seen to distinguish it sufficiently from all of them. As to leaves it most resembles
the Tavoy specimens of P. a-umimla (type) as understood by Mr. Clarke. In the
Kew collection the plant most liko this ia foliage is Henry n. 4153 from Ichang,
C.China, and there noted by Mr. Hemsley as " P . tincioria Noes var., vel species
propria." The Chiueso plant has, however, much broader bracts than ours though it
lias a similai-ly condensed infloroseencc. Sz/poestes salicifoUa 0. Kuutze, represented at
Kew by an authentically named, bat flowerless, scrap, also resembles this somewhat
ill foliage aTid inflorascenco as vrell as iu bracts.

This very distinct plant was on examination considered by one of us to be a new
species of Peristrophe nearly related to P. fera Clarke. Specimens were sent from
Calcutta to England and in compliance with our request Mr. C. B. Clarke, whose
knowledge of the Acanthacece is very great, kindly compared them with the
Peristrophe material preserved in the Herbarium of the Royal Gardens, Kew.
i l r . Clarko finds this plant apparently identical with some oP the examples of his
" P . Jcr^i.'' collected by Hooker and Thomson in Khasia at 2—4,000 feet elev. and
named, in their Uerh. Ind, Or., " P . tinctorvt,'" of which P. fera is perhaps ,only the
wild state. Mr. Clarke deprecates the separation of the present plant as still another
species. With this feeling wc agree; the form is, however, so distinct, both from
what has been described as typical P. fera and from what has been distinguished
as P.. fera VAB.. intermsdia, that it is here accorded the rank of a new variety.

Sir Joseph Hooker, in Flor. Brit. Ind. 1. c., remarks that the long persistent styles
free to the base, serving to attach the fruit to foreign bodies, is unique in this genus,
and that it indicates that the species should form a separate section; he also alludes
to the siuguLirity that though provided with so obvious a means of transport the species
should be so rare in India.
