Monarda. LABIATE. 375 



M. Russelliana, Nutt. Slender, sparingly pubescent : leaves lanceolate or narrowly 

 ovate-lanceolate from a rounded or subcordate base: calyx naked at orifice ; its slender- 

 subulate teeth muricate-glandular : corolla nearly glabrous, slender, with long and, much 

 exserted tube ; lower lip shorter, obscurely 3-lobed at the extremity. Trav. Arkans. & 

 Trans. Am. Phil. Soc. n. ser. v. 185 ; Hook. Bot. Mag. t. 2513 & Exot. Fl. t. 130 ; Sweet, 

 Brit. Fl. Card. t. 166. Arkansas, Nutlall, T. L. Harvey. 



2. CHEILYCTIS, Benth. Heads (i. e. verticillastrate glomerules) commonly 

 in the axils of all the upper pairs of leaves, or interrupted-spicate, foliose-brac- 

 teate : upper face of the floral leaves and larger bracts often canescent and some- 

 times purple-tinged : corolla with shorter almost included tube, more dilated throat, 

 and oblong lips ; the upper arching, emarginate or cleft at apex (either sparsely 

 bearded or glabrous in the same species), seldom at all surpassed by the stamens ; 

 lower with middle lobe often broadest : leaves lanceolate or oblong, sparsely ser- 

 rate or denticulate, tapering into the petiole : minute pubescence more or less 

 cinereous. Clieilyctis, Raf. Monarda Coryanthus, Nutt. 



* Corolla yellowish with copious brown-purple spots : calyx-teeth lanceolate- or triangular-subulate : 

 floral leaves and involucrale bracts mostly muticous: root perennial. 



M. punctata, L. (HORSE-MINT.) Stem commonly 2 feet high: floral leaves and bracts 

 (either whitened or purplish or both) often slender-acuminate : calyx-teeth rigid, soon stellate- 

 spreading, hardly longer than the width of the villous orifice of the tube. Spec. i. 22 ; 

 Andr. Bot. Rep. t. 546; Bot. Reg. t. 87. M. Intca, Michx. Fl. i. 16. Sandy ground, New 

 York to Wisconsin, and south to Florida and Texas. Varies in foliage, pubescence, &c., 

 passing into 



Var. lasiodonta, Gray, 1. c., with throat and teeth of calyx densely villous : plant 

 sometimes robust, of ten smaller, and narrow-leaved. Texas, Dnunmond. New Mexico and 

 Arizona, Wislizenus, Wooodliouse, Rothrock. 



* * Corolla white or pinkish, not spotted, but more or less punctate: calvx-teeth aristifonn or 

 subulate-setaceous: iuvolucral bracts conspicuously aristate-tipped: root annual. 



M. pectinata, Nutt. Rather low and slender: floral leaves and bracts of the compara- 

 tively small heads mostly green; the latter oblong, short-aristate, obscurely 3-nervcd, hir- 

 Bute-ciliate : calyx-teeth subulate-setaceous from a broad base, soon spreading, villous-hir- 

 sute within, twice the length of the width of the very villous orifice. PI. Gamb. 182. 

 M. citriodora, var. aristidata, Gray, Proc. Am. Acad. viii. 369, in part, where Nuttall's name 

 was inadvertently written " M. penicil/ata." New Mexico, near Santa Fe', Gambd. Not 

 since seen. Seemingly a hybrid between M. punctata and M. citriodora. 



M. dinopodioid.es. Slender, a foot or more high : bracts of the rather small heads 

 mostly green or greenish, erect, oblong-ovate to obovate-lanceolate, rigid, strongly 3-5- 

 nerved, hispid-ciliate : calyx-teeth always erect, rigid, aristiform-attenuate (tapering grad- 

 ually from the base), fully two-thirds the length of the hirsute tube, purplish, sparsely 

 hispid; throat densely short-villous. M. aristata, Hook. Bot. Mag. t. 3526, not Nutt. M. 

 citriodora, var. aristidata, Gray, 1. c., in part. Texas, Drummond, Wriyht, Reve.rchon. 



M. citriodora, Cerv. Usually more robust, the larger forms (2 or 3 feet high) with the 

 aspect of M. /ntnctata : bracts narrowly oblong, similarly whitened or purple-tinged, at 

 least their spreading or recurving and abruptly aristulate or slender aristate tips : throat 

 of the calyx densely villous ; the teetli slender-aristiform, at length usually spreading, 

 half or two-thirds the length of the mostly glabrous tube, from sparsely hirsute-plumose 

 with long soft hairs to naked. Cervantes in Lag. Nov. Gen. & Spec. 2 (1810) ; Gray, 1. c., 

 the \ar.tenui-aristata. M. aristata, Nutt. in Trans. Am. Phil. Soc. n. ser. v. 186; Benth. 

 Lab. 318, & DC. I. c. 363 : excl. the char, of the calyx-teeth at the close, which was taken 

 from M. punctata, var. lasiodonta. Plains of Nebraska to Texas, Eastern Colorado, and 

 Arizona. (Mex.) 

 M. GRAcins, Pursh, Fl. i. 17, described from a specimen in Lyon's herbarium, said to 



come from the mountains of South Carolina (to which Virginia and the accustomed v. v. are 



added by Pursh), is not identified by the description. It may not improbably be Pycnanthe- 



muni montanum, Michx.
