 paria, elliptica-subobovata, obtusissima saepe paulo emarginata, margine ± revo- 

 luto, 8—12 X 5 — 6 mm, obscure viridia, subtus pallidiora, supra glabra, subtus 

 inferne et secus medianum pilis albis longis patentibus dense vestita, ceterum

latum, locellis 8 — 10 mm diam., obscure fuscum, albopilosum, omnino exalatum,

Masafuera: Guajardo! Johow! — Q. de las Casas, on shelves along the 

 walls of the gorge (fr. % 17, no. 504); Q. de las Vacas (Johow); Q. Angosta; 

 Q. del Varadero. 



This differs from all other forms in the pubescence of the leaflets, illust- 

 rated above; part of the hairs are longer and more crisp than in S. fernandeziana, 

 as Fig. 13 shows. There is also considerable difference in the flower and, still 

 more so, in the pod. Besides the characters given the smooth surface of the 

 pod and the thinness of its walls are to be remembered. The wings, of which 

 there is a vestige in the former, are quite wanting or, at most, represented 

 by an irregular row of tubercles. The variation in the colour of the seed should 

 be noted. 



Johow says that he found a form of Sophora in Masafuera differing from 

 Philippi's species, but his material certainly belongs to the latter. 



Area of distribution: Endemic in Masafuera.
