10 SEEDS AND PLANTS IMPORTED. 



and the like. In soups and catsups it gives body to the dish ; stewed it is muci- 

 laginous, and while at first not agreeable to many persons a taste for it is 

 easily acquired. It is also dried and canned for winter use. When ripe the 

 black or brown white-eyed globular seeds are sometimes roasted and used as a 

 coffee substitute." (Bailey, Standard Cyclopedia of Horticulture, vol. 4, p.

41725. Persea Americana Mill. Lauraceae. Avocado. 

 (Per sea gratissima Gaertn. f.) 



From Altadena, Cal. Purchased from Mr. F. O. Popenoe, West India Gar- 

 dens. Received January 12, 1916. 



Seeds of a hardy type of avocado, pui'chased for fumigation experiments. 



41726. Abbtjtus arizonica (A. Gray) Sarg. Ericaceae. 



Madrona. 



From the Santa Rita Mountains, Arizona. Collected by Dr. David Griffiths, 

 of the Bureau of Plant Industry. Received January 12, 1916. 



"This is a tree commonly a meter in circumference and 10 meters high, but 

 often much larger. The old trunks have a bright, light-gray bark and the 

 branches are light osier red. The contrast with the permanent light-green 

 leaves and coral-red berries is very striking. To my mind this is one of the 

 most ornamental of native southwestern trees and should be propagated and 

 widely distributed. Indeed, the whole group of inanzanita-arctostaphylos 

 arbutus trees and shrubs are very ornamental broad-leaved evergreens, and 

 our native ones are all but unknown in the trade. It is going to take some 

 careful experimentation to make them ready for handling, but they will prob- 

 ably be found to be no more difficult than the rhododendrons. AVe need to 

 know how best to propagate them. Some of the manzanitas are easily trans- 

 planted, and probably the closely related plants may also be handled in the 

 same way, but trees small enough are not numerous in parts where I have 

 traveled. They are said to grow from hardwood cuttings with difficulty. The 

 trees are usually found under typical forest conditions where the floor is cov- 

 ered with a great deal of debris. They probably require an acid soil. This 

 particular lot of seed conies from an altitude of 6,000 to 7,000 feet in the Santa 

 Rita Mountains, Ariz., where snows are frequent and I judge temperatures 

 must often touch the zero mark. I suggest, since the quantity of seed is small, 

 that the germination be tried under greenhouse conditions. This is trans- 

 mitted for propagation at Chico, Cal." (Griffiths.)
