 through numerous and very various forms. The following are dwarf or depauperate 

 varieties. 



Var. alpinus, Gray. A span or less bigli, equably leafy to the top : loaves lialf 

 an inch to an inch long, ovate or oval, denticulate or some of them entire : stems 1-4- 

 flowered: corolla proportionally largo (an inch or loss long). — Proc. Acad. Philad. 

 1863, 71; Watson, Bot. King Exp. 224. M. Tilingii, Pogel, Oartenll. 18G9, t. 

 631, — the same plants the second year developing into the ordinary condition of 

 the species, and figured by Regcl, 1. c. 1870, 290, t. GG5. M. cupreus, Veitch, in 

 Gard. Chron. 1864, 2; Regel, 1. c. 1864, t. 422 {M. luteus, var. cuprea, Hook. f. 

 Bot. Mag. t. 5478), — a form with the corolla turning orange or copper-red. 



Var. depauperatus, Gray. Slender, mostly smooth, and Avith sharply-toothed 

 or laciniato leaves (from a fourth to half an inch long), slender i)otiolos, and filiform 

 peduncles twice or thrice the length of the small flowers : corolla only a third or 

 half an inch long: Bomo forms much approaching M. alsinoides ; but the calyx is 

 that of M. luteus, except in size. — M. inicrophyllus, Bonth. in DC. 1. c. M. tend- 

 lus, Nutt. herb., not of Bunge. 



Moist or wet grounds, very common, cxtendins; north to the Alaskan Islands, east to the 

 Rocky Mountains, and sotitii along the Andes to the extremity of Chih. The var. alpinus in 

 the Sierra Nevada, &c. The var. dcjm.uperattis consists of reduced forms, flowering as tiny or 

 slender annuals, in Oregon and California. 



M. DKNTATUS, Nutt., fron\ the woods of Oregon, if a variety of this species is a peculiar one, 

 glowing in much shade. Tlio jdaiit so named in tlic l^otniiy of 'Wliiiiples Expedition (Pacif. R. 

 Rep. iv" 64) is a smaller-flowered and depauperate form of M. hitcvs. 



M. AUSiNOinEs, Dough, of Oregon and British Columbia, resemhles the last variety of M. Ivtcns, 

 but is known by the narrower calyx, in fruit oblong (3 or 4 lines long), and tlie teeth very short ; 

 also by the filiform at length divaricate peduncles, of an inch or more in length, and nearly all of 

 them longer than the ovate or roundish leaves, tlieso nil i)etio]ed. The Inrgest forms are a foot 

 high, and dillusely much branched, with narrow corolla half an inch lung. The smallest (var. 

 mtniimis, Benth.) are minute, with corolla only 2 lines long. 



15. M. laciniatUS, Gray. Annual, glabrous, small and very slender, a si^n or 

 loss in height, dilfusn : caulino loaves oblong or si>atulate, mostly laciniately few- 

 toothed or lobed, sometimes hastate, 1-nervod, a (piarter to half an inch long and 

 with filiform petiole of equal or greater length : petl uncles about the length of the
