LABIATE. 459 



5-dentate, pubescent : tube of the white corolla campanulate (hardly 2 lines long) and barely 

 surpassing the calyx, somewhat longer than the rounded lobes : fifth stamen sometimes an- 

 theriferous : drupes 3 lines in diameter, apparently yellow : endocarp of two 2-celled nutlets : 

 ovules amphitropous, borne at about the middle of the cell : seed pendulous from near the 

 summit of the cell, becoming orthotropous, with hollowed face, undulate-rugose on the back. 

 Li/cium brachyanthum, Gray in Hemsl. Biol. Centr.-Am. Bot. ii. 426 ; Watson, Proc. Am. 

 Acad. xi. 127. S. borders of Texas, at Laredo, on the Rio Grande, Parry, Palmer. 

 (Coahuila, Mex., Palmer, and long ago coll. by Gref/g.) C. lycioides, Don in Ediub. New 

 Phil. Jour. x. 237, coll. by Sesse & Mocino in Mexico, must be near this, and may be the 

 same. Habit very unlike the ordinary types of the genus.

2. TRICHOST^MA, 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 Bakersfield, 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. Parlshii, Vasey in Bot. 

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

 Vasey, Parish, W. G. Wright. 



4. TEtTCBIUM, L. 



T. occidentals, GRAY, p. 349. Extends eastward to Upper Canada (Ontario), Macoun, 

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



14. MONARD^LLA, 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. nana, 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 behind 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 broad, or broader: 

 but on the southern frontier varying into 



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

 small, not over quarter-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 abruptly acuminate bracts are nearly destitute of veinlets between the 

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

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

 in same place. 

 M. THYMIF6LIA, Greene, Bull. Calif. Acad. i. 211, the only extra-limital species, of the 



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