Stems scarcely angled at base, 3-winged upwards. Stipules leaf-like, 

 entire ; leaflets 2, linear-lanceolate, entire, pale underneath. Corolla yel- 

 lowish and glabrous, scarcely equalling the calyx-teeth. Pod erect, gla-

N. Patagon., escaped. 



3- L. EPETIOLARIS CloS. 



Perennial, smooth, blackish in drying. Stems 1-2 meters high, tetrag- 

 onal, scarcely winged. Leaves short-petioled ; leaflets linear-lanceolate, 

 5-7 cm. long. Tendrils long, trifid. Stipules triangular, semisagittate, 

 3-4 times as long as the petiole. Inflorescence 10-15 cm - l n g. 4-8- 

 flowered at its end. Calyx-teeth linear-acute, exceeding the tube, and the 

 lowest the longest. Corolla purple-violet. Legume linear, compressed, 

 as large as a leaflet, smooth. Seeds numerous. 



(Chili) ; Chubut, by Carren-leofu. " The Patagonian forms have the 

 stipules sagittate, not semisagittate." (Speg.) 



4. L. MACROPUS Gillies. 



Robust plant, laxly pubescent, stem angulate and striate. Lower leaves 

 with i, the upper successively with 2-4 pairs of lanceolate leaflets, ending 

 in a stiff point. Stipules semisagittate, linear-lanceolate, in the upper 

 leaves shorter than the petioles. Tendrils of upper leaves long and 

 parted. Inflorescence 3-4 times as long as the leaves. Flowers numer- 

 ous, the rachis and calyx pubescent. Calyx-teeth acuminate, one of them 

 subulate. Corolla large, blue (?). Legume unknown. 



(Chili) ; Chubut, by Carren-leofu (stipules of these sagittate, not semi- 

 sagittate). 



5. L. MAGELLANICUS Lam. 



Glabrous, blackish, suberect. Stipules broad-ovate-oblong, ending in 2 

 divaricate lobes. Cirrhi trifid. Leaflets i pair, 25-50 mm. long, elliptic-
