S. gracilis,. Rolfe in Herb. Kew. 



Spathoglottis gracilis belongs to a small group of species, 

 of which the type, if the first described member of it may 

 be so considered, is the Malayan (Mount Ophir) S. aurea, 

 Lindl. (in Paxt. Fl. Garden, vol. i. p. 16, and Joiirn, Hurt. 

 Soc. vol. v. p. 34). The other members of the group are 

 three, S. Kimballiana, Hort. Sander, and S. Wrayi (Fl. 

 Brit. hid. vol. v. p. 813, and Hoolc, Ic. PI. t. 2086). Of 

 these S. aurea has the middle of the lip very narrow, 

 moderately dilated at the tip, and ending in a narrow or 

 dilated acute point, and the side lobes are long and 

 narrow; it inhabits Borneo and the Philippine Islds., as 

 well as Mount Ophir. 8. Kimballiana is a larger plant 

 than gracilis, with larger flowers; the sepals are pale 

 brown dorsally, and the midlobe of the lip is much broader 

 and obovate-spathulate ; it is well figured in the Gardener's 

 Chronicle for 1888, vol. ii. p. 93, fig. 9 (repeated in 

 " Veitch's Manual of Orchids," pt. vi. p. 6), and described 

 by Reichenbach as a variety of aurea. Lastly, S. Wrayi, a 

 native of Perak, in the Malayan Peninsula, has the large 

 flowers of S. Kimballiana, short side lobes of the lip, its 

 auricles at the base of the side lobes are glabrous, and the 

 middle of the lip is narrowly spathulate. Considering the 

 characters of the above three plants, it may well be 



July 1st, 1881.
