A native of Cape Colony, gathered by Mr. Cooper. 
Leaves twenty to thirty in a dense sessile rosette three inches 
broad, an inch and a half high, oblong-lanceolate, narrowed 
a little between the middle and the base, narrowed gi'adually 
upwards into a long pellucid awn. a quarter of an inch thick in 
the middle, the upper third marked on both sides with limpid 
lines, the edge and awn ciliated with minute hmpid setae, colour 
pale green without spots, the face slightly convex, the back 
broadly rounded. Inner leaves erect, outer patent. Peduncle 
nearly a foot long, exclusive of the raceme. Flowers twelve to 
twenty, the upper sub sessile, the lower shortly pedicellate. 
Bracts lanceolate, three to four lines long. Perianth seven to 
eight lines long, white striped with gi'een ; the distinctly bilabiate 
limb haK as long as the tube. 
Closely alhed to H. inUfera (Tab. 234), but the leaves are 
different in size and shape, and not ciliated on the keel, and the 
peduncle is much taller.

I have before alluded to the pro2Der treatment of the Hatvorthia 
section of the genus Aloe during the progress of this work, and I 
have nothing to add to the obseiwations I have offered. If the 
present species receives the treatment I have referred to, it will 
thrive well and develope its delicate foliage, which constitutes the 
beautv of the plant. It was sent to me from South Africa by 
Mr. Thos. Cooper.— TT". JV. S.
