mm. long; stipules linear, 2 mm. long; flowers not seen; fruit apparently borne in 

 small panicles; carpels elliptical, oblong, 3.2 to 4.5 cm. long, less than 2.5 cm, wide, 

 rounded at botli ends. 



Collected by J. N. Rose near Colomas, State of Sinaloa, in the foothills of the 

 Sierra Madre, July 16, 1897 (No. 1706). 



This is the most northern species known, all the species referred to by Homsley in 

 the Hiologia being confined to south Mexico and Central America, 6 of the 15 being 

 from Panama. The other species are apparently all from the Tropics, while this 

 species is found in the edge of the Lower Sonoran area at an altitude of about 2,900 

 feet. This is a very important vine and much used by the people on the west coast 

 of Mexico, where it is known as "bejuco Colorado." It is used in many ways, and

takes the place of ropes, wires, etc., among the plain people. It is employed in 

 making the cactus fences to fasten the upright trunks together. In the building of 

 their rude huts it serves to tie fast the rafters. I saw, at Palmacito, Sinaloa, a vine 

 18 meters long used for a clothes line. The vine is said to have great strength. A 

 second species grows along the coast, but I was repeatedly told that the " bejuoo 

 Colorado" was always obtained from the mountains.
