has a creeping rhizoma, 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. 
AGANISIA. Perianthium patens, equale ; sepalis lateralibus haud basi pro- 
ductis. Labellum liberum, mobile, indivisum, concavum, hypochilio parvo 
concavo, ab epichilio cristá transversá glandulosa diviso. Columna erecta,

ecristata. Rostellum elongatum.  Pollinia 4, collateralia, per paria con-

66. GOVENIA lagenophora ; pseudobulbo ovato vagina lagenzformi utricu-

obtuso omnino glabro, sepalis petalisque obtusis. 
For this very distinct and curious species of Govenia 1 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-
