12 Greene Diagnoses Aragallorum. 



Aragallus Metcalfei sp. nov. 



A foot high, stout both as to the branches of the caudex and the scapes, 

 the whole plant silky-glossy with a longappressed pi lose- villous pubescence ; 

 leaflets in about 7 to 9 pairs, closely approximate, often alternate rather 

 than in pairs, oblong-lanceolate, acute, o to 1 inch long ; spikes 2 or 3 inches 

 long, dense above the middle, the lower flowers scattered ; bracts lanceolate- 

 subulate, conspicuous ; calyx cylindric, the subulate teeth hardly half as 

 long as the tube, the whole 4 lines long; corolla more than twice as long, 

 red-purple; pods about 1 inch long, sessile, very erect, nearly glabrous, 

 thinnish, the texture only firmer than that of parchment. 



In the Black Range, southern New Mexico, at 10,000 feet, O. B. Met- 

 calfe, 1904. Type in my herbarium. 



Aragallus Knowltonii sp. nov. 



Barely a foot high but stout, rigidly erect, canescently short-silky, both 

 faces of the leaflets about equally so, these in about 7 to 9 pairs, elliptic- 

 oblong, acute H inches long; scapes bearing the spikes barely above the 

 leaves ; spikes 3 to 5 inches long and rather lax, at least never dense ; bracts 

 very short and broad, ovate, acuminate; corolla red, hardly | inch long; 

 calyx not densely invested with a villous closely appressed pubescence, 

 cylindric and with short subulate teeth ; pods long and very erect, more 

 than an inch long, coriaceous, minutely and not densely silky-hairy, obcom- 

 pressed. 



In the vicinity of Flagstaff and the San Francisco Mountain, northern 

 Arizona; on Mt. Humphreys by Rusby, July 2, 1883; then by myself in 

 1889 among the woods near Flagstaff; also in the same year by Mr. F. II. 

 Knowlton, whose specimen in the U. S. Herb, is the type. 



Aragallus majusculus sp. nov. 



Branches of the caudex short, stout, the mature plant 12 or 14 inches 

 high, the short pointing spikes borne hardly beyond the very long and 

 erect leaves ; scanty pubescence of the very stout striate scapes villous, that 

 of the foliage dense, silvery -silky, of the calyx and pods more tomentulose; 

 leaflets in 5 to 7 pairs, or alternate, oblong-elliptical, about an inch long ; 

 flowering spikes thick, only lg or 2 inches long; bracts reduced and incon 

 spicuous; corollas yellowish, or perhaps pinkish ; pods hardly f inch long 

 but very thick, commonly only oblong-ovoid, sessile, erect ; fruiting calyx 

 showing subulate teeth almost as long as the short campanulate tube. 



Henry Mountains, southern Utah, July, 1894, M. E. Jones, in U. S. 

 Herb., his No. 5674 a fine fruiting specimen, being the type ; while No. 

 5695, from which caudex and flowers aredescribed, is, with hardly a doubt, 

 the same species. 



Aragallus abbreviatus sp. nov. 



Compared with A. Lamberti low, and with leaflets crowded, flowers large 

 and spike short; scapiform peduncles only 4 to 8 inches high including the
