has a creeping rliizoma, with distant slender pseudo-bulbs, 

 each tipped by a single leaf, and cream-coloured delicate 

 flowers, resembling those of some Maxillarias in form. The 

 genus is distinguished from Maxillaria by the brown sepals 

 not being oblique at the base, and by the nature of the 

 pollen-masses ; from Encnemis it differs in the form of the 

 flowers, and in their regularity. It may be thus defined.

66. GOVENIA Icujenophora ; pseudobulbo ovato vagina lagena;formi utricu-

 obtuso omnino glabro, sepalis petalisque obtusis. 



For this very distinct and curious species of Govenia I am 

 indebted to John Rogers, Esq. Jun. who imported it from 

 Mexico, and has obligingly furnished me with the following 

 note concerning it. 



*' Root a solitary tuber ; the old not perishing until the 

 new one is nearly full grown, but then dying away com- 

 pletely ; about the size of a duck's egg, forming above- 

 ground, and of a bright green, marked with the scars of 

 three or four sheaths. The innermost sheath which sur- 

 mounts the tuber is entire, and resembles a Florence flask in 

 shape; it is about eight inches high, two to three in diameter 

 at the base, and three-quarters at its throat ; translucent, or 

 semi-transparent, containing about one-third of a pint of 

 water. 



" Leaves two, opposite, lanceolate ovate, eighteen inches 

 long by four to five broad ; articulated with their petioles, 

 just at the top of the pitcher. The petioles are acutely four- 

 angled, sheathing, so that their transverse section is an 

 equilateral rhomboid, with concave sides. The flower-stem 

 rises from the bulb, within the pitcher, and opposite to the 

 midrib of the outer leaf; about three feet high, bearing 

 from forty to fifty flowers, which expand rapidly, and con-
