora, angustiora, dimidio sepali zequilata. Labellum sub- 
quadratum, apice cuneatum, cuspidatum, cuspide longiusculo minute bifido, 
auriculis longis acuminatis faleatis. Columna curva, longiuscula, stelidiis brevibus 
latis oblongis rotundatis. 
Camp VIa, 3100 ft. 
The lip is rather remarkable for its quadrate form, suddenly sharply cuneate or 
triangular at the tip, ending in a narrow linear bifid cusp. The column is rather longer 
than is usually the case in the genus, and curved.
