2. A. oligocárpa, Roem. A low shrub 2--4° high, soon glabrous; leaves thin, _oblong, acute at both ends, finely serrate_, 1--2´ long; _flowers few_ (1--4), rather long-pedicelled; _petals oblong-obovate; fruit broad-pyriform_, dark purple with a dense bloom. (A. Canadensis, var. oligocarpa, _Torr. & Gray_.)--Cold swamps and mountain bogs; Lab. to northern N. Eng. and N. Y., and the shores of Lake Superior. 3. A. alnifòlia, Nutt. A shrub 3--8° high, usually glabrate or nearly so; leaves _somewhat glaucous_ and thickish, _broadly elliptical or roundish_, very _obtuse or rarely acute_, often subcordate at base, _coarsely toothed toward the summit_, ½--2´ long; raceme short and rather dense; petals cuneate-oblong, 3--8´´ long; fruit globose, purple. (A. Canadensis, var. alnifolia, _Torr. & Gray_.)--A western mountain species, which occurs in Minn. and N. Mich., and which the broad-leaved form of A. Canadensis sometimes closely simulates. ORDER 34. CALYCANTHÀCEÆ. (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. CALYCÁNTHUS, 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 achenes.--The lurid purple flowers terminating the leafy branches. Bark and foliage aromatic; the crushed flowers exhaling more or less the fragrance of strawberries. (Name composed of κάλυξ, _a cup_ or _calyx_, and άνθος, _flower_, from the closed cup which contains the pistils.) 1. C. flóridus, L. _Leaves oval, soft-downy underneath_.--Virginia(?) and southward, on hillsides in rich soil. Common in gardens. April--Aug. 2. C. lævigàtus, Willd. _Leaves oblong_, thin, either blunt or taper-pointed, _bright green and glabrous_ or nearly so on both sides, or rather pale beneath; flowers smaller.--Mountains of Franklin Co., Penn. (_Prof. Porter_), and southward along the Alleghanies. May--Aug. 3. C. glaùcus, Willd. _Leaves_ oblong-ovate or ovate-lanceolate, _conspicuously taper-pointed, glaucous-white beneath_, roughish above, glabrous, large (4--7´ long), probably a variety of the preceding.--Virginia (?) near the mountains and southward. May--Aug. ORDER 35. SAXIFRAGÀCEÆ. (SAXIFRAGE FAMILY.)
