FIGWORT FAMILY. ISTD 



12. M. latidens Greene. Animal, glabrous, slender, erect and simple, or 

 commonly with several ascending- branches from the base, the internodes below 

 the inflorescence very long; leaves sessile, ovate to ovate-lanceolate, remotely 

 denticulate or entire, !/_> to 1 in. long; pedicels surpassing, often much surpass 

 ing the leaves, or the uppermost leaves reduced to bracts and the inflorescence 

 subracemose; flowering calyx cylindric, 3 lines long or less; fruiting calyx 

 ovate-campanulate ; corolla nearly white or slightly yellowish, little exserted, 

 the narrow limb almost regular; capsule oblong. — (M. inconspicuus Gray var. 

 latidens Gray.) 



Low wet fields: Sacramento Valley; Napa Valley; Antioch. Apr. -May. 

 Basal leaves often subrosulate and petiolate. Herbage sometimes slightly 

 viscid-puberulent. 



13. M. langsdorffii Donn var. guttatus Jepson. Annual, or perhaps 

 sometimes perennial by the production of stolon-like stems at base; stems 

 simple or sometimes branching, one to several from the base, about 1 to 2 

 ft. high; herbage glabrous or slightly pubescent; leaves more or less elliptical, 

 thinnish, irregularly serrate or dentate, the lower petioled, the upper sessile; 

 petioles mostly shorter than the blades; flowers in a terminal raceme; pedicels 

 shorter than or equaling the flower; calyx in anthesis 3 to 5 lines long, in 

 fruit often nodding, somewhat longer and nearly or quite twice as broad; 

 calyx-teeth often disposed to be approximate or connivent in age, the upper 

 the longer; corolla yellow, with purple or brown dots in throat, % to 1 in. 

 long. — (M. guttatus DC. M. luteus of Bot. Cal., etc.) 



Sierra Nevada and high North Coast Ranges. June-Aug. A highly variable 

 but exceedingly interesting species which in the Bay region has developed an 

 attractive array of varieties, some of which are here described as follows: Var. 

 ENSIGNIS Greene; annual (as all the following), 6 to 20 in. high; foliage very 

 scanty; lowest petioles long; corollas 1 to 1% in. long, with a large purple 

 splotch and several small purple dots on the lower lip. — Napa and Sonoma 

 valleys. Apr. One of the most showy plants of the genus. Var. arvensis 

 Jepson; size of the preceding or larger; lower leaves often with several pairs 

 of small leaflets near the main blade; floral leaves sometimes soft-villous; orifice 

 of the mature calyx broad-campanulate, commonly truncate. — Wet fields: How- 

 ell Mountain and elsewhere. Var. califorxicus Jepson; annual, simple or 

 branching, stoutish, y 3 to 2 ft. high; leaves round or roundish, often broader 

 than long (as in all the following varieties, especially the sessile upper ones), 

 dentate or sharply serrate, often with narrow salient lobes at base; flowers 1 

 to 1% in. long. — Common in the Sacramento and Coast Range valleys. Apr.- 

 May. Var. graxdis Greene; similar to the preceding but said to be perennial; 

 stems fistulous, 2 to 3 ft. high; leaves ample (as much as 3% in. long), on 

 short petioles; flowers l 1 /^ to 2 in. long. — Rank form found along ditches and 

 slow streamlets in the Bay region. May-Sept. Var. xasutus Jepson; stems 

 !/4 to 1^2 ft. high; teeth of the calyx in mature fruit often very strongly 

 turned towards the upper one which is thrice the length of the others; corolla 

 large or little surpassing the calyx. — Mountain rivulets and springs of the 

 North Coast Ranges and doubtless elsewhere. Apr. -May. 



14. M. floribundus Dougl. Annual; stems slender, at first erect, later 

 diffuse, 5 to 15 in. long; herbage more or less slimy-viscid and musk-scented ; 

 leaves ovate, % to 1 in. long, dentate, short-petioled; pedicels mainly longer, 

 sometimes shorter than the leaves; calyx narrowly campanulate (in fruit ovate),
