A glabrous epiphytic caulescent herb, stem ascending 10-20 cm. 

 long ; leaves distichous linear unequally bilobed, sheaths verru- 

 cose, 3-5 cm. long, 0'3-0-6 cm. wide ; peduncles axillary filiform 

 1 or more rarely 2flowered ; bracts broadly ovate acute, 0*4 cm. 

 long ; sepals linear lanceolate acuminate or setaceous-acuminate, 

 2-5-3-5 cm. long ; petals very like the sepals but a little shorter ; 

 lip semi-infundibuliform, resembling a shell, setaceous-cuspidate 

 at the apex, 1-1*3 cm. diam., spur widely spreading, filiform, 

 4-5 cm. long ; column rather square ; pollinia 2 ; caudicle and 

 gland not seen. 



Described from one living and several dried specimens. It is 

 one of the most beautiful and delicate of the Angraecums. I have 

 not been able to discover the caudicle and gland in any of the 

 specimens which 1 have examined.
