FIGWORT FAMILY. SCOPHULARIACE/E Lindl. 



This family consists cliiefly of herbs, but some shrubs and trees, and is of very wide dis- 

 tribution. About 2,.j00 species are Ifuown, grouped in Kxi genera. 



. J, -pci'f'S various, without stipules. Floicers mostly perfect, complete and irregular: calyx 

 inferior, variously cleft or divided, persistent; corolla gamopetalous, irregular, v^-ith imbricated 

 lobes ; stamens 2-.5, didynamous or nearly equal and inserted on the corolla alternate with its 

 lobes : anthers 2 or 1-celled : pistil solitary with slender style, entire or 2-lobed stigma and 

 mostly 2-celled ovary containing anatropous or amphitropous ovules on axile placentas. Fruit 

 a capsule usually containing numerous seeds with small embryo in copious albumen. 



THE PAULOWNIA. Genus PAULOWNIA Sieb. & Zucc. 



This is a genus composed of possibly two or three species of Asiatic trees but is generally 

 known only by the single species P. iniperUilis S. & Z., now naturalized in America. 



Leaven opposite, long-petioled, mostly .5-8 in. long larger on vigorous shoots, broad-ovate, 

 cordate, acute or short acuminate, entire or with a single short-pointed lobe on each side, vel- 

 vety pubescent especially at first ; long-petioled, branchlets with segmented pith. Floirrrn 

 before or with the leaves, fragrant, in large erect rusty tomentose terminal panicles from buds 

 formed the previous summer and remaining naked during the winter ; calyx with ') thick lobes ; 

 corolla l%-2 in. long, jjale violet or blue, somewhat irregular, with ~t spreading lobes, puberu- 

 lent outside: stamens 4, didynamous, included, with divaricate anther-sacs. Fruit broad-ovoid 

 woody abruptly pointed 2-celled capsule, about 1% in. long, loculicidally dehiscent and contain- 

 ing many small membranous-winged seeds. 



The genus is named after Princess Anna Paulowna, daughter cf the Czar Paul I.

HONEYSUCKLE FAMILY. CAPRIFOLIACE^ Bent. 



Trees, shrubs, vines, and perennial herbs of about 2(50 species and grouped in ten genera. 



They are most abundant in the north temperate zone, but a few extend into the tropics and 



the southern hemisphere. 



Leaves opposite, petiolate, involute in the bud and mostly without stipules. Flotpers regu- 

 lar, perfect, and in terminal compound cymes; calyx-tube adnate to the ovary with .5-toothed 

 limb : corolla .5-lobed and sometimes 2-lipped : stamens .5, inserted on the tube of the corolla 

 and alternate with its lobes, exserted, with slender free filaments ; anthers oblong, introrso, 

 2-celled, longitudinally dehiscent; ovary inferior, l-(j-celled with short style and 3-5-lobed capi- 

 tate stigma : ovules solitary, anatropous and suspended from the apex of the cell. Fruit a. 

 1-6-celled drupe, capsule or berry ; seeds with membranous coat, minute embryo and copious 

 albumen. 



THE NANNY-BEREIES, ETC. Genus VIBURXUM L. 



Shrubs and small trees with tough branches of nearly 100 species widely distributed in 

 north temperate regions and a few in the tropics. Several species are important on account 

 of their ornamental flowers and fruit. About 75 are natives of North America, all shrubby 

 except three, which are small trees of the Atlantic states. 



Leaves deciduous, generally without stipules and the first pair rudimentary: petioles 

 broad; buds large and enveloped with a single pair of scales. Floircrs white or rarely pink, 

 in terminal or axillary compound cymes with minute caducous bracts and bractlets, the outer 

 flowers sometimes radiant and neutral : calyx with tubinate tube and stout .^-toothed limb, 

 persistent in the fruit : corolla rotate with ."i spreading and finally reflexed lobes : ovary 1-celled, 

 inferior, with short conical style, 3-lobed and stigmatic at apex. Fruit an oblong or sub- 

 globose and sometimes flattened drupe with thin sweet or acidulous flesh and a single stone 

 which in the American species is dark brown, coriaceous and much flattened. 



The name is ancient Latin name of one of the European species.
