Amongst Indian brambles this plant most resembles R. eUipticuB Smith; but
i t may at once be distinguished by the colour and texture of its foliage, the abruptly
acuminate leaflets, and the very different inflorescence. The drawing was made
from a specimen collected in the Bâmsu Valley in Tehri-Garhwal, where I have never
observed the fruit becomiog succulent, the carpels always remaining dry like acheues,
and the styles persistent.

KACOIN HILLS: Chcsyan, 3700 f t . ; Pottinger!
T h i s species has been made the type of a new genus of SazifriKjaceae, in the
t r i b e Escallonieae near Itea, which it resembles in having a similarly partible style with
a similarly half-superior ovary. It differs markedly, however, from Itea in having 3
carpels in place of 2 and in the capsule when deliiscing leaving the three filiform
placentas persistent. The leaves too, which are like those of a Cinnamon, or of a
Melastomaceous plant, give the plant a facies of its own.
Unfortunately the only specimen brought by Capt. Pottinger has been collected just
as the plant was passing out of flower; the petals and anthers have ail dropped and
though the scars left show that there are 5 petals it is at present impossible to say
whether they are imbricate or valvate.

This line species, though provided with 2 lateral wings of the nature of the
wings present in the fruits of species of Torminalia § Pentaptera is really, as Mr. Clarke
has pointed out, more nearly allied to § Catappa than to the Pentapteras. As no flguro
of the species has ever been published the present opportunity is taken to reproduce
tho unedited drawing of the plant loft by Dr. Roxburgh in the Calcutta Herbarium
Collection.
