and the dark brown color of the terminal spine, probable ecologic varia- 

 tions, the above collection agrees well with Johnston's description. The 

 present collection as well as his description, however, hardly bear out his 

 surmise that the plant is related to A. yaquiana Trel. The short conical 

 terminal spine, the grooved or striate perianth, and the ovoid capsule, 

 rather, express a relationship to A. datylio Simon of the Cape District of 

 the peninsula.

Ranges through the mountains south of San Ignacio to and along 

 the Sierra Giganta, its southern limits are not exactly known. Brande- 

 gee collected the type on the mesas above Comondu. Dispersed colonies 

 or stands of this Agave w^ere commonly observed by the author on the 

 rocky slopes and rocky summits of the long mesas running out westward 

 from the Sierra Giganta towards the Magdalena Plains. The rather 

 small panicles of greenish-yellow flowers are conspicuous through the 

 spring months. 



MORACEAE

Endemic to the California Gulf Region, where it occurs on many 

 of the gulf islands and the southern two-thirds of the peninsula from 

 Yubay southward. Except for Guaymas and vicinity it is lacking on the 

 mainland. Type locality is San Pedro Martir Island, where Palmer 

 first collected it. It is found principally along rocky canyons, cliffs, and 

 rocky slopes on the mountains where run-off augments the precipitation 

 in increasing soil moisture. The leaves are rather variable, but the most 

 typical form appears to be regularly cordate and during the rainy season 

 they form a dense shade.
