This is the only Himalayan Jacob's Ladder. It 
was issued by Wallich, and has been dealt with by 
Mr. Bentham, in De Candolle's Prodromus, and by 
Sir J. D. Hooker, in Flora Indica, as P. coeruleum, 
pure and simple, but it is certainly so far different 
from the common European type as to deserve a 
distinctive name for horticultural purposes.

toit now by receiving specimens sent 
for a name from Messrs. Paul & Son, of Cheshunt, 
who obtained it from Colonel Walker. It has larger 
flowers than the European type. In the living speci- 
mens now laid before me the expanded corolla 
measures 14 inch in diameter, the round lilac-blue 
segments being 4 inch broad. The panicle-axis and 
he mature calyx is 4 inch 
long. In leaf, inflorescence, and structure it does 
not differ materially from the European type. The 
seeds ar flatter and more acutely angled. Our 
specimens in the herbarium are from Lahul, Kashmir, 
and Kumaon, where it ascends the mountains to 
12,000 feet. Mr. Dewar tells me that it is sometimes 
called grandiflorum in gardens, but it is quite dif- 
from P. X orm Benth., which is a

NATAL TO THE TRANSVAAL. 
(Concluded from р. 610.) 
— We reached the Warm Baths, 
3400 feet, a natural hot mineral spring, which 
bubbles out of granite rocks tilted up on edge, at a 
temperature of about 140?. One bright summer 
morning before sunrise = had a long bath in th 
water; it is an enervating but new and delicious 
feeling. The besser close to the spring is 
nothing very remarkable, consisting of a large tree 
of Syzygium cordatum, and a few plants of Ficus, 
Aloe, and Asparagus. A few Natal plants grow
