HYPERICUM UNDULATUM. 45 
No. 9, O: Pahudiana, contained more chincho-tannic acid than even 
the last.. "The precipitate of alkaloid was minute, and much implicated 
with astringent colouring-matter. Ether dissolved a small portion, in 
which, on evaporation, crystals could be perceived. This bark, in the 
state in which sent, has scarcely any bitter taste; and would be worth- 
less in commerce. -L cannot say what the mature bark might be. after 
some years’ growth, but doubt whether it can ever repay the expense 
of cultivation, - I may remark that this bark a good deal resembles 
that of C. purpurea in its external appearance ; and also that the bark 
of C. micrantha now sent. has much. the same character as that 
which. characterizes the bark of the same Chinchona:as grown in South 
America. 
I find similar characteristic colouring in the leaves of the three spe- 
cies sent, C. officinalis, micrantha, and succirubra. The same also 
seems (a little altered) to. pervade the specimen of wood, marking a 
difference from the heartwood of C. succirubra of many years’ growth 
which I have before examined. | 
HYPERICUM UNDULATUM, Schousb., A RECENT ADDI- 
TION TO THE BRITISH FLORA. 
By T. R: ARCHER Brices, Esq. 
A short time ago I sent specimens of an Hypericum, collected in the 
neighbourhood. of Plymouth, to Mr. J. G. Baker, and. have. been in- 
formed by him that the plant is entirely new to our flora. He- has 
drawn up a description of it, which he has kindly given me permission 
to use. 2

with four slightly-winged angles. Leaves oblong or obovate-amplexi- 
caul, thickly studded with pellucid dots and with a network of pellucid 
veins... Panicle loosely corymbose, the long. lateral branches with often 
only two or three flowers. Sepals always erect, lanceolate, acute or 
bluntish, with pellucid veins and dots, sometimes, but not always, with 
black dots on the back and along the edges. Petals elliptical or ob-
