38 ERICACEAE. Kalmia. 



upward, the salient keels running to the apex of the lobes and to the sinuses, the 

 limb imbricated in the bud. Anthers free and on erect filaments in the early 

 bud, in the full-grown bud received in the pouches of the corolla, and the fila- 

 ments bent over as the corolla enlarges, and still more when it expands, straight- 

 ening elastically and incurving when disengaged, thereby throwing out the pollen : 

 anther-cells opening by a large pore, sometimes extending into a chink. Stigma 

 depressed. Capsule globular, o-celled : placentas pendulous or porrect from the 

 upper part of a small columella. Seeds with a thin and mostly close coat. 



1. Flowers in simple or clustered umbels, fascicles, or corymbs : calyx per- 

 sistent under the capsule : leaves and branches glabrous or nearly so. 



*= Inflorescence compound : branchlets terete : capsule depressed, tardily septicidal : seeds oblong. 

 K. latifolia, L. (LAUREL, CALICO-BUSH, &c.) Widely branching shrub 3 to 10, or in 

 S. Alleghanies even 30 feet high, with very hard wood : leaves alternate or occasionally 

 somewhat in pairs or threes, oblong or elliptical-lanceolate, acute or acutish at both ends, 

 petioled, bright green : inflorescence very viscid-pubescent : flowers produced in early sum- 

 mer; the corymbose fascicles numerous and crowded in compound terminal corymbs: 

 corolla rose-color to white, viscid, three-fourths inch in diameter : capsules viscid-glandular ; 

 the almost closed valves .or pieces generally carrying with them the placentae. Sims, 

 Bot. Mag. t. 175 ; Schk. Handb. t. 110; Michx. f. Sylr. ii. t. 68; Bigel. Med. Bot. i. 133, 

 t. 13. (Catesb. Car. ii. t. 98; Trew, Ehrct. t. 38.) Rocky hills or northward in damp 

 grounds, commonly where wooded, Canada, Maine to Ohio and Tennessee, and chiefly 

 along the mountains to W. Florida. 



K. angustifolia, L. (SHEEP LAUREL, LAMBKILL, WICKY.) Shrub 2 or 3 feet high, 

 simple : leaves mostly in pairs or threes, oblong, obtuse, petioled, an inch or two long, light 

 green above, dull or pale beneath : inflorescence lateral from the early growth of the ter- 

 minal shoot, puberulent, slightly glandular: flowers in early summer, not half as large as 

 in the foregoing, purple or crimson: capsules not glandular, on recurved pedicels. Sims, 

 Bot. Mag. t. 331. (Catesb. Car. iii. t. 17; Trew, Ehret. t. 18.) Hillsides, Newfoundland 

 and Hudson's Bay to the upper part of Georgia. 



K. CUneata, Michx. Low shrub, somewhat pubescent : leaves oblong with cuneate 

 base, almost sessile and chiefly alternate, mucronate (an inch long) : inflorescence lateral, 

 few-flowered, nearly glabrous: sepals ovate, obtuse: corolla white or whitish, one-third 

 inch in diameter. Fl. i. 257; Nutt. Gen. i. 268; Loud. Arb. fig. 1143. Swamps, eastern 

 part of N. & S. Carolina (not in the mountains, as said Pursh) : little knpwn. 



* * Inflorescence a simple terminal umbel or corymb : branchlets 2-edged : capsule ovoid-globose, 

 freelv dehiscent from the summit; the valves 2-cleft at apex ; placenta? left on the summit of the 

 columella: seeds linear, with a loose cellular coat. 



K.. glaiica, Ait. Shrub a foot or two high, wholly glabrous, mostly glaucous : leaves all 

 opposite or rarely in threes, almost sessile, oblong or linear-oblong, or appearing narrower 

 by the usual strong revolution of the edges, glaucous-white beneath (an inch or less long) : 

 flowers in spring, lilac-purple, half to two-thirds inch in diameter : bracts large : sepals 

 ovate, scarious-coriaceous, much imbricated. Hort. Kew. ed. 1, ii. 64, t. 8 ; Sims, Bot. 

 Mag. 1. 177 ; Lodd. Cab. t. 1508. A", polifolia, Wang. Act. Nat. Ber. v. t. 5. Var. rosmarini- 

 folia, Pursh, is merely a state with very revolute leaves : var. microphylla, Hook. Fl. a small 

 alpine form, a span high, with leaves barely half inch long. Bogs, Newfoundland and 

 Hudson's Bay to Pennsylvania, and on the western coast at Sitka, &c., extending down 

 the Rocky Mountains to Colorado, and down the Sierra Nevada to Mt. Dana, California, 

 in the depauperate alpine form or variety. 



2. Flowers mostly scattered and solitary in the axils of ordinary leaves ; 

 these small and, with the branches and foliaceous sepals, hirsute : capsule shorter 

 than the calyx : placentae remaining upon the columella : seeds oval or roundish, 

 and with a close and firmer coat. (The Cuban K. ericoides, with rigid Heath-like 

 leaves, has inflorescence approaching the first section, and sepals apparently per- 

 sistent.)
