Smooth Trigonia. Shrub cl. 



Cult. These shrubs are hardly worth cultivating, except in 

 general collections. They will thrive well in a mixture of loam 

 and peat, and ripened cuttings will strike root in sand under a 

 hand-glass, in heat.

 Count de La Cepede, professor of zoology in the museum of natural 

 history at Paris). H. B. et Kunth, nov. gen. amer. 5. p. 142. 

 t. 444. D. C. prod. 1. p. 571. Triceraja, Willd. in Rcem. et 

 Schult, syst. 4. p. 803. 



LIN. SYST. Pentandria, Monogynia. Calyx 5-parted, un- 

 equal. Petals 5, with very short claws. Stamens 5, with un- 



connected filaments ; anthers 2-celled, bursting lengthwise. 

 Ovary 3-celled, each cell containing 8-ovulae. Style 3-furrowed, 

 and at length dividing into 3 parts. Berry 6-9-seeded, 3- 

 pointed from the permanent styles A tree with serrulated leaves 

 and terminal panicles of white, sweet-scented flowers. It is 

 nearly allied to Trigonia. 



1 L. INSI'GNIS (H. B. et Kunth, 1. c.). T? . S. Native of 

 Mexico near Xalapa. Triceraja tinifolia, Willd. 1. c. Triceras 

 Xalapensis, Spreng. 



Shemy Lacepedea. Tree 20 feet. 



Cult. This fine tree will probably thrive well in a mixture 

 of loam, sand, and peat, and ripened cuttings will root in sand 

 under a hand-glass, in a moist heat. 



ORDER XLIV. ERYTHROXY'LE^E. H. B. et Kunth, 

 nov. gen. amer. 5. p. 175. 



Sepals 5 (f. 106.), permanent, concrete at the base. Petal 5, 

 hypogynous, broadest at the base, furnished each with a scale 

 on the inside, with the margins incumbent before expansion. 

 Stamens 10 (f. 106. c.), filaments concrete into an urceolus at 

 the base (f. 106. c.). Anthers versatile, erect, 2-celled, 

 bursting lengthwise at the sides. Ovary 1-celled, con- 

 taining a solitary, pendulous ovula, or 3-celled, the lateral cells 

 empty. Styles 3, (f. 106. d.), distinct, crowned each by a capi- 

 tate stigma (f. 106. d.} or connected almost to the apex. Drupe 

 1 -seeded (f. 106. f.); seeds angular. Albumen fleshy or want- 

 ing. Embryo linear, straight, central. Cotyledons linear, flat, 

 leafy. Radicle superior, straight, terete, pointing towards the 

 hylum, with an inconspicuous plumule. Trees and shrubs with 

 the younger branches compressed, and usually covered with im- 

 bricate scales (f. 106.). Stipulas axillary, concave. Leaves 

 alternate, rarely opposite, quite entire, smooth in most parts of 

 the species and perhaps in all. Pedicels angular, gradually 

 thickened. Flowers solitary, twin, or in fascicles, rising from 

 axils of stipulaceous scales, small, white, or yellowish-green. 

 This order has been separated by Kunth from Malpighiaceee, on 

 account of the petals being appendiculate, from the seeds being 

 albuminous, and in the fruit being 1-celled from abortion, as 

 well as from its peculiar habit. It differs from all the neigh- 

 bouring orders in the appendiculate petals. From Marcgravia- 

 cece, Guttiferce, &c. in the leaves being stipulate. 



Synopsis of the Genera. 



1 ERYTHRO'XYLON. Calyx 5-parted, 5-angled at the base. 

 Styles 3, distinct. 



2 SE'THIA. Calyx 5-lobed. Styles 3, but joined together in 

 one. Stigmas distinct. 



I. ERYTHRO'XYLON (from pv0po E , erythros, red, and 

 ,v\ov, xylon, wood ; the wood of the trees is not red, as the 

 name would imply, but the juice of the fruit is red). Lin. gen. 

 no. 575. Cav. diss. 8. p. 399. Lam. ill. t. 383. H. B. et 

 Kunth, 1. c. D. C. prod. 1. p. 573. 



LIN. SYST. Monadelphia, Dec&ndria. Calyx 5-parted, 5- 

 angled at the very base. Styles 3 (f. 106. d.), unconnected to 

 the base, not joined as in Sethia. 



1. Penninervia (from penna, a feather, and nervus, a 

 nerve or sinew ; the nerves of the leaves are disposed in the man- 

 ner of the feathers of a pen). Leaves feather-nerved ((. 106. g.), 

 nith the nerves small, conniving at the apex.
