t. 5021), ab utraque caulibus foliisque sanguineo-velutinis et floribus 
miniatis differt; ab illa stipulis linearibus elongatis acuminatissimis et 
pedunculis multifloris petiolos excedentibus recedit. 
Frerba subcarnosa, ramosa, erecta, 0°5-1:0 m. alta, pilis leprosis sanguineis 
patentibus mollibus paucis albis intermixtis vestita, ramis teretibus 
articulatis. olia longe petiolata, oblique cordata, absque petiolo usque 
ad 25 em. longa, plus minusve lobulata, simul denticulata, longe acuminata, 
lobis basilaribus rotundatis, subtus sanguinea, supra praeter venas 
sanguineas viridia cum zona pallidiore; petioli teretes, usque ad 15-18 
em. longi; stipulae lineares, acutissimae, circiter 3 cm. longae. Cymae 
axillares, solitariae, 8-10-florae, pendulae, foliis breviores, bracteis parvis 
inconspicuis. Flores hirsuti, unisexuales, monoici, miniati, 3°5-4°5 cm.

This and the two species with which it is compared in 
the above description are very closely allied in structure. 
Indeed B. Bowringiana and B. laciniata have been treated 
as varieties of one species by De Candolle and others; but 
the plants cultivated and figured in this Magazine under 
these names are quite distinct. The cultivated B. cathayana 
is exactly the same as dried specimens in the Kew Herbarium, 
bearing the numbers 9198 and 13516, collected by Dr. A. 
Henry near Mengtze, Yunnan, at an elevation of 5,000 ft. 
Drsoriprion.—Herb, 2-3 ft. high, with fleshy stems and 
leaves, clothed with long, crimson, soft, scurfy hairs, 
interspersed on the branches with a few white ones.
