Viburnum. RUBIACEiE 19 



shall's account entire, and commend this obscure species to the botanists of 

 Kentucky, Tennessee, &c. " This grows naturally in Carolina and other 

 parts of America; risino- with a shrubby stalk to the height of 8 or 10 feet, 

 covered with a smooth purplish bark, and divided into several branches. 

 The leaves are heart-shaped, oval, sharp-pointed, deeply sawed on their 

 edges, strongly veined, and placed opposite on slender foot-stalks. The 

 flowers are collected in large cymes or umbels at the ends of the branches ; 

 those ranged on the border are male, but the centre is filled with hermaphro- 

 dite flowers, which are succeeded by pretty large oval berries, red-colored 

 when rips." Marsh, arbust. Amer. p. 162. 



Order LXXIII. RUBIACE.E. Juss. 



Tube of the calyx adherent to the ovary, or rarely partly or almost 

 completely free ; the limb mostly 4-5-cleft or toothed, sometimes ob- 

 solete. Corolla inserted upon the summit of the calyx-tube, com- 

 posed of as many united petals as there are lobes of the calyx, valvate, 

 imbricate, or somewhat contorted in aestivation. Stamens inserted 

 into the tube of the corolla, equal in number and alternate with its 

 lobes (or very rarely fewer) : anthers introrse. Ovary 2-(rarely 3- 

 several-) celled, with 1-many ovules in each cell : style single or part- 

 ly divided : stigmas distinct or concrete. Fruit capsular, drupaceous, 

 baccate, or separable into indehiscent carpels. Seeds anatropous or 

 amphitropous, solitary, few, or numerous in each cell. Embryo 

 straight or slightly curved, in the axis or at the extremity of copious 

 densely fleshy or horny albumen — Trees, shrubs, or herbs, with op- 

 posite, or rarely verticillate, entire leaves. Stipules between the pe- 

 tioles, sometimes simulating the leaves. Flowers regular. Inflores- 

 cence various. 



Suborder I. STELLATE. R. Br. 



Leaves apparently (perhaps really ?) verticillate ; but the whorls 

 generally supposed to consist of a pair of leaves and 1 to 3 leaf-shaped 

 stipules on each side, which however are only to be distinguished from 

 true leaves by their never bearing buds in their axils. Ji^stivation of 

 the corolla valvate. Ovary entirely coherent with the tube of the 

 calyx. Fruit consisting of 2 united indehiscent (dry or baccate) 1- 

 seeded carpels. — Herbs, or rarely sufTruticose plants, chiefly natives of 

 temperate or cold regions.
