342 NATURAL HISTORY OF PLANTS. 
embryo surrounded by a fleshy albumen. These are trees of tropical 
America; four or five species of them are known.’ The leaves are 
alternate, simple, entire, accompanied by two lateral stipules ; the 
flowers are disposed in spikes or racemes at the summits of the 
branches, and the axils of the leaves. 
Amphirrox (figs. 356, 357) only differs from Paypayrola by its 
stamens, the filaments of which are free, and the anthers sur- 
mounted by a pointed prolongation of the connective. Lsodendrion, 
consisting of shrubs from the Sandwich Isles, have the free stamens 
of Amphirroæ, and the non-apiculate anthers of Paypayrola. The 
stigmatiferous summit of their style projects on one side, instead of 
being terminal; the placentas support two or four ovules each, and 
there is no deduplication of the pericarp at maturity. 
Rinorea (figs. 358-362) may be considered as the type of a distinct 
subseries, because the regular or slightly irregular corolla is formed 
: inorea physiphora.

of petals quite distinct to the base, and not adhering to each other 
at this point. The stamens are free, or the filaments united for a 
variable distance ; their back is sometimes bare, sometimes appendi- 
culate ; and the connective is prolonged above the anthers in a plate 
of variable form. On each of the three parietal placentas one or 
several ovules are inserted ; the fruit is a three-valved capsule, with 
seeds smooth, or furnished with a cottony down. 
In a Rinorea of Ceylon, distinguished as a genus under the name 
of Scyphellandra, the very small flower has a sort of disk, represented 
by five scales, each corresponding to the back of an anther.
