 Canoe Camp, 150 ft., and Camp I, 700 ft. 



A charming plant, allied to 31. Warcqnissce, Scbleclit., but the lip is neither reniform 

 nor toothed, and the auricles are blunt and incurved. The foliage is described by Kloss as 

 dark green and light green or purple-brown and reddish green, and the flowers as deep 

 yellow and crimson, or green to yellow to dull crimson. The leaves show when dry a paler 

 broad bar up the centre. In habit it somewhat resembles M. inici'antha, Hook, fil., of 

 the Malay Peninsula, and in the form of the flower M. ccdophylla, Reichb., of Siam. 



MiCROSTYLIS ATRO-BRACHIATA, Ridl., Sp. UOV. 



Caulis 4 cm. lougus. Folia 4, lanceolata, acuta, basi breviter cuneata, viridia, 

 insequalia, obliqua, 5-nervia, marginibus crispis, 5 cm. longa, 1*5 cm. lata vel 

 minora, petiolo li cm. longo. Racemiis gracilis, 28 cm. longus, ad medium nudus. 

 Flores parvi, approximati. Bractece lanceolatse, acuminatse, augustissimse, defiexae, 

 3 mm. longae vel minores. PecUcelli brevissimi, 1 mm. longi. Sepalum posticum 

 oblongo-lauceolatum, obtusum, lateralia ovata, obtusa, latiora, 2 mm. longa. Petala 

 lineari-oblonga, obtusa, augustiora. Labellum hastatum, integrum, acutum, 2 mm. 

 longum, auriculis triangularibus excurvis. Colunma cylindrica, erecta, longa, pallida, 

 stelidiis niagnis atro-viridibus oblongo-ellipticis deiiexis. Anthera minuta, lanceo- 

 lata, obtusa. Rostellum erectum, lanceolatum, oljtusum, sequilongam, virescens. 

 Camp VI a, 3100 ft. 



Allied to 31. tubulosa, J. J. Sm., it is one of a small group in which the column is 

 unusually tall and slender, the stelidia deep blackish green and veiy conspicuous, the 

 aather small, and the rostellum large and nearly or quite as tall. Excej)t for the fact 

 that there are sjiecies of the genus known which coniiect these long-columned species 

 with the typical forms witli the short column, one would certainly distinguish these 

 generically. The column and anther are pale yellow, or perhaps white, the stelidia of 

 a deep blackish green, elliptic and rounded, at tlie top, and hanging down ; the rostellum, 

 long, conspicuous and narrow, is also a very remarkable feature. 



MiCROSTYLIS (§ COMMELYNOIDE^) CIRCEA, PJdl., sp. nov.
