204 GAMOPETALOUS EXOGENS 



295. COLM^S V 1IA, L. 



[In honor of Pder CoUinsmi, of London; an eminent promoter of Natural Science.] 

 Calyx declined in fruit, ovoid-campanulate, about 10-nerved, bila- 

 biate; upper lip flattisk, truncate, 3-toothed; lower lip bifid; throat 

 somewhat hairy. Corolla elongated, dilated at throat, sub-bilabi- 

 ate ; upper Up nearly equally 4-lobed ; lower lip longer, declined, 

 dentate, or lacerately fringed. Stamens usually 2, much exserted, 

 diverging, the upper pair being shorter and imperfect, or wholly 

 abortive. Nutlets often solitary by abortion, and then globular and 

 rather large. Perennials: leaves large; flowers solitary, in panicu- 

 late racemes. 



1. C. CaiaadeilSis, L. Leaves ovate, acuminate, coarsely ser- 

 rate, petiolate, thin and smoothish; racemes elongated, many-flow- 

 ered ; flowers pedicellate, axillary and opposite. 

 CANADIAN COLLINSONIA. Knot-root. Horse-Balm. 



Stem 2 to 3 feet high, somewhat branched, smoothinh below, pubescent above. 

 Leaves 4 or 5 to 8 or 10 inches long, and 3 to 5 inches wide, resinous-dotted beneath ; 

 petioles 1 to 3 or 4 inches long, the leaves at the base of the panicle smaller, and 

 sub-sessile. Flowers loosely racemose; pedicels % to % an inch long, with 

 minute lance-ovate acuminate brads at base; cm-olla greenish yellow, the lower 

 lip fringed. 

 Halt. Rich woodlands: frequent. Fl. July. Fr. Sept. 



Obs. The root of this was formerly a popular febrifuge. The 

 odor of the flowers has much resemblance to that of Hops, a fact 

 which was noticed by JOHN BARTRAM, in his Appendix to SHORT'S 

 Medicina Britannica, a century since. This interesting plant, which 

 commemorates one of the most diligent correspondents of LINNAEUS, 

 and the early, indefatigable, and devoted friend of JOHN BARTRAM, 

 is thus fancifully referred to, in Dr. DARWIN'S Poem, the Botanic 

 Garden: 



" Two brother swains, of COLLIN'S gentle name, 

 The same their features, and their forms the same, 

 With rival love for fair COLLINIA sigh, 

 Knit the dark brow, and roll the unsteady eye. 

 With sweet concern the pitying beauty mourns, 

 And soothes with smiles the jealous pair by turns." 



TRIBE 3. MONA^RDEAE. 



Corolla mostly bilabiate ; stamens 2 (the upper pair usually wanting, or mere 

 rudiments ;) anther-cells widely separated by a long connective, or divaricate, with 

 an inconspicuous one. 



296. SAI/VIA, L. 



[Latin, salvare, to save ; on account of supposed medicinal properties.] 

 Calyx subcampanulate, bilabiate; upper lip mostly 3-toothed, the 

 lower bifid ; throat naked. Corolla ringent ; upper lip erect, straight, 

 or falcate. Anther- cells separated by a long linear thread-like con- 

 nective, which is transversely articulated with the filament. Cymules 

 in interrupted racemes. 



1. S. OFFICINALIS, L. Suffruticose ; hoary-tomentose ; leaves lance- 

 oblong, crenulate, rugose ; upper lip of the corolla as long as the
