162 CALYCANTIIACE^E. (CALYCANTHUS FAMILY.) 



P. aucuparia, Gaertn., the European Mountain Ash or Rowan-tree, 

 the one more commonly planted in grounds : it has paler, oblong, and obtuse 

 leaflets, their lower surface downy, larger globose berries, and blunter and 

 tomentose leaf-buds. 



18. AMELANCHIER, Medic. June-berry. 



Calyx 5-cleft. Petals oblong, elongated. Stamens numerous, short. Styles 

 5, united below. Ovary 5-celled, each cell 2-ovuled ; but a projection grows 

 from the back of each, and forms a false partition ; the berry-like pome thus 

 10-celled, with one seed in each cell (when all ripen) : partitions cartilaginous. 



— Small trees or shrubs, with simple sharply serrated leaves, and white flowers 

 in racemes. (Amelancier is the popular name of A. vulgaris in Savoy.) 



1. A. Canadensis, Torr. & Gray. (Shad-bush. Service-berry.) 

 Calyx-lobes triangular-lance-form ; fruit globular, purplish, edible (sweet, ripe 

 in June). — Along streams, &c. : common, especially northward. April, May. 



— Varies exceedingly; the leading forms are, — 



Var. Botryapium; a tree 10° -30° high, nearly or soon glabrous; leaves 

 ovate-oblong, sometimes heart-shaped to the base, pointed, very sharply serrate ; 

 flowers in long drooping racemes ; the oblong petals 4 times the length of the 

 calyx. (Pyrus Botryapium, Willd. ) 



Var. oblongifblia ; a smaller tree or shrub ; leaves oblong, beneath, like 

 the branchlets white downy when young ; racemes and petals shorter. 



Var. rotundif61ia ; with broader leaves and smaller petals than in the first 

 variety ; racemes 6 - 10-flowered. 



Var. alnifdlia ; shrub, with the roundish leaves blunt or notched at both 

 ends, serrate towards the summit ; racemes dense and many-flowered. — Chiefly 

 in the Western States and westward. 



Var. oligocarpa ; shrub, with thin and smooth narrowly oblong leaves, 

 and 2-4-flowered racemes, the broader petals scarcely thrice the length of the 

 calyx. — Cold and deep mountain swamps, northward. 



Order 34. CAEYCANTHACEiE. (Calycanthus Family.) 



Shrubs with opposite entire leaves, no stipules, the sepals and petals similar 

 and indefinite, the anthers adnate and extrorse, and the cotyledons convolute : 

 the fruit lite a rose-hip. Chiefly represented by the genus 



1. CALYCANTHUS, L. Carolina Allspice. Sweet- 

 Scented Shrub. 



Calyx of many sepals, united below into a fleshy inversely conical cup (with 

 some leaf-like bractlets growing from it) ; the lobes lanceolate, mostby colored 

 like the petals ; which are similar, in many rows, thickish, inserted on the top 

 of the closed calyx-tube. Stamens numerous, inserted just within the petals, 

 short; some of the inner ones sterile (destitute of anthers). Pistils several or 

 many, enclosed in the calyx-tube, inserted on its base and inner face, resembling 

 those of the Rose ; but the enlarged hip dry when ripe, enclosing the acheuia.
