tlie one sentr The species differs in Uttle from Bifrenaria, and is probably allied to B. inodora. The flowers 
when expanded are about three inches in diameter. The sepals are convex, those at the side being only slightly extended 
into a chin. The petals have a similar form, are rather inclined to turn back at the edges, and converge over the 
column, which is quite smooth, except just at the base in front. They are a dull nankeen colour with broken brown bars» 
The lip is much paler, with broken rose-coloured streaks, rounded at the point and turned inwards at the base, so as to 
resemble a slipper* When flattened out it has a slightly repand rhomboidal outline ; on its upper side it is hairy, and 
bears in the centre a conspicuous 3-toothed fleshy appendage. The pollen masses are in two pairs, each placed upon a 
short strap, which connects it with a very narrow crescent-shaped gland. It is no doubt the form of this gland which 
has led to the opinion, that the plant is a Scuticaria, the two straps, which shrink up after a few days, having been 
overlooked. 
333. Berberis tripoliata. HaHweg, A beautiful half-hardy evergreen shrub, with variegated 
glaucous spiny leaves, Tlowers smaU^ pure yellow. Native 
of Mexico. (Eig. 168.) 
The charming foliage of this shrub renders it one of the most valuable 
of the species of this interesting genus, even although it requires some 
shelter in our severer winters. To the following account, in the Botanical 
Register, we find nothing to add : 
** This very rare and beautiful species 
was found in Mexico by Mr. Hartweg, 
near the Hacienda del Espiritu Santo, on 
the road from Zacatecas to San Luis de 
Potosi, an immense plrun, occupied chiefly 
by OpuntiaSj stunted plants of Prosopis 
and Yuccas.

tracts of country ; the people called it 
Acrito, and the fruit was much eaten by 
children. Mr. Hartweg did not see it in 
flower. Its sessile, ternate, holly-like
