work by Mr. Lynch. Specimens from both Mr. Bent and 
Mrs. Lort Phillips are growing most luxuriantly at Kew, 
and have attained much longer stems than the native ones, 
or than that figured in the plate. The joints root freely 
at the articulations, and often at the tips also. As to the 
genus of this plant, that depends on the value attached to 
Kleinia, Linn., as distinct from Senecio. Of absolute dis- 
tinction between these there is none, but Kleinia forms a 
fairly circumscribed group, distinguished by a succulent 
habit, cylindric, ecalyculate involucre, long, narrow, uni- 
seriate bracts, and homogamous discoid flowers, the outer 
of which have small conical appendices to the style-arms. 
For horticultural usage the name is very convenient. 
Notonia, DC., is absolutely identical with Aleina. 
Descr.—A decumbent, almost leafless, fleshy perennial. 
Stem consisting of a few superposed curved or crooked, 
fleshy, cylindric joints, the upper of which is laterally arti- 
culate with that below it by a very narrow area below the 
point; joints four to fifteen inches long, by one half to 
three-quarters of an inch in diameter, sparsely spinulose, 
incurved or inflexed, dull green, striated, base rounded, tip 
narrowed, obtuse. Leaves produced only at the growing 
tips of the young joints, about a quarter of an inch long, 
filiform, terete, fleshy, transformed into shining recurved 
spinules, with a swollen base as the joint develops. Peduncles 
one or two, terminal, erect, deflexed, or horizontal, three 
or more inches long, furnished with a few small, narrow 
bracts. Involuere about an inch long, by half an inch in 
diameter, cylindric, naked at the base; bracts narrowly 
linear, acute, shorter than the flowers, striate. Flowers 
forming a depressed head, much broader than the in- 
volucre, about an inch and a half in diameter, of a bright 
vermilion colour mixed with orange-yellow.—J. D. H.
