Sikhim (Hooker fil. et Thomson! in Herb. Mus. Brit.), 4000—6000 
feet above the sea. 
'This plant was distributed by Drs. Hooker and Thomson under 
Hedera subcordata, Wall, but it is not identical with the species 
described by Don under that name from Wallich's authentic specimen. 
The panicles are 13 foot long, and at the base (as are the young leaf- 
branches) furnished with persistent scales (perulze). 
2. P. subcordatum, Seem. mss. in Herb. Mus. Brit. ; glabrum, foliis 
pinnatim 5-foliolatis, foliolis longiuscule (1-14 poll. long.) petiolulatis 
ovato-oblongis acuminatis, basi rotundatis vel subcordatis, serratis, ser- 
raturis obtusiusculis, floribus distincte racemosis, pedunculis pedicel- 
lisque glabris, ealyculo integro.—Hedera subcordata, Wall. Cat. n.

4917, in Herb. Soc. Linn. Lond.); Khasia Hills (Hooker fil. et 
Thomson !). 
Blade of leaflets from 4—53 inches long, 3-4 inches broad. 
Both this and the preceding species differ in their truly racemose 
flowers from the other species of Pentapanax, but they agree so well 
in every other respect, that I cannot separate them generically. 
. P. umbellatum, Seem. mss. in Herb. Mus. Brit., foliis pinnatim 
5-foliolatis, foliolis petiolulatis ovatis acuminatis, basi obtusis, serratis 
coriaceis, floribus umbellatis, umbellis compositis, pedunculis pe icel- 
lisque hirtellis, calyculo subintegro (v. s. sp.).—Khasia (Hook. fil. et 
Thomson ?).
