162 CALYCANTHACE^. (CALYCANTHUS FAMILY.) 



P. AucupARiA, Gasrtn., 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. (Amdancier is the popular name of A. vulgaris in Savoy.) 



1. A. Canad6nsis, 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 Botryapiurfi, Willd.) 



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

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



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

 variety ; racemes 6 - 10-flowered. 



Var. alnifblia ; 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,YCAIVTHACE^E. (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 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 mart y 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 Hose; but the enlarged hip dry when ripe, enclosing the achenia.
