western part of Georgia ; and of North Carolina, on the Catabaw 

 Mountains. The large leaves punctated on their under side, 

 with rough tubercles and other marks, give sufficient reason for 

 considering it a distinct species.

 10 to 12 feet. 



3 H. PE'RSICA (D. C. prod. 4. p. 268.) leaves oval, acumi- 

 nated, repandly toothed above, cuneated at the base, equal, t? . 

 H. Native of Persia, in the province of Lenkeran, where it 

 was collected by Hansen. Adult leaves rather scabrous on the 

 nerves and petioles ; the rest glabrous. Flowers unknown.

 near Nankin, and in the island of Cheusan. Pluk. amalth. 32. 

 t. 368. f. 2. Petals linear, 3-nerved, very much elongated. 

 Anthers with deciduous valves; hence it is proposed by R. Br. 

 to form it into a distinct section under the name of Loropetalum. 



China Witch-hazel. Shrub 6 to 10 feet. 



Cult. The species of Witch-hazel are well adapted for shrub- 

 beries ; they will grow in any common soil, and are increased by 

 layers or suckers.

 of Madagascar, near Foulpointe. Pet. Th. 1. c. D. Thouarsii, 

 Roem. et Schultes, syst. 3. p. 485. 



Stipulate-\ea.ved Dicoryphe. Shrub. 



Cult. A mixture of sand, loam, and peat will be a good soil 

 for this plant ; and young cuttings will strike root in sand under 

 a hand-glass, in heat. 



III. TRICHO'CLADUS (from Opt rp<xc> thrix trichos, a 

 hair, and KAaSoe, klados, a branch ; the branches are clothed 

 with stellate hairs). Pers. ench. 2. p. 597. D. C. prod. 4. p.

LIN. SYST. Dioecia, Mondndria. Flowers dioecious. Scales 

 paleaceous, distinguished from the capitate flowers. Male 

 flowers. Calyx unknown. Petal 1, convolute. Stamen 1, near 

 the scale and the petal ; anthers ovate, double celled from the 

 connate filaments (Thunb.), valves dehiscent (Burch.). Female 

 flowers. Calyx unknown. Petals wanting. Ovarium villous. 



Style 1. Capsule ovate, 4-valved, 4-celled. Arillus (seed, 

 Thunb.) ovate, glabrous, villous from stellate dots. Leaves op- 

 posite, petiolate, oval, acuminated, entire. Flowers in terminal 

 heads, crowded on a common receptacle. The character is 

 taken from the description of the tree by Thunberg. 



1 T. CRINITUS (Pers. 1. c.) Pj . G. Native of the Cape of 

 Good Hope, in the woods of Houtniquas. Dahlia crinita, Thunb. 

 11. cc. and fl. cap. 1. The shrub has the resemblance of a species 

 of Crbton.
