 fid., sepals oblong, petals smaller and narrower, side lobes of lip triangular 

 acuminate, midlobe short incurved, column pubescent at the base in front,

 in Trans. Linn. Soc. xxx. 136 (not of Lindl.}. Aerides appendiculatum,

 12 in. ; bracts minute ; pedicels short j flowers ^ in. diam. ; petals and sepals re- 

 flexed, yellow-green ; lip rose-pink, spur 2-celled below the middle by a lamina 

 descending from the base of the midlobe ; dorsal callus very large, lobed, pubescent 

 at the base ; anther short ; pollinia very large, strap broadly triangular -ovate. 

 Very near S. teretifolius of China, but flowers very much smaller and spur longer. 



** Leaves flat or channelled. 



f Stem elongate, scan dent or pendulous. 



4. S. secundus, Griff. Notul. iii. 362 ; Ic. PL Asiat. t. 336 ; stem 

 slender elongate, leaves 4-7 in. narrowly linear-lanceolate acuminate, 

 racemes slender, flowers subsecund, sepals oblong obtuse, petals smaller, 

 side lobes of lip tooth-like, midlobe small ovate acute concave, spur conico- 

 infundibular obtuse gibbous dorsally. Micropera pallida, Lindl. in Wall. 

 Cat. 7321 (in part), (not of Gen. & Sp. Orchid.). 



SILHET, Wallich. UPPER ASSAM, Griffith. 



Leaves \-^ in. broad, rigid, 5-nerved ; sheaths f-1 in., deeply grooved when dry. 

 Racemes shorter than the leaves, peduncle and rachis slender; bracts minute, 

 pedicel with ovary in. ; flowers i in. diam. ; sepals and petals red with white or 

 yellowish margins and central band ; lip rose-cold., very fleshy, spur white with a 

 longitudinal septum, dorsal callus 2-lobed ; column stout, short, rostellum subulate ; 

 anther long-beaked, strap of globose pollinia slender, dilated above, gland minute. 

 Capsule i-f in., ellipsoid or oblong, ribs low. Referred to under S. peninsularis as 

 possibly that plant by Lindley (in Journ. Linn. Soc. iii. 39), but is very different. 

 From a so-named drawing in Herb. Calcutt. this would seem to be the original 

 S. oxyphyllus, of Wallich's mss. ; and that Lindley inadvertently transferred that 

 name to No. 16. 



5. S* peninsularis, Dalz. in Hook. Kew Journ. iii. (1857), 243 ; 

 racemes 1-6 in., flowers deflexed, sepals and smaller petals obovate-oblong
