Oirrhopetalum. 



C. Thouarsii [Zi/id/.). — A pretty-flowered species, of some- 

 what robust growth. The smooth pseudo-bulbs are produced 

 from a creeping rhizome, or stem, and bear a single oblong, 

 blunt, dark green, leathery leaf. The flowers are produced in 

 umbels, on the apex of the slender scape ; the long, strap- 

 shaped sepals are of a tawny orange colour, whilst the remainder 

 of the flowers are yellow, dotted with red. It blossoms during 

 the summer months. Native of the Mascarene Isles, 1836. (B. M., 

 t- 4237-) 



CLEISOSTOMA. 



Epiph_\-tal Orchids, of the tribe Vaiidccr. Flower.s .small, 

 fleshy, with a pouched lip, and distinguished from those 

 of Saa-ol(7bii{?n in ha\-ing the orifice of the pouch closed 

 by a large projecting tooth. It is this characteristic that 

 has given rise to Blame's generic name — from kleio, to 

 close, and stoma, a mouth. Leaves leathery, narrow. Roots 

 very long and tough. Though about forty species belong 

 to this genus, yet only a few are in cultivation, and those 

 are principally confined to botanic gardens. The cultural 

 requirements are the same as for Aerides. 



C. ringens (Rchh. /.). — This is a small species with oblong, 

 emarginate leaves, 3in. to 4in. long, and liin. f^road. The 

 flowers are borne on a few-flowered raceme. They are yellowish, 

 with the middle lobe purple, and an orange spot on the side 

 lobes. The middle lobe of the lip is oblong, and faintly warted, 

 and with a large tubercle under the column. The spur is very 

 large, broad, cylindrical, emarginate at the apex. Philippines, 1888. 



COCHLIODA. 



About ten species of cool-house, evergreen, epiphytal 

 Orchids, of the tribe VandccF, go to make up the 

 genus Cochlioda (Lindl.). The name is derived from 

 kochlion, a little shell, and is in reference to the curiously- 

 shaped callus. They are natives of the Andes. Flowers 

 often red, disposed in loose racemes, pedicellate ; sepals 

 equal, spreading, free, or the lateral ones more or less 

 connate ; petals nearly similar ; claw of the lip erect, 

 the lamina spreading, the lateral lobes round and often 

 reflexed, the middle ones narrow, entire or emarginate, 

 not exceeding the sepals ; column erect, often slightly
