The Kew Herbarium contains a specimen collected twenty 
years ago, at Loanda, by Dr. Welwitsch, who appears to have 
been disposed to constitute it a new genus, but subsequently 
referred it to Huernia. He notes that in habit it is “late 
ceespitosa.” 
The Royal Gardens, Kew, is also the fortunate possessor of 
specimens, both living and in spirit, as well as of drawings 
and analyses from His Excellency Sir Henry Barkly, Dr. Shaw, 
and Mrs. Barber of a second species, from Little Namaqualand. 
It is closely allied to D. elegans, the flowers being extremely 
similar, but the branches appear to have more numerous 
angles, and the two lateral setz of the spines are more slender, 
and detlexed instead of erect. I am indebted to Professor 
Thiselton Dyer for the accompanying revised description of _ 
the genus and of this species. 
Duscr. Stems succulent, leafless, caspitose, four to six 
inches high, strongly angled, the angles furnished with 
patent spinous processes, each bearing two lateral erect barb- 
like set. Flowers produced according to Decaisne from the 
axils of the branchlets, but apparently also from the branches 
themselves between the spinous angles. Flowers sub-erect (the 
pendent habit given in the plate is due to the plant having 
been grafted) ; pedicels one-third of an inch, accompanied by 
one or two membranous acute bracteoles. Calya 5-lobed, lobes 
one third to half an inch long, linear-deltoid, acuminate 
with a small linear herbaceous appendage arising between 
each pair of lobes on the inner side. Corolla narrowly cam- 
panulate, 5-lobed, tube externally marked with brownish- 
purple streaks and spots on a lurid yellow ground, internally 
furnished with numerous ‘papilla-like deflexed processes and 
hairs ; lobes deltoid, acute, slightly revolute. Staminal-crown 
5-fid ; segments connate at the base, oblong, white, deeply 
bifid, each tapering into two filiform capitate dark violet 
processes, becoming ultimately flaccid and entangled. Aathers 
broadly ovate, obtuse, with a dorsal incumbent ligulate 
appendage ;_ pollen-masses horizontal, compressed, obovato- 
ensiform with a short funiculus furnished with a linear 
membranous appendage at the base, where it is attached to 
the stigmatic gland. Stigma disk-like.
