1G2 CALYCANTHACE^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. (Ameluncier 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. Botryapilim ; 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 w r hen young ; racemes and petals shorter. 



Var. rotundifblia ; 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. CAL,Y€AlVTHACEiE. (Calycanthus Family.) 



Shrubs v)ith opposite entire leaves, no stipules, the sepals and petals similar 

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

 the fruit like 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, mostly 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.
