 banks, along tiie Alleghanies from Virginia and E. Kentucky to Georgia. 



* * * Long (iliform style declined and upwardly curved, much exceeding the rotate corolla : cap- 

 sule ()blong-clavate, sessile, erect; the openings close to the summit: inliorescence truly spicate 

 (centripetal) : root annual or at most biennial. 



C. Americana, L. Sparsely hairy or almost glabrous : stem mostly simple, a yard or 

 two high : leaves thin and large, ovate and ovate-lanceolate or the lowest cordate, petioled ; 

 upper passing into bracts of the elongated and loosely many-flowered virgate spike : corolla

 C lUinoensis, Fresenius, a branched state with paniculate leafy spikes, which is not uncom- 

 mon. — Shaded low ground, W. New York to Iowa, south to Georgia and Arkansas. 

 C. PLANiFLOKA, Lam. (C. nitida, Ait.), long ago described from cultivated specimens, 



vaguely attributed to North America, is wholly unknown in the wild state ; apparently allied 



to C. persicajolia, L., and not N. American.

H. rariflorum, Nutt. A delicate little annual, sparsely hirsute : stems filiform, diffusely 

 sjircading, leafy, branching : leaves orbicular with cordate partly clasping base (a fourth 

 to half inch long), coarsely many-toothed : flowers solitary, terminal and lateral, also axil- 

 lary ; the later ones only with well-developed pale blue corolla, which barely exceeds the 

 ovate and sparingly toothed foliaceous calyx-lobes ; these one to three lines long. — Shady

Order LXXVII. ERICACEAE. 



Trees, shrubs, or some perennial herbs, with simple and undivided leaves des- 

 titute of stipules and commonly alternate, synnnetrical (4-5-merous) and perfect 

 flowers, either regular or occasionally irregular, stamens free or nearly free from 

 the corolla and as many or more commonly twice as many as its lobes or petals, 

 tlie anthers 2-celled and in most opening by pores (in many awned or otherwise 

 appendaged), the pollen composed of 4 united grains (except in the fourth suborder 

 and a part of the third), and the style single. Calyx imbricated or sometimes 

 valvate hi the bud, free and the corolla and stamens hypogynous, excejit in the 

 first suborder. Corolla not rarely 5- (or 4-) petalous, in the bud itribricated or in 

 some convolute. Anthers introrse, or in the Pyrolinece primarily and normally 

 extrorse, but in anthesis introrsely inverted! Ovary 4-lO-celled (or the cells 

 rarely 3 or 2 and fewer than the petals), with placentai in the axis (a tribe of 

 Monotropece excei)ted) ; the ovules numerous, generally very numerous, sometimes 

 solitary, anatropous. Stigma not rarely girt with a ring, entire or merely lobed ; 

 only in Clethra is the apex of the style o-cleft. P'ruit capsular, baccate, or dru- 

 paceous. F^mbryo small or minute, in fleshy albumen ; the cot^'ledons small and 

 short or undeveloped. [Ericacece, Vacciniacece, Pyrolacecc, & Monotropece of 

 authors, ail merging into one large family.) 



SuBORDKR I. VACCINIE^. Calyx-tube adnate to the ovary (or to the 

 greater part of it), which in fruit is baccate, either a true berry or drupaceous, 

 crowned with the calyx-teeth. Corolla always gamopetalous, and with the disk
