276 SCBOPHULAEINE*. 



corolla dark red-purple; tube! in. long, widening into ashort-funnelform 

 throat and bilabiate limb; lubes of the lower lip only half as long as the 

 upper, and more spreading: capsule 4 — 5 lines long, narrow, obtuse, 

 subterete, unequal-sided: seeds few, large, obovate, minutely granular. 

 Var. parviflorus. All parts of the plant thrice smaller; the corolla 

 sparcely % i n - l° n g 5 its tube little exserted. — The type quite common on 

 hillsides near the coast; the variety in the Vaca Mountains. April, May. 



5. E. Bolanderi (Gray), Greene. Glandular-pubescent and viscid, 

 14 — 2 ft. high, simple or branched: leaves ovate and oblong 1 — 2 in. 

 long: calyx-teeth unequal, acuminate: corolla red-purple, % — 1 i n - ^ on S, 

 the tube rather abruptly widening to the not very irregular spreading limb: 

 capsule fusiform-subulate, as long as the calyx. — Mt. Hamilton, Mt. 

 Diablo, etc. June — Aug. 



9. MIMULUS, Linn. Herbaceous light green and flaccid plants, 

 glabrous or slightly pubescent, some albuminous-viscid, others musk- 

 scented, none resinous-glandular. Flowers peduncled, axillary and 

 solitary, or becoming racemose by reduction of the upper leaves to 

 bracts. Calyx 1 5-angled, commonly short and bilabiate, the uppermost 

 lobe largest. Corolla in most of ours yellow, often personate, seldom 

 otherwise than strongly bilabiate. Stamens 4; stigma bilamellar. Cap- 

 sule obtuse, enclosed within the calyx; the membranaceous walls 

 (apparently not valvate) tardily separating from the central and con- 

 joined placentae. 



1. M. cardinalis, Dougl. Stout, viscid-pubescent, rather strong- 

 scented when bruised, 2 — 4 ft. high: leaves ovate and ovate-lanceolate, 

 erose-dentate, parallel-veined, sessile, 2 in. long: corolla scarlet, 2 in. 

 long, very irregular ; 3-lobed lower lip reflexed; upper less deeply divided, 

 the undivided part erect, the lobes reflexed: stamens exserted. — Mount- 

 ain streams, and on wet rocky hillsides. June— Sept. 



2. M. moschatus, Dougl. Perennial, slender, soft-villous, slimy, 

 musk-scented: stems 1 ft. long, decumbent, rooting at the joints: leaves 

 oblong-ovate, 1 in. long, petiolate; corolla light yellow, % in. long. 

 Var. sessilifolius, Gray. Leaves 2 in. long, sessile by a broad base: 

 corolla 1 in. long, the ample spreading limb nearly regular: herbage 

 only faintly or not at all musk-scented. — Swampy places in the Coast 

 Range; probably the variety only, with us. May — Sept. 



3. M. floribundus, Dougl. Annual, diffuse, slender, villous, very 

 slimy, 6-10 in. high, leafy and flowering from the axils throughout: 

 leaves ovate, 1 in. long or less, the upper shorter than the pedicels: 

 calyx short-campanulate, ovate or oblong in fruit, and with nearly equal 

 short triangular teelh: corolla % — % *"• l° na i only twice the length of the 

 calyx, light yellow: capsule globose-ovate, obtuse. — Common in the 

 mountains far north and south; not known in those about the Bay, but 

 found in Lake Co., and to be expected in Sonoma and Marin.
