Sect. I. EUARUNDINA. Raceme simple or sparingly "branched; bracts 

 small, broadly ovate, acute, persistent. Lip very variable but always 

 large, oblong, broad, subentire or with obscure side lobes, a small crisped 

 terminal lobe and 2 or more lamellate nerves at the base.

TROPICAL HIMALAYA, from Nepal eastwards. ASSAM and the KHASIA MTS. to 

 Hunnipore and Chittagong. MALABAR, fid. Wight. DISTRIB. Java. 



Stem 5-7 ft., sometimes as thick as the thumb below. Raceme stout, simple or 

 laxly pauicled bracts % iu., broad, coriaceous, subacute. Lip brighter red than the 

 sepals. Capsule decurved, 2-2| in, Griffith at p. 331 describes the petals and 

 sepals as white, at p. 329 as flesh-cold. Lindley errs in describing the petals as 

 lanceolate, and Wight in giving Ceylon as the locality for his drawing, which is 

 from a specimen in his Herbarium marked " Assam, Griffith."

 Linn. Sue. iii. 23 ; leaves 6-10 by 3 | in., raceme very short, flowers as in 

 bambusi folia, but midlobe of lip very obscure. Walp. Ann. vi. 456. PA.

PEHAK, SINGAPORE and MALACCA; on Mount Ophir, Maingay, &c. (Kew 

 Distrib. 1635, A. speciosa). 



A more slender plant than A. 'bambusifolia, with a shorter raceme ; but I 

 doubt its specific difference. Perhaps the A. speciosa, EL, but the petals are not 

 lanceolate. 



3. A. chinensis, Illume Bijd. 502 ; stem 8-12 in., leaves 4-7 by

SIKKIM HIMALAYA, on the outer hills, J. D. H. KHASIA HILLS ; in grassy 

 places, alt. 3-5000 ft., common, Griffith (Kew Distrib. 5195, 6796), &c. DISTRIB. 

 China. 



Apparently identical with the Chinese plant, and distinguished from A. bambiisi- 

 folia by the small size and yellow on the lip. Lindley s;iys it has only 2 ray^ed 

 lamellae on the lip instead of the 5 of the former plant, but 1 find 5 thickened and 

 lamellate nerves. The raceme is rarely 7-hVl., the flowers extremely variable in size. 

 Griffith doubts its specific difference, but if so, all the Indian species (except sect. 

 Dilochia) should be united, in which I might concur. 



4. A.' minor, Lindl. Gen. Sf Sp. Orchid. 125; stem 8-12 in., leaves 

 2-5 by ^-i in. erect' strict, raceme long peduncled few-fld., sepals and 

 petals as in A. cJihioisis, but smaller. 



CEYLON ; in the Central district, ascending to 1000 ft., not uncommon. 

 This differs from A. cJiinevsis in the shorter suherect strict Kaves that are 

 acuminate or subacute with an apiculus and smaller flowers. Capsule 1-H in.
