DiERViLLA. CAPRIFOLIACE^. 11 



tinctions. We know not whether Mr. Brown was acquainted with these differences 

 when he united Weigela to Diervilla, or whether he would consider them of generic 

 importance. It must be remarked that both the elder and the younger De Candolle 

 have, by some misapprehension, described the capsule of Diervilla as one-celled or 

 half2-celled; while Jussieu and some other botanists consider it 4-celled, an easy 

 mistake, since the placentae often reach nearly or quite to the back of each cell. 



§ Flowers yellouish: cajjsule membranaceous : seeds not furnished with a crest 

 or wing ; the testa crustaceous. — Diervilla proper.

 glabrous, or somewhat hairy on the veins beneath ; peduncles l-3-(mostIy

Rocky woods, Canada ! and from Newfoundland ! and Hudson's Bay to 

 the Rocky Mountains, Northern and Middle States ! and along the higher 

 mountains to Carolina. (3. On the Black Mountains, North Carolina, Mr. 

 M. A. Curtis ! — May-June. Stem 2-4 feet high, branched. Leaves 2-4 

 inches long. Peduncles from the axils of the upper leaves, rather longer than 

 the petioles : the central flower sessile, the lateral ones pedicellate. Bracte- 

 oles subulate, shorter than the ovary. Corolla greenish-yellow, about three- 

 fourths of an inch long, somewhat irregular ; the lobes oblong. Stamens 

 and style exserted. Capsule ovoid-oblong, slightly angled, appearing al- 

 most 4-celled by the projection of the placentfe ; the summit tapering 

 abruptly into a long and narrow neck, and crowned with the apparently per- 

 sistent teeth of the calyx. — Bush-Honeysuckle. — We should have hardly ven- 

 tured, perhaps, to restore the prior name of Moench (although it is a very 

 good one), had we found any thing like uniformity among botanists in the 

 adoption of some one among the later names. 



Subtribe 2. Trioste^:. — Fruit drupaceous ; the endocarp bony. Testa 

 of the seed membranaceous. 



5. TRIOSTEUM. Linn. ; Gartn. fr. t. 26; Lam. ill. t. 150. 



Calyx-tube ovoid ; the segments of the 5-parted limb linear-lanceolate, fo- 

 liaceous, persistent. Corolla tubular, gibbous at the base, somewhat equally 

 6-lobed, a little longer than the calyx. Stamens 5, included. Ovary 3- 

 (rarely 4-5-) celled, with a single anatropous ovule suspended from the sum- 

 mit of each cell: style included : stigma capitate, somewhat 3-lobed. Fruit 

 drupaceous, rather dry, roundish-obovoid, obscurely 3-(5-) sided, containing 

 as many ribbed elliptical bony nucules. Testa membranaceous. Embryo 

 minute, oblong, in the axis of fleshy albumen. — Perennial herbaceous or rare- 

 ly sufFrutescent plants (natives of the United States and the mountains of 

 Middle Asia) ; the lanceolate or oval entire leaves narrowed and somewhat 

 connate at the base. Flowers axillary and sessile or nearly so, solitary or
