spiny habit it greatly resembles a Lycium or Grabowskya, 
but, on examining the flowers I, found it to possess all the 
essential characters of Dunalia. The genus Dunalia, founded

inclusa. Semina numerosa, parva, compressa, reniformia, albuminosa ; 
embryo cylindricus, annularis. 
Frutices Americe meridionalis glabri vel fomentosi spinosi ; folia crassius- 
cula, oblonga, in petiolum basi angustata, in spinis junioribus subfasciculata ; 
flores pedunculati (1-2) in quoque axilla ; corolle violacee vel rubescentes ; 
bacce rubre vel aurantiace.

glaberrimum ; ramis patentibus, aculeis rigidis, junioribus fasciculato- 
foliosis, adultis nudis ; foliis obovatis, obtusis, crassiusculis, basi in 
petiolum decurrentibus ; pedunculis solitariis, extra-axillaribus, 1-floris,

A shrub 12 feet high, very smooth, leaves including the petiole 14 inch, 
7 lines broad; peduncles 7 lines long; calyx urceolately tubular, 2 lines 
long, with 5 short obtuse lobes, having a small mucro at the apex; 
corolla tubular, purplish violet, 9 lines long, lobes of border short, 
3-angular, erect, with floccose margins; filaments glabrous, arising above 
the base of the tube where it is pubescent ; anthers included within the 
mouth; the style is exserted; the berry is globose, orange coloured. 
2. Lycioplesium nitidum, (n. sp.) :—fruticosum, spinosum ; foliis alternis, 
ovato-oblongis, glaberrimis, crassiusculis, supra lucidis, subtus pallide 
glaucis, rarius in venis tomentosis, margine revolutis, apice obtusis et 
minute retusis, basi cuneatis, in petiolum brevem attenuatis ; floribus 
binis, pedunculis apice incrassatis, corolla rubro-violacea, staminibus 
exsertis. Columbia, Pulzhum, in valleculis latere occidentali. (Jameson) 
v. s. in Herb. Hooker). 
The young shoots (about $ inch long) from which the leaves and 
flowers spring, finally become converted into spines ; the peduncle is 7 lines 
jong, and thickened at its apex; the calyx is campanular, 2 lines long, 
about the same breadth, and has 5 short rounded teeth with a small mu- 
cronate acumen; the corolla is smooth, tubular, 10 lines long, with 5 
small erect lobes with a mucronulate apex and floccose margins ; the an- 
thers are oblong, 2-lobed, cordate at base, yellowish green, affixed at 
base, the filaments being inserted above the base of the tube of the 
corolla, where it is densely pubescent.

ferrugineo-tomentosis ; foliis glaberrimis, crassiusculis, ovalibus, utrin- 
que rotundatis, margine revolutis, supra lucidis, subtus pallidioribus, 
breviter petiolatis ; floribus solitariis, extra-axillaribus ; corolla glabra,
