and style are far exserted, the filaments being inserted above 
the base of the corolla, where the tube is contracted, and 
closed internally by a ring of dense villous hairs. The 
berry is red, globose, and shorter than the persistent calyx, 
which increases in size to the length of 5 lines. The seeds 
are numerous, whitish, compressed, subreniform, but were 
not ripe when seen. 
DUNALIA. 
Among the plants sent from Peru by Mathews is one 
marked Lycium obovatum, but it is clearly not the one 
figured under that name in the Flora Peruviana.* In its 
* I have searched in vain for this plant in the herbarium of Ruiz and 
Pavon in the British Museum, nor can I find it elsewhere. In the herba- 
rium of Sir Wm. Hooker there are, however, three plants from central 
America that bear much resemblance to it. It cannot be a true Lycium 
on account of the estivation of its corolla which is valvato-plicative (not 
imbricate) and its lobes are acute with pubescent margins (not rounded and 
smooth) ; it appears to me that with some others I shall point out, these 
will form a distinct group; they possess a habit widely different from 
Lycium, although they are all spiny shrubs, generally with 1 or 2 violet 
or crimson flowers growing out of the fascicles of rather small fleshy leaves 
that cluster upon the spines; the cérolla is usually broader and more 
tubular than in Acnistus or Lycium, with stamens often unequal and in- 
cluded; the calyx has generally acute lobes, and is not pentagonous with 
obtuse lobes as in Acnistus, They offer much resemblance in external 
appearance to the species of Dunalia, above described, but they want the 
intermediate tooth in the corolla and the appendiculate stamens of that 
genus. I propose to call them by the name of Lycioplesium from Lycium, 
and Answoy, approximatus. It may be said that they should, like the 
Lyciobatos of Endlicher, form a distinct section of Lycium, but on account ~ 
of the estivation of the corolla, the generic character, so altered to admit 
of them, would necessarily include Acnistus, Salpichroa, Chenesthes, and 
Tochroma ; genera decidedly inadmissable. The following is therefore 
offered as the generic character. = eegeer
