454 SCROPHULARIACEAE (FIGWORT FAMILY) 



panulate, in flower about 8 mm. long, often mottled with dark purple, at 

 length much inflated, the 4 lower teeth incurved and closing the orifice: 

 corolla yellow, 2-3 cm. long, funnelform; lobes of the upper lip erect, oblong, 

 the middle lobe of the lower lip broadly cordate, pendulous; the throat usually 

 spotted with dark red, the pubescent lines running to the base: capsule ob- 

 long; seeds oblong. (M. puberulus Greene.) In wet places in the mountains; 

 New Mexico to Montana and far westward. 



5. Mimulus Geyeri Torr. Nicol. Rep. Hydrog. Upper Mississippi 157 

 1843. Perennial by stolons, glabrous or nearly so; stems slender, creeping, 

 rooting at the nodes, 1.5-5 dm. long: leaves broadly ovate, orbicular, or broader, 

 very obtuse, denticulate or entire, membranous, truncate, subcordate, or 

 rarely narrowed at the base, palmately veined, short-petioled or the upper 

 sessile, 6-25 mm. broad: peduncles slender, longer than the calyx in fruit: 

 calyx oblique, scarcely toothed, 6-8 mm. long at maturity: corolla 8-12 

 mm. long, the lower lip bearded at the base within, the throat broad: seeds 

 nearly smooth. M. Jamesii. From Mexico to Montana. 



6. Mimulus moschatus Dougl. in Lindl. Bot. Reg. 13: pi. 1118. 1827. 

 Villous and slimy-viscid, strongly musk-scented; stems creeping and ascend- 

 ing, 1.5-3 dm. long: leaves ovate or oblong, short-petioled, denticulate, 

 rounded or subcordate at the base, 2-5 cm. long: peduncles slender, longer 

 than the calyx; flowers 2-5 cm. long: calyx-teeth lanceolate, acuminate: 

 corolla 2-3 times as long as the calyx. The MUSK PLANT of gardens and green- 

 houses; also indigenous in wet places from Colorado and Wyoming to the 

 Pacific States. 



7. Mimulus Hallii Greene, Bull. Cal. Acad. Sci. 1: 113. 1886. Puberulent 

 or glabrous, more or less branched, usually suberect, rather slender, the stems 

 somewhat angled: leaves and bracts oblong or ovate, obtuse, entire or spar- 

 ingly dentate: calyx subglobose-inflated, with rather broad abruptly acute 

 teeth, the upper one twice as large as the others: corolla light yellow, small, 

 6-10 mm. long, the slender tube scarcely exserted. (M. thermalis A. Nels. 

 Bull. Torr. Bot. Club 27: 269. 1900; M. nasutus Greene, as to our range.) 

 Wet, springy places; eastern slope of the Rocky Mountains. 



8. Mimulus floribundus Dougl. 1. c. pi. 1125. Villous annual with spread- 

 ing white hairs and viscid; stem rather slender, 5-40 cm. long, at first erect, 

 but soon decumbent and diffusely spreading, flowering from the lowest axils: 

 leaves ovate, or the lower subcordate, the blade 12-25 mm. long, rather 

 coarsely toothed, all petioled: peduncles spreading, 1-3 cm. long, exceeding 

 the leaves: calyx campanulate, about 6 mm. long, the short, triangular, acute 

 teeth nearly equal: corolla about 12 mm. long, light yellow, funnelform: cap- 

 sule globose-ovoid, obtuse, sessile: seeds almost globular, light-colored. (M. 

 membranacea A. Nels. Bot. Gaz. 34: 30. 1902.) From the mountains of 

 Colorado and Wyoming to the Pacific States. 



13. RHINANTHUS L. YELLOW RATTLE 



Herbs, with erect stem, opposite leaves, and mostly yellow subsessile flowers 

 in the axils, the upper ones crowded and secund in a leafy-bracted spike. 

 Calyx ventricose-compressed, 4-toothed, inflated in fruit. Corolla-tube cy- 

 lindraceous; the upper lip galeate, ovate, obtuse-compressed, entire at apex 

 but with a minute tooth on each side; lower lip shorter, with 3 spreading 

 lobes. Capsule orbicular, compressed. The seeds when ripe rattle in the in- 

 flated dry calyx. 



1. Rhinanthus Crista-galli L. Sp. PI. 603. 1753. Glabrous or nearly so, 

 2-4 dm. high: leaves narrowly oblong to lanceolate, coarsely serrate: bracts 

 incised and the acuminate teeth setaceous-tipped: corolla 10-12 mm. long, 

 only the tip exserted, commonly with a purple spot on one or both of the 

 lips: stamens ascending under the galea; anthers pilose, the cells transverse: 

 seeds suborbicular, winged. From the Rocky Mountains eastward to the 

 Atlantic.
