sides reflexed to the sulcus, a line deep and mostly below, the 

 edges nearly touch behind, pink-purple, deeply notched, white 

 spot narrowly oblong, 5 lines long, filling all of the sulcus, in- 

 terruptedly purple-veined, goes almost to the tip where it shades 

 into purple, sulcus U-shaped below but it soon disappears into 

 a mere groove above 2j4 lines below the tip; petals thin; wings 

 2^2 lines long, oblong, oblique, notched on the lower side near the 

 tip, fully a line wide, obtuse tip a trifle larger, scarcely arched,, 

 purple above, concave to keel and tips overlapping beyond keel, 

 not flaring, 1% lines longer than keel; keel 1 J4 lines long and 

 high, abruptly rounded to 90 degrees, with tip obtusely-triangu- 

 lar; banner 5 lines longer than keel; pods strongly and sharply 

 conical-subulate beaked, round, smooth, fleshy, sides equally 

 thickened *'-£. line thick, outer part a transparent pulp, inner more 

 fibrous, but it cuts very easily and is not woody, full of pulp, 

 notstipitate (when dry the pulp shrinks away and leaves a dis- 

 tinct pseudostipe ^ to 1 line long) dorsal suture intruded y 3 to- 

 to ^ the way; leaves not fleshy, sharp, but they are very hard 

 to dry; flowers tipped with pink-purple, horizontal to a trifle re- 

 flexed; pods ascending on a horizontal very stout pedicel, in the 

 green pod eaeh cell is almost cylindrical. This differs from A. 

 nudus Watson in the 2 celled pod, broad and large leaflets, in- 

 much the same manner as A. reventus differs from A^ conjunctus. 

 A. Shockleyi Jones is very near to A. nudus but can still be 

 kept apart from it by the shape and character of the pod, though 

 it is probable that they will intergrade as more material comes 

 to light. 



Astragalus crassicarpus var. pachycarpus (A. ^pachycar- 

 pus T. & G. Fl. i 332). This seems to be a good variety. It is 

 Texan, though it is found in Arkansas and even in Missouri. 

 Stems slender with many nodes, rather short subulate stipules; 

 the most developed leaflets are in 11 to 16 pairs, narrowly- 

 elliptical-oblanceolate, rather long-petiolulate, less than 6 lines 

 long; peduncles 1 to 3 inches long, usually 2 inches long, few- 

 flowered; calyx cylindric; pedicels slender; bracts long-subulate; 

 2 lines long; flowers slender, white or whitish, 8 to 9 lines long; 

 plants nearly glabrous, calyx hairs either absent or rather sparse
