Wallich. The leaves are more than a foot long ; the scape 
is terminal upon a large oblong pseudo-bulb, and is termi- 
nated by a sheath formed of numerous imbricated bracts, out 
of which appear eight or nine white flowers, stained with 
yellow near the point of the lip, and having an unpleasant 
smell, very like that of the Barberry blossom. 
152. BATATAS betacea ; foliis ovatis cordatis angulatis et subquinquelobis 
acutis, racemo contracto eomposito, sepalis acuminatis, tubo corolle limbo 
circulari longiore, radice fusiformi sanguineá. 
This is a very handsome twiner, and seems likely to rival 
Ipomea Horsfallie, from which it differs not only in habit, 
but in the colour of the flowers, which are a very delicate 
pale violet, with a much deeper purple eye. A drawing of 
it was sent me in March last by the Rev. J. B. Reade of 
Clapham, with a letter informing me that it had flowered 
with his friend Mr. Waterhouse of Halifax, who “ states that 
the root is a tuberous one, and came accidentally among 
some Orchidacedus plants from Demerara, and possesses the 
peculiarity of being exactly similar to Beet Root, with the 
same purplish red colour." Lately 1 again received a notice 
of it, with a figure, and the following additional particulars, 
from Mr. William May, Nurseryman, Ripon, who has it 
for sale. 
“ The Gardener to Mr. Waterhouse says that it is a most 
profuse bloomer, and prefers the cool part of the plant stove ; 
he states that he tried two plants of it, the one at the cool 
end near the door and farthest from the fire, and the other 
at the warmest end nearer the fire; in the former of which 
he finds it succeed much better and bloom much more freely 
than at the end nearest the fire. From this circumstance he 
thinks it will be a greenhouse and not a stove plant. Since 
it has been in my possession I have had it in various tempe- 
ratures, and find it prefer the greenhouse, where it has plenty 
of air; but having had it only two months during summer, 
I am not authorized in saying it is decidedly a greenhouse 
plant." 
153. ODONTOGLOSSUM Clowesii ; pseudobulbis ovalibus diphyllis, foliis 
ensiformibus angustis erectis scapo longioribus, racemo paucifloro corymboso,
