Mr. Thwaites’s Aristolochia. 
Nat. Ord. ARISTOLOCHIACER.—GYNANDRIA H2EXANDRIA. 
Gen. Char. (Vide supra, Tas. 4361.) 
ARIstoLocnia Thwaitesii ; erecta suffructicosa paululum basin versus ramosa, 
ramis velutino-villosis, foliis longe lanceolatis subcoriaceis glabris subtus 
sericeo-villosis, pedunculis subradicalibus, floribus racemosis oppositis peri- 
anthio bis arcte geniculato-flexuoso, limbo oblique truncato obscure 5-lobo 
intus copioso glanduloso-villoso lobis acutiusculis. 
Seeds of this very remarkable Aristolochia were received from 
our valued friend Mr. Thwaites, discovered by him in one of his 
excursions in the interior of Ceylon, and it flowered in the stove 
of the Royal Gardens early in March, 1856. It is the hand- 
somest of all the Hast Indian Aristolochia, and remarkable as 
Well for the peculiar form of the perianth, as for the long narrow 
leaves. The flowers emit a fragrant smell, a good deal resembling 
that of Caladium (or Colocasia) odorum. It appears easy of culti- 
vation and flowered with us in March. 
Descr. From a tuberous caudex, or rhizome, several fleshy 
roofs are emitted, and this caudex bears, above, a cluster of several 
erect, terete, downy stems, about a span high, simple or a little 
branched only at the base, leafy for their whole length. eaves 
alternate, four to five inches long, spathulato-lanceolate, with a 
short sudden acumen, the margins quite entire, the base taper- 
ing into a short, terete petiole ; above glabrous, beneath downy 
or almost velvety. From the base of the stem, or rather from 
the top of the rhizome, the fower-stalks are clustered, erect, 
three inches long, bearing a raceme of fragrant flowers, of which, 
on each raceme, only one opens at a time; opposite each flower 
or bud is a éract. The perianth is very curious in shape, being 
a long ¢wée contracted in the ‘middle, and twice bent like a 
JUNE Ist, 1856.
