Division I. 



CURVE'MBRI^ (from curvus, curved, and embryo, (f. 21. 

 b.e.f.). Radicle curved back upon the edge of the cotyledons. 



Suborder I.

 to the disposition of the petals resembling that of a butterfly

 Curvembryse, Bronn. dis. p. 131. Cyteophytum, Neck. elem. 3. 

 p. 1. Leguminosac, Batsch. tabl. afF. 95. 



Embryo with the radicle curved back upon the edge of the 

 cotyledons, lying above the commissure formed by the lobes (f. 

 21. b. e. f.). Sepals usually imbricate in aestivation, rarely some- 

 what valvate. Petals disposed into a papilionaceous corolla or 

 a pea flower (f. 24. b. f. 25. b., &c.), therefore always irregular. 

 Stamens inserted in the bottom of the calyx (f. 22. e.), or pcri- 

 gynous. Plants with simple, trifoliate or simply pinnate leaves. 



1. Phylloloba; (from r/ivXXoj', phyllon, a leaf, and \oftog, 

 lobos, a lobe ; in reference to the lobes of embryo or cotyledons 

 being foliaceous). D. C. Coli/l<donsthin,foliaceous(f.2l.a.f.). 



Tribe I.

 characters). Spreng. anl. 2. p. 741. Bronn. diss. p. 131. 

 D. C. legum. mem. V. prod. 2. p. 94. 



Corolla papilionaceous (f. 22. c. f. 24. b.). Stamens free (f. 23. f. 

 f. 24. c.). Legume continuous (f. 22. d.), never articulated. 

 Cotyledons flat, leafy (f. 21. a. 6.). This is a very natural tribe, 

 known by its papilionaceous flowers, free stamens, and unarticu- 

 lated pods. 



I. MYROSPE'RMUM (from pvpov, myron, myrrh, and 

 (Ttreppa, sperma, a seed ; the seeds and cells yield a balsam that 

 has a strong smell). Jacq. amer. (1736)p. 120. Lam. ill. 341.

LIN. SYST. Decdndria, Monogynia. Calyx campanulate, 5- 

 toothed. Petals 5, the upper one larger than the rest. Stamens 

 10, free. Ovary stipitate, oblong, membranous, 2-C-ovnlate, 

 bearing a lateral, ascending, filiform style towards the apex. 

 Legume with a naked stipe at the base, but amply winged at the 

 apex, samaroid, indeliiscent, 1-celled, 1-2-seeded, bearing the 

 style laterally towards the apex. Seed enwrapped in balsamic 

 resin. Radicle incurved in the first section, in the rest unknown. 

 Cotyledons thick and flat. American trees, with abruptly-pin- 

 nate leaves, and with the leaflets usually fidl of pellucid dots, 

 the glands or dots are oblong-linear, as in Samydete. The ter- 

 minal leaflet usually -solitary. Perhaps a proper tribe.

1 M. FRUTE'SCENS (Jacq. amer. 120. t. 174. f. 34.) leaves 

 membranous, deciduous ; legume with a reticulately-veined wing ; 

 style permanent. Jj . S. Native of South America, in bushy 

 places at Carthagena and St. Martha, on the declivities of 

 mountains in Caraccas, as well as on the banks of the Rio Gua- 

 rico. H. B. et Kunth, nov. gen. amer. t. 570. and 571. Leaflets 

 7-8 pairs, alternate, somewhat crenulated, oval, emarginate, 

 marked with pellucid lines. Legume nearly 2 inches long, with 

 the stipe inclosed in the calyx. According to Jacquin this is 

 an inelegant shrub. Leaves alternate, pinnate, deciduous, with 

 commonly 3 pairs of leaflets and an odd one, which nre quite 

 entire and smooth. Flowers of a whitish rose-colour, disposed 

 in terminal, simple, or bifid racemes. The seeds and the cell 

 of the legume yield a balsam that has a strong unpleasant smell. 



Shrubby Balsam-seed. Shrub 10 feet.

 xylon, wood ; the wood is resinous and sweet-scented). Mutis, 

 Lin. fil. et Kunth. Stamens deciduous. 



2 M. FUBE'SCENS (D. C. prod. 2. p. 95.) branches and pe- 

 tioles hairy ; leaflets ovate-lanceolate or oblong, rather membra- 

 nous, smooth above and pubescent beneath, rather acumin- 

 ated, emarginate. J? . S. Native of South America, near Car- 

 thagena and Popayan. Myroxylon pubescens, H. B. et Kunth, 

 nov. gen. amer. 6. p. 374. M. peruiferum, Lamb. ill. cinch. 92. 

 t. 1. Leaves rather membranous, marked with line-like dots. 

 An elegant tree, with white flowers disposed in terminal racemes. 

 The bark is filled with white resin, which, according as it abounds 

 more or less, changes the colour to citron-yellow, red, or dark 

 chesnut ; the smell and taste are grateful, balsamic, and aromatic, 

 resembling those of Red Peruvian Balsam, and sold in druggists' 

 shops under the name of white balsam. The legume contains 1
