596 LABI AT JE. Calamintha. 



7. CALAMINTHA, Mcench. CALAMINTH. 



Calyx oblong or tubular, often gibbous, about 13-striate, bilabiate; the upper lip 

 3-toothed or 3-cleft ; lower 3-parted ; the throat either naked or bearded. Corolla 

 with a straight tube mostly exceeding the calyx, an enlarging throat, and a distinctly 

 bilabiate limb ; upper lip erect, flattish or concave, entire or emarginate, the lower 

 spreading, 3-lobed or parted. Stamens 4 ; the upper pair sometimes smaller and 

 sterile : filaments ascending parallel under or beyond the upper lip, or conniving in 

 pairs : anthers 2-celled, with or without a thickened connective. Herbs or some- 

 what suffruticose plants, of various habit, forming four or five very distinct sections ; 

 the species dispersed around the northern hemisphere. 



C. PALMKRI, Gray, is a new species of the Acinos section, a low and small-flowered annual, 

 with wholly the aspect of a Hedeoma. It was recently discovered on Guadalupe Island off Lower 

 California, by Dr. E. Palmer. 



1. C. niimuloides, Benth. Erect, 2 feet high, somewhat viscidly villous : 

 leaves ovate, thin, coarsely serrate, an inch or two in length, slender-petioled: flowers 

 nearly solitary in the axils ; their slender peduncle leafy-bracteate at the base : calyx 

 tubular, two thirds of an inch long, nearly naked in the throat, barely bilabiate, 

 the three teeth of the upper lip united higher than the two lower, all cuspidate 

 from a broadly triangular base : corolla orange, an inch and a half long, its cylin- 

 drical tube twice the length of the calyx. PL Hartw. 331. 



Shady places, Carmel River, Monterey Co., Hartweg. 



2. C. (?) ilicifolia, Gray. Annual, branched from the base, 3 to 6 inches high, 

 rigid, puberulent or glabrate : leaves coriaceous, ovate-spatulate or cuneate, coarsely 

 few-toothed, about half an inch long and with a petiole of equal length : bracts 

 nearly as large as the leaves, but 'closely sessile, rigid-coriaceous, broadly ovate or 

 roundish, callous-margined ; the stout midrib and 3 or 4 pairs of pinnate divaricate 

 veins projecting into long prickles : flowers several and sessile in each axillary 

 cluster, each pair of clusters (making a false whorl) involucrate by 4 bracts : calyx 

 oblong, villous-pubescent, moderately bilabiate ; the teeth spinulose-subulate from a 

 broad base : corolla apparently purplish or white (half an inch long) ; the tube twice 

 the length of the calyx ; upper lip erect, oblong and concave, entire ; the lower broad 

 and spreading, 3-lobed ; the lobes short and rounded ; middle one deeply and the 

 lateral ones slightly emarginate : stamens inserted high in the enlarged throat ; 

 the pairs very unequal ; anterior pair with stout filaments and divaricate almost 

 confluent anthers ; posterior pair with slender filaments and much smaller or abor- 

 tive anthers. Proc. Am. Acad. viii. 368. 



California, Major Rich, in herb. Torrey. Near San Diego, D. Cleveland. Described as consti- 

 tuting a peculiar section, ACANTHOMINTHA. Additional specimens, from Mr. Cleveland, show 

 abortive anthers to the upper pair of stamens (and no villosity to the fertile stamens, as described 

 from Rich's specimen in the Torreyan herbarium); and the upper lip is so concave that, taking 

 the singular bracts and the habit into view, the plant may with reason be ranked as a genus. 



8. POGOGYNE, Benth. 



Calyx unequally and deeply 5-cleft ; the lanceolate teeth longer than the campan- 

 ulate or turbinate mostly 15-nerved tube, the two lower longer; throat naked. 

 Corolla straight, tubular-funnelform, with short lips ; the erect and entire upper lip 

 and the three lobes of the spreading lower one oval and somewhat alike. Stamens 

 4 with anthers, or the upper and shorter pair sterile, ascending, and above more or 

 less approximate in pairs : anthers 2-celled ; the cells parallel and pointless. Style 

 somewhat exserted, bearded above with hirsute hairs. Low annuals (all Californian),
