upper part of the very large, deep, stigmatic cavity. Pol- 
linia two, globose, each one slightly furrowed and thus 
divided into a large and a small perfectly joined mass; 
the pollinia are attached to the rostellum by a stipe which 
passes (in a groove) from the apex of the column to the 
rostellum which is about 0.5 mm. below.

The genus Phragmorchis seems to be most closely 
allied to Schoenorchis. It should doubtless be placed be- 
tween Schoenorchis and Sarcanthus in the system pro- 
posed by Schlechter in Notizbl. Bot. Gart. u. Mus. Ber- 
lin-Dahlem 9 (1926) 563-591. 
Phragmorchis may be distinguished from all other 
genera of the Sarcanthinae known to me, by a combin- 
ation of the following characters: a very small (almost 
minute) rostellum; a straight footless or nearly footless 
exalate column; a deep groove from the clinandrium to 
the rostellum in which the stipe of the pollinia lies; a very 
large stigmatic cavity; the lateral lobes of the lip being 
free from the column; the spur or sac with only two very 
thin, inconspicuous calli at the base of the mid-lobe of 
the lip; the terete leaves which are angled (at least when 
dry); and a very short few-flowered inflorescence. 
THREE NEW SPECIES OF ORCHIDS FROM BORNEO 
The orchids described below are among a collection 
sent by the Botanic Gardens, Singapore, Straits Settle- 
ments to the Ames Herbarium for study and determin- 
ation. The specimens were collected by Major J. C. 
Moulton in Borneo. The three species described here 
are of particular interest, but many of the other speci- 
mens are of rare species.
