84 BOTANY OF THE VOYAGE OF H.M.S. HERALD. 
This species is closely allied to P. marginata, St. Hil., from which it differs in the leaves not being 
tomentose on the under side, the petals becomiug glabrous towards the point, and the leaves being 
iirticulated. The tree is about 40 feet high, the leaves are 5 to 7 inches long and from 2i to 3 inches 
broad. The flowers are 3 inches long, and white inside.

irrcgulariter 3-5-fido extus glabro intus tomentoso, petalis (roseis) obovato-oblongis obtusis extus 
sericeo-tomentosis intus plus minus pubcrulis, tubo stamineo exteriore sericeo-tomentoso apice 
dcntato, interiore glabrato apicc soluto in filamentis 5 divaricatis (ut in Eriodendro), stylo glabro. 
T? . Volcano of Chiriqui, Veraguas. 
A beautiful tree, about 30 feet high, with large rose-colourod flowers. The leaflets are uiiknown ; the 
petals are from 3 to 3^ inches long, and i of an inch broad. The stamens are divided at the apex in five 
long filaments, nearly 1^ inch long, distinguishing this species from others hitherto described, and 
bringing it close to Eriodendron, to which genus it would belong, save for the three bracts at the base of 
the calyx and the double tube of the stamens.

Common in most of the forests. 
The wood of this tree, being soft and light like cork, is used for stopping bottles ; the never-sinking 
rafts which, at the discovery of South America, caused such surprise, were then constructed of it, and are 
so still, and have given rise to the popular name Balsa (raft). The prevalence of this plant along the 
coasts of South America and the "W^est Indies has hitherto, it seems, not been sufficiently appreciated by 
historians, but the nature of such a tree might indeed accoimt for much intercourse among the aboriginal 
races, and many an early migration which, under other circumatances, may almost appear inexplicable. The 
silky hair of the capsule of this plant, as well as that of other StercuUacece, is employed for stuffing pUlows 
and cushions.
