VOYAGE TO SANTAREM 67 
tipped with a kidney-shaped knob (the real fruit), 
is a picturesque object, notwithstanding its humble 
size. With the Caju grew the Caimbe [Curatella 
americana, L.), a small tree not unlike a stunted 
oak in habit and in the sinuated leaves, which are, 
however, so rough that they are used in lieu of 
sandpaper by the carpenters of Santarem. It is 
one of the very few trees of the hot plains that 
have deeply-furrowed bark, which accounts for the 
name Alcornoque (Cork tree) I afterwards heard 
given to it on the llanos of the Orinoco, where also 
it is a common tree. But the finest of these trees 
was the Suca-uba [Plumiera phagedenica, Mart.), an 
Apocyneous tree which grows to about the size of 
the common holly, and has long coriaceous leaves 
of the richest green, with terminal clusters of white 
flowers the size of primroses, but very fugacious, 
followed by curious spindle-shaped twin pods full of 
winged seeds. The milky juice of the Suca-iiba 
has great repute as an anthelmintic. Another tree 
of similar growth, but of the family of Rubiads 
(Tocoyena puberula), had wider rugose leaves, and 
ochre -yellow flowers with a tube 4 inches long. 
A Murixi [Byrsonima P'dppigiana, A. Juss.), with 
numerous racemes of pretty yellow flowers, and 
another [Byrsonima coccolobcefolia, H. B. K.) with 
similar racemes of pink flowers, and leaves like 
those of the Cajii, were both very ornarnental. 
With these grew here and there Hylopia grandi- 
flora, St. HiL, an Anonaceous tree, notable (like 
many others of the order) for its pyramidal mode of 
growth, for its two- ranked, rigid, lance -shaped 
leaves, and especially for the thick leathery petals 
(six, in two rows), being of a fine rose colour within,
