further, both the varieties of the Indian plant are often found in 
a double or triple form, and are therefore equally entitled to the 
appellation fastuosa. 
What Willdenow says concerning the Datura Metel, after 
having the advantage of the second edition of the Species Plan- 
tarum, and of several accounts by excellent botanists, is liable 
to great objections, so far as relates to the Hummatu. He di- 
stinguishes it as pericarpiis spinosis, foliis cordatis subintegris, 
and adds, calyx non angulatus sed teres: but the figure of the 
Hummatu has not cordate leaves, and the angles on its leaves 
are fully more prominent and sharper than those of the Dutra 
rubra (Herb. Amb. v. 243. t. 87. f. 2.), which Willdenow quotes 
for the D. fastuosa : and further, the calyx of the Hummatu is 
most evidently angular. The description entirely agrees with 
the figure. *'* Folia in oris in cuspides seu angulos sinuata. 
Calyx quinque costis, quz in foliorum (laciniarum) cuspides in- 
currunt, in longitudine striatus." It must be further observed, 
that there is no indication whatever, either in the figure or de- 
scription, of the Hummatu being pubescent ; but I must confess, 
that no great stress can be laid on this point, because on the sub- 
ject of pubescence Rheede is often negligent. The only other 
circumstance, by which Linnzus endeavours to distinguish the 
Datura fastuosa from the Metel, is, that the former has pericarpia 
tuberculata and the latter pericarpia spinosa: but, if the Dutra 
rubra of Rumphius be the D. fastuosa, as Linnzeus admits, its 
pericarpium is fully as much entitled to the appellation spinosum, 
as that of the Dutra alba; and he i is equally silent respecting the 
pubescence of his plant. 
M. Poiret (Enc. Meth. vii. 461, 462. ) gives the synonyma of 
the Egyptian and Indian species at greater length than Willde- 
now, and I have great deference for his opinion and confidence 
in his accuracy; yet I can discover nothing in his account to
