1 62 PATAGONIAN EXPEDITIONS I BOTANY. 



Add Macl., p. 528, at foot of page the variety: 



LATHYRUS MAGELLANICUS Lam. var. CAMPESTRIS Dus. nov. var. 



Plate III. 



Humilis, glaucescens, glaberrimus ; folia patentia, foliolis breviusculis, 

 lanceolatis, vel late-lanceolatis, mucronulatis, epetiolatis, membranaceis, 

 stipulis semi-sagittatis ; pedunculi elongati, 3-4-flori, floribus cyaneis, 

 glabris, quam in typo submajoribus. 



Caulis ad 5 cm. usque longus; petiolus c. 5 mm. longus; foliola 15-18 

 mm. longa et c. 5 mm. lata ; pedunculi 6-7 cm. longi ; flores fere 2 cm. longi. 



S. Patagonia, on subhumid meadows near Rio Sta. Cruz, about 40 km. 

 from its mouth. 



This variety differs from the type in low growth, smaller leaves, greater 

 flowers and comparatively long peduncles. It does not grow blackish in 

 drying. It stands near to L. magellanicus Lam. var. oxyphyllus Speg., dif- 

 fering from that variety in much smaller and semisagittal stipules, shorter 

 and patent leaflets and larger flowers.

L. MARITIMUS Big. 



Occurs also on the Guaitecas Islands and on the opposite coast of the 

 continent. 



L. NERVOSUS Lam. 



Not rare in the southern and middle section of the steppe, especially 

 near the forest district, sometimes abundant. This species is known by 

 me from the districts of Lago Argentine, Lago Viedma, Lago San Martin 

 and Lago Buenos Aires. D. 



L. PRATENSIS L. 



Should be struck out ; the determination refers to V.patagonica Hook. fil. 



P. 530 : 



L. PUBESCENS Hook, et Arn. 



According to Spegazzini this species is not rare through all Patagonia. 

 There is, probably, some exaggeration in this statement. In the year 

 1905 I crossed S. Patagonia from the mouth of Rio Sta. Cruz to Lago 

 Argentino and continued the explorations northwards to Lago San 

 Martin without seeing a single specimen of this species. D.
