clustered flower-spikes, and in floral details. From each other they 
differ in the following particulars : 
Petiolar glands prominent ; midrib channelled 
above ; flower-spikes slender, equalinlength S. pleiostachys. 
Petiolar glands obscure or absent ; midrib not 
channelled above ; flower-spikes stouter, un- 
equal in length Wee ie iui .. S. anadenum. 
The latter is one of the few species showing well-developed 
bracteoles subtending both male and female flowers.

Beautiful flowering specimens and samples of the bark of this 
plant were collected in the forests of the eastern provinces of 
Bolivia by Mr. Cecil Gosling, who has recently been on a journey 
in this region under the auspices of H.M. Government. e 
states that a decoction from the bark is there used as a substitute 
or quinine, and that this has the local reputation of being

morada ” ; a note on the alkaloid which has been separated from 
the bark was published in the Pharmaceutical Journal for

_ Chrysoxylon__febrifugum (Pogonopus febrifugus, Benth.) was 
described by Weddell in oe (Hist, Es Senge 100 hea a 
specimen collected by him in the province of Cordillera, Bolivia. 
his specimen consists of leaves and an infructescence only, and no 
flowers ; the leaves are very shortly petiolate and quite densely 
tomentose on the lower surface, whilst the infructescence is glabrate. 
In 1854, however, 
already been used 
description, and a fi 
tomentose. On account of these slight differences, therefore, we 
are rather doubtful whether Weddell was correct in considering 
these two specimens to represent the same species ; but, on the 
other hand, y have made observations in the field which — 
induced him to adopt this view.
