2. TRICHOSTEMA, Gronov. 



T. ovatum, Curran. Next T. lanceolatum, p. 348. Densely villous : leaves ovate, apiculate- 

 acuminate, subsessile, 3-5-nervose; those of the branches crowded, half-inch long: tube of 

 the villous corolla little exserted. — Bull. Calif. Acad. i. 154. — Near Baicersfield, Kern Co., 

 California, Mrs. Layne-Curran. 



T. lanatum, Benth., p. 348. Varies much in the length and hue of the wool, passing ap- 

 parently into 



Var. denudatum, with the wool remarkably short. — T. Parishii, Vasey in Bot. 

 Gazette, vi. 173. — S. California, in San Bernardino Co., and adjacent San Diego Co., G. R.

4. TEtJCRIUM, L. 



T. OCCidentale, Gray, p. 349. Extends eastward to Upper Canada (Ontario), Macoun, 

 and to near Philadelphia, Martindale. Probably passes into T. Canadense. 



14. MONARDlfiLLA, Benth. 



M. macrantha, Gray, p. 356. This varies through specimens with corolla only an inch 

 long (such as figured in Bot. Mag. t. 6270, with deep red corolla) into 



Var. nana {M- tmna, Gray, 1. c), with tube of the more slender and pale rose-colored 

 corolla little exserted from the calyx ; and 



Var. tenuiflora, with corolla full inch long and much exserted, pale rose-color, the 

 tube very slender and lobes narrow. — M. tenuiflora, Watson, in Gray, Proc. Am. Acad, 

 xvii. 230. — San Diego Co., at San Jacinto, Parish, and Lower California, Orcutt. 



M. hypoleuca, Gray, p. 356. Between Los Angeles and San Diego, Nevin, and moun- 

 tains lichiiid San Diego, Orcutt, with narrower leaves, becoming revolute and verging to 

 linear: corolla white. 



M. lanceolata, Gray, p. 357. Heads fully two-thirds inch high and ])road, or broader : 

 but on the SDUtlicrn frontier varying into 



Var. microcephala. Much branched: heads much smaller: involucral bracts 

 small, not over (juarter-inch long. — Potrero, near San Diego, Orcutt. 



M. Pringlei, Gray. Near M. lanceolata, and might pass for a variety of it : but the 

 broadly ovate and abru])tly acuminate bracts are nearly destitute of veinlets between the 



numerous nerves, and are villous, as also bractlets and calyx. — Proc. Ain. Acad. xix. 96. 



Sandy ridges, Coltou, San Bernardino Co., Pringk. Also Parry, earlier collected, probably 



in same place. 



M. thymii--6lia, Greene, Bull. Calif. Acad. i. 211, the only extra-liniital species, of the 



islands of Lower California, Veatch, Greene, is dwarf and suffruticose, with small ovate leaves.
