          long and 2 inches wide. The native East Indians eat the young snow-
white leaves, which are tender and sweet, and also the unopened flower
heads. The screw pines are among the finest decorative plants, and

51700. PARTHENIUM ARGENTATUM. Guayule. From Marfa, Texas.
Plants presented by R. A. Epperson. A small, spreading shrub, native
to a restricted area in southwestern Texas and northern Mexico, where
it is exploited commercially for the rubber which is obtained from it.
The plant has been utilized extensively for its rubber, and is worthy

the region mentioned above. The shrub rarely attains to a height
greater than 3 feet; it has small, silvery gray leaves and bears yellow 
composite flowers.

climber from the Ecuadorian Andes, where it is cultivated in gardens
for its edible fruits, which are oblong, about 3 inches in length,
orange-yellow in color, containing orange pulp of acid, aromatic flavor, 
very agreeable when strained and mixed with milk and sugar to

ornamental, with abundant foliage of attractive appearance, and large,
pink flowers. The slender oblong fruits, suggesting cucumbers in appearance,  contain orange-colored, subacid pulp similar in flavor to
that of the other tacsos of northern South America.

for cultivation in California and Florida, and which is highly
ornamental in character, and valued for covering arbors and pergolas.
The oval fruit, about the size of a hen's egg, has a thick, brittle
