RHODODENDRON THISATJDIENSE. 
A Rhododendron! would be, we doubt not, the involuntary 
exclamation of any one on first seeing this remarkable species, 
far more resembling, in its flowers at least, a Correa or Thi- 
baudia than any of those many varieties of Rhododendron 
known to our gardens or greenhouses. It was exhibited at a 
meeting of the Floral Committee in May of the present year, 
and attracted a good deal of attention from its 44 variety, beauty, 
and remarkable formand a first-class certificate was awarded 
to Mr. Wm. Bull for it. 
A somewhat interesting notice of it appears in the 4 Scottish 
Farmer,’ in which the writer questions, whether 4k it be really a 
new species, but a specimen of the rare Rhododendron Keysii at 
a less advanced stage of flowering than that from which Sir 
Wm. Hooker took the drawing of 11. Heysii figured in the 4 Bo¬ 
tanical Magazine,’ t. 4875 ; at the same time we admit that this 
is not altogether clear, and that Mr. Bull has better grounds 
for holding his specimen to be a distinct species than the 
makers of many species which have never been challenged.” 
The writer then proceeds to notice the peculiarities of each of 
the tw 7 o varieties, and especially remarks on one remarkable 
distinction, viz. that R. Keysii has the trusses of flowers on the 
old wood, while those of R. Thibaudiense are terminal. We 
believe that the opinion of English botanists is in favour of 
their being distinct. 
44 We do not know,” the writer adds, 44 any Rhododendron 
which more directly and, as it were, by its mere outward ap¬ 
pearance, vindicates the title of the genus to be classed 
among the Heaths. It is no uncommon thing to hear non- 
bp tanical horticulturists wonder what Rhododendrons have
