 scien. Aug. 1827. p. 285.) trunk arboreous, coated, with ver- 

 tical, somewhat diaphanous lamina ; flowers racemosely-panni- 

 cled, decandrous. Tj . G. Native of Africa, at the White River.

Paper-bearing Amyris. Tree. 



Cult. The species of Amyris grow freely in a mixture of 

 loam and peat, and cuttings root freely in sand, under a hand- 

 glass, those of the stove species in heat. 



II. PACHY'LOBUS (from Tra X ve, pac/iys, thick, and Xo/3oe, 

 lobos, a lobe ; the lobes of the cotyledons are thick). 



LIN. SYST. unknown. Fruit oval, black, superior, about the 

 size of a hen's egg, 1 -celled, containing a large embryo, having 

 2 3-parted cotyledons, the lobes large, thick, angular, and 

 twisted. A large tree with impari-pinnate, smooth leaves, with 

 the leaflets nearly opposite, ovate, acuminated, entire, the young 

 branches rather tomentose. 



1 P. EDuYis. Ij . S. Native of the island of St. Thomas, 

 in the Gulf of Guinea, where the fruit is much esteemed by the 

 inhabitants, and sold in great quantities in the market of St. 

 Ann de Chaves, under the name of Safu : in taste it is bitter 

 and astringent. It is usually roasted. There is another species, 

 which goes under the name of Pasco, which appears only to 

 differ in having hairy leaves, and in the shape of the fruit. The 

 whole description of this tree is given from memory, as we have 

 had no specimen to examine. 



Edible Safu. Fl. Nov. Tree 40 feet. 



Cult. For culture and propagation see stove species of 

 Amyris.

Flowers hermaphrodite, rarely unisexual. Calyx 5-parted, 

 regular, permanent, either imbricate or valvular in activation. 

 Petals 5 (f. 20. b.), inserted in the calyx, imbricate, rarely val- 

 vate in aestivation. Stamens twice the number of the petals 

 (f. 20. c.), hypogynous, those opposite the petals shorter than the 

 others, usually monadelphous at the base (f. 20. d.). Ovary 

 solitary or simple, or several together, each with a separate style, 

 with an usually dilated stigma. Ovula 2, collateral, ascending. 

 Capsules usually several, rarely single (f. 20. k.~), dehiscent, 

 splitting lengthwise internally. Seeds erect, in pairs, or solitary, 

 with or without albumen, but usually furnished with aril. Radicle 

 superior at the extremity most remote from the hilum. Cotyledons 

 thick in the species without albumen, and leafy in those with al-

bumen. Trees or shrubs, with compound, dotted, alternate, ex- 

 stipulate leaves, and terminal racemes or panicles of bracteate 

 flowers. Connarus can only be distinguished from Legumindsce by 

 the relation the parts of the embryo have to the umbilicus of the 

 seed (R. Brown, congo. 432.) that is to say by the radicle being 

 at the extremity most remote from the hilum. The want of 

 stipulas is, however, usually sufficient to distinguish them. It 

 differs from Terebinthacece in the want of resinous juice. 



Synopsis of the Genera. 



1 CONNA'RUS. Calyx 5-parted. Petals imbricate in aesti- 

 vation. Stamens somewhat monadelphous at the base. Carpels 

 5, each bearing a style, biovulate, some of them are usually 

 abortive. Capsules sessile, 2-valved, 1-seeded; seeds exalbu- 

 minous. Leaves trifoliate or impari-pinnate. 



2 OMPHALOBIUM. Calyx 5-parted. Petals 5 (f. 20. b.), im- 

 bricate in aestivation. Stamens monadelphous (f. 20. rf.), or 

 somewhat polyadelphous at the base. Carpels 5, each bearing a 

 style. Capsules 1-5, legume-formed (f. 20. k.), 2-valved, dehis- 

 cent. Seeds twin or solitary, exalbuminous. Leaves trifoliate 

 or impari-pinnate.

 tals 5, covered with glandular hairs. Stamens 5. Glands 10, 

 twin, between the stamens. Carpels 5, joined at the base, 1- 

 seeded. Seeds exalbuminous. Leaves pinnate.
