49. Astragalus jaliscensis (Rydb.) Barneby, View in CoL Mem. New York Bot. Gard. 13: 167–168. 1964

Type:— MEXICO, Jalisco, Sierra de Tequila , 5 July 1893, C. G. Pringle 4430 (holotype: (based on Atelophragma jaliscense ): isotype: P00585283 digital image!, P00585385 digital image!, P00585384 digital image!, G00441214 digital image!

Atelophragma jaliscense Rydb., Bull. Torrey Bot. View in CoL Club 55: 157. 1928.

Perennial. Stems up to 60 cm long, suberect to decumbent, trichomes up to 0.5 mm long, straight to appressed. Stipules 3–5.5 mm long, the lowest ones clasping and connate for a half or little more, forming a bidentate sheath, the upper ones lanceolate, almost free to the base. Leaves 3–7 cm long; leaflets 19–29, 3–14 mm long, ovate, elliptic to suborbicular, obtuse to retuse, thin, adaxially glabrate, rarely with few scattered trichomes, abaxially subglabrous. Peduncles 8–16 cm long, ascendant; the racemes 5–10 cm long, flowers 12–25. Flowers ochroleucous (pale yellow); the calyx 5–5.5 × 2.8 mm, strigose, frequently with black trichomes, the tube 2.8–3.5 mm long, campanulate, the teeth 1.5–2.8 mm long, subulates; the banner 10–11.2 × 4.5–5 mm, recurved, obovate, basally cuneate; the wings 10–10.5 × 1.9 mm, the claw 4–4.5 mm long, the blade 5.9–7.5 mm long, oblong to obovate; the keel 8.5 × 2.4 mm, the claw 4–4.2 mm long, the blade 4.8 mm long, obovate. Pod deflexed, stipitate (stipe 3–4 mm long), the body oblong to oblongelliptic or clavate, dorsoventrally flattened, 2–3.9 × 0.6–0.8 cm, straight or rarely slightly curved, basally gradually narrowing in a stipe, distally contracted and ending in a small beak, ventrally rounded, dorsally flattened or openly and shallowly sulcate, the valves glabrate, ochre, papery, septum incomplete, 0.3–0.9 mm wide, pale brown or black fruit stages in the same plant; ovules 22–24; seeds 1.8 mm long, mitten shape, brown to dark brown.

Distribution:— Endemic to Mexico. Mainly distributed in Jalisco, Michoacán and Nayarit, with several northern records for Durango (Súchil) and one for Aguascalientes ( Fig. 14 View FIGURE 14 ).

Habitat:— Volcanic soils, rocky hillsides; oak forest; oak - pine forest; pine forest with Arbutus ; oak - cypress forest; 1450–2950 m.

Comments:— In the area of distribution of this species, especially in Jalisco, A. guatemalensis var. brevidentatus also occurs. Both species are morphologically very similar, and it is very difficult, if not impossible to find another character that is not the fruit to discern between these two taxa. The most obvious character of the pod is its width to length relationship, but even these measures sometimes overlap in some areas where their distributions converge.
