any of the characters given prove to hold, it may bear the name 

 Neillia altirnans. I fear however that it will prove to be only 

 another of those multitudinous forms that are liable to fall into 

 N. monogyna or oputifolia. 

 ^ Neillia monogyna (Torrej^) Greene var. malvacea (Greene, 

 Pittonia, Vol. ii, p. 31 )■ I have seen the type in the University 

 of California, and recognized it at once as our common Utah form 

 with leaves a little more developed on the sterile shoots, due to 

 the more moist locality in which it was found. This is interme- 

 diate between N. opidifolia and N. monogyna, with the habit of 

 the former as well as the leaves and the pod about intermediate. 

 The calyx is not as large as in one form of N. opulifolia from 

 Colorado, the lobes are of the general shape of N. monogyna and 

 the calyx of every species and variety is campanulate, the lobes 

 of all the genus would be connivent if the pods did not exceed 

 the calyx, the calyxes of all the genus are tomentose within and 

 without but less so without, the leaves are racemose- 

 digitately (as given above) five-nerved in some of the larger 

 leaves but less so than in the var. alternans and but slightly more 

 so than in N. opidifolia. The name is not distinctive as the 

 leaves are not so malvaceous as in ^V. opulifolia var. mollis. The 

 leaves one-half to two inches long vary from reniform to ovate, 

 lobeless to deeply three-lobed with several secondary lobes, main 

 lobes above or below the middle, teeth minute and very many or 

 large and few; pubescence various and inconstant everywhere 

 except on the calyx; flowers quite large or rather small, with the 

 general appearance of A^. opulifolia as well as size; carpels gener- 

 ally two, seldom if ever inflated, united to the middle with erect 

 or spreading tips, just equaling the calyx and lobes when well 

 developed, slightly rugulose, shortly but not densely pubescent, 

 and shining beneath the pubescence; seeds three, one generally 

 larger than the others, obliquely obovate or narrower and 

 usually somewhat flattened, as is the case with the genus, 

 outline from the back often broadly lanceolate, smooth and 

 shining, yellow, not larger than in N. opulifolia and usually 

 shorter and broader than the var. mollis. The pod is dehiscent 

 on one or both sides nearly to the middle at least in many cases 

 though tardily; when not fully mature the pod is indehiscent
