leaves oblanceolate, contracted into a broad margined petiole, 

 usually finely denticulate but sometimes coarsely dentate, obtuse, 

 lower stem leaves oblong- lanceolate and denticulate at apex, 

 auricled, upper stem leaves lanceolate and the uppermost ovate^ 

 acute, broadly auricled, reduced; racemes one to two feet long, 

 close, wand-like; pedicels five to eight lines long, ascending, rarely 

 horizontal in fruit, slender in flower; sepals narrow, two to three 

 lines long, obtuse; petals white or tinged with purple, four to 

 five lines long, oblanceolate to oblong-obovate; anthers curved 

 and always partly or wholly exserted; flowers usually one-half 

 as long as pedicels; pods one-half a line wide, three inches long, 

 generally spreading at an angle of 45°, occasionally bent in an 

 arc downwards, but no specimens with pods all arched, pedicels 

 never reflexed; stipe a mere rudiment; beak one to three lines 

 long. This is a close congener to T. ambiguum, but pods stipe- 

 less, beaked, lower stems always pubescent, flowers much 

 smaller and nearly white, and pedicels longer. A form from 

 Green River Utah, that I refer to this species is simple stemmed 

 and with appressed pods. 



Westwater, Colorado, May 7, iSgi, also adjoining Utah. 

 Common on the adobe plains of the desert. 



Caidanthus crassicaulist Watson var. glaber, n. var. glabrous 

 throughout. Otherwise exactly as in the species. Type from 

 Summit near Sink Valley, S. Utah at 7000 feet altitude June 23, 

 1890. During the present year I have seen this occasionally in 

 eastern Nevada along with the species. It is quite striking but 

 passes into the type. 



Lepidhim monianuin, Nutt. var. alyssoides (Gray Pi. Fend. 

 10). It is so manifest that this is only a more enduring form of 

 L. viontamim that it is useless to keep it up as a species longer. 

 It passes by insensible gradations into the type. 



Lepidiuin Utahense^ Jones in Herb. This is the plant which 

 Watson wrongly referred to L. montanum as a form of his var. 

 heterophylluni. It was first published by me in my lists of the. 

 Flora of Utah collected in 1880 and published early in 1881 but 

 without a description. In the thirteen years which have elapsed 

 since, I have never seen anything to change my original opinion,
