NORTHWESTERN PLANTS. 119 



appressed-ciliate: corolla blue, 1.6 to 1.8 cm. long: mature nutlets 

 whitish, about 3.5 ram. long, their surfaces somewhat corrugated. 

 Collected by Wlllidvi C. Cusiek on dry mountains near Sparta, 

 Union County, Oregon, 25 May, and 3 June, 1898, no. 1886, also 

 in the same locality, no. 856 (coll. of 1880). " Commonly growing 

 in the shade of small shrubs," hence the specific name. M. umbra- 

 tilis is closely related, as shown by the foliar characters, to M. 

 sibirica, Don, but differs conspicuously from it in the longer lanceo- 

 late acute calyx-lobes, the larger corolla, and in the somewhat 

 larger fruit, 



Lophanthus Cusickii. Low much-branched suffrutescent her- 

 baceous perennial, 1.5 to 3 dm. high, covered throughout with a 

 short close evenly spreading pubescence: leaves ovate or triangular- 

 ovate, 1 to 2 cm. long, about two-thirds as broad, unequally 

 crenate-serrate, obtuse or acutish, narrowed below into a petiole; 

 petioles equaling or shorter than the blade: the congested terminal 

 spikes often nodding at least in the earlier stages: calyx-teeth 

 narrowly lanceolate, attenuate, purplish. Collected by William C. 

 Cusiek on dry mountain-sides of Stein's Mountains, southeastern 

 Oregon, 4 July, 1898, no. 2001. This species is most nearly 

 related to L. urticifolius, Benth., from which, however, it is dis- 

 tinguished by its lower moi*e branching habit, smaller usually 

 cuneate leaves, more evident pubescence, and by the longer and 

 more attenuate calyx-teeth. 



Mimulus (Eunanus) clivicola. Low herbaceous annual, 

 2 to 15. cm. high, glandular pubescent throughout: stems sim- 

 ple or branched from the base: leaves oblong-ovate to oblanceo- 

 late, 0.5 to 2 cm. long, a third to one-half as broad, 3-nerved, 

 entire or more commonly somewhat toothed toward the obtuse 

 apex, more or less glandular-pubescent upon either surface: flowers 

 axillary: pedicels 0.5 to 1.5 cm. in length: calyx 6 to 10 mm. long, 

 about equally 5-toothed; teeth ovate, acute, 2 mm. long: corolla 

 pale-purple or yellowish, often spotted at the throat, narrowly 

 funnel-form, 1.2 to 2 cm. in length, evidently bilabiate, pubescent 

 in the throat, the lobes bearing a few scattered hairs on their upper 

 or inner surface: capsule linear-oblong, somewhat attenuate and 

 curved above, slightly overtopping the persistent calyx. Idaho,
