Franseria arborescens. Arborescent, 3-5 m. high, canescent- 
ly pubescent; leaves coriaceous, 15 cm. long, 5-8 cm. wide, on 
petioles 2-3 cm. long, ovate in outline, serrate, long acuminate, 
deeply cut into 2-3 coarsely serrate lobes, pubescent beneath, 
greener and puberulent or hispid above; heads naked paniculate; 
fertile involucres pubescent, armed with 7-8 stout subulate spines 
hooked at the tip, 2-3 flowered. 
Not uncommon from Santa Gertrudis to Cabo San Lucas, The 
Santa Gertrudis specimens are more hispid and smaller than 
those from the south. This plant has been distributed by me as 
F. flexuosa, but by the kindness of Dr. J. M. Greenmann incom- 
paring it with the type, I am enabled to distinguish and de- 
scribe it. ; 
Sabazia Purpusi. Annual, stems 2-3 dm. high, simple or 
sometimes branched near the base, sparingly hirsute-pubescent; 
leaves ovate, acuminate, 1-2 cm. long, serrate, on petioles 2 mm. 
long or less; inflorescence terminating the stems; peduncles 2-4 
cm. long, rarely branched, bearing one or two small bracts; rays

Common on rocks along the coast between Cabo San Lucas and 
San José del Cabo, where the glaucous plants are conspicuous on 
account of their color. It differs from P. gracile in having larger 
salicornia-like leaves, in its intricately branched habit, white ap-
