with the petiole sometimes auricled at the base, uppermost sessile and deeply amplexi- 
caul, Peduncles axillary and subterminal, often forked ; heads 4-4 in. diam.; 
perianth white, 5-cleft. Stamens 8. Styles 2-3, slender, connate below, stigma capi- 
tate.—It is curious that of 60 specimens examined not one bearsripe fruit. Meissner and 
Clarke (mss.) describe it as 3-gonous, but I find both digynous and trigynous flowers. 
Meissner’s var. B. subvillosa is a hirsute leaved state. Hamiltons P. ciliatum is a very 
doubtful plant; according to Don’s description it differs from P. microcephalum only 
inthe decumbent stem. Meissner describes the peduncles as sometimes hispidulovs, 
but I never find them so.

5-fid. Stamens 6-8. Nut trigonous.—I have seen only a few specimens. The habit, 
and naked petioles with minute basal auricles and eciliate bracts distinguish this from 
P. microcephalum. Meissner is in error in citing Wight’s t. 1805 for this; it is 
clearly p. spherocephalum.
