This superb Himiscus, Professor Boser had long known 
as an inhabitant only of the gardens of cultivators : but 
lately, he says, “ having made an excursion to the Riviere 
noire, and stopped at the house of M. Grnéve, a zealous 
cultivator, with whom I remained some days, occupied ™ 
examining the curious plants in his garden, when my atten- 
tion was struck by the languid appearance of this Hisiscvs, 
which M. Genéve assured me that he had been in the habit 
of seeing in the forests of the Riviére noire, and of trans 
porting to his garden for a period of twenty years ; but 
that he could never cultivate it with success. The nest 
day he conducted me to the mountains, where I found many 
trees of the Hiziscus, of considerable size, and cover 
with flowers : and where I made on the spot my drawing 
and description.’’ Professor Bosrr has distinguished it by 
the name of his intelligent host, to whom we are indebted 
for the discovery of its phace of growth. 
If this shrub be not already in our collections, as I sus- 
pect it is, through the influence of Mr. Trxrair and the 
late Mr. Barcray, cultivators should hasten to procure what 
would prove so great an ornament to the stove. : 
M. Boger refers it to the “ Cremontia’”’ tribe, notwith- 
standing that the corolla is uot “ convoluto-cylindracea, 
where it ranks with H. lilijforus, Boryanus, and fragilis, al! 
natives of the Mauritius as well as of Bourbon.
