This plant nearly corresponds with a specimen labelled " A. arborea, P. Th. ?," in the 

 Thouarsian herbarium at the Jardin des Plantes. Excepting in the smaller flowers, more 

 ovate petals, and staminal tube not produced above the insertion of the filaments, it is very 

 near to A. dentata. 



10. A. castaneoides, Welw. mss. A robust shrub, attaining 6-8 ft. ; 

 the extremities shortly pilose or pubescent with spreading hairs. Leaves ob- 

 ovate- or oblanceolate-oblong, cuspidate or shortly acuminate, narrowed to 

 the rounded obtuse or subcordate base, dentate-serrate especially above the 

 middle, glabrescent above, the midrib distinctly pubescent at first, softly 

 but very shortly pubescent beneath, usually 5-8 in. long, 2-2f in. broad 

 above the middle ; petioles from 2-3 lines to an inch or more. Flowers 

 yellowish, in terminal corymbose or pyramidal panicles, 3-5 in. long and 

 broad ; the lower branches longest. Pedicels shorter than or scarcely exceed- 

 ing the calyx. Sepals ovate obtuse. Petals ovate-oblong, obtuse, plane or 

 slightly recurved towards the apex. Staminal tube very shortly produced 

 above the insertion of the anthers. Appendix of anterior anther-cells entire 

 or 2 -fid. Ovary slightly pubescent. Young fruit globose, glabrous; the 

 style long-persisting.

Var. ? strictiflora, a shrub of 4 ft., with strict glabrescent branches ; flowers smaller, 

 white, in short, erect, terminal and axillary, cymose panicles.

This may prove a distinct species, but our material does not suffice to determine. 



11. A. dentata, P. de Beam. Fl. d'Owar. ii. 11. t. fi5 (Ceranthera)- 

 A shrub from 3-4 to 10-15 ft. in height; the extremities glabrous or mi-

 serrate or serrulate, glabrous above, nerves beneath shortly pilose or gla- 

 brate ; 4-8 (3-9) in. long, 2-3 in. broad ; petioles £-£ in. or shorter. 

 Flowers whitish or sulphur-yellow, recurved or subpendulous, in terminal 

 racemose or pyramidal panicles shorter than or exceeding the leaves, usually 

 from 2-4 in. long. Lower branches of the panicle ascending, short or elon- 

 gate. Pedicels shorter than or equalling the calyx. Sepals oblong-ovate, 

 rather acute. Staminal tube produced above the insertion of the anthers. 

 Connective ovate, obtuse. Anterior anther-cells with a 2-partite tip. Valves 

 of the fruit pointed, with a horny endocarp. Seeds 2-3 lines long ana 

 broad, smooth.

 Perhaps this ought to include also A. subintegrifolia.
