﻿48 SEEDS AND PLANTS IMPORTED. 



41567. Wasabta pungens Matsumura. Brassicacese. Wasabi. 

 (Eutrema wasabi Maxim.) 



Roots from New York, N. Y. Presented by Mr. H. Terao. Received De- 

 cember 6, 1915. 

 " Before cooking, the graded wasabi is usually beaten so that the root cells 

 may be mostly broken up, as you have perhaps learned in Japan. It is said 

 that there is no wasabi for sale in New York City yet. Two Japanese restau- 

 rants here get 50 roots a year from San Francisco, where the wasabi comes 

 from Japan." (Terao.) 



41568. Diospyros ebenaster Ketz. Diospyracere. Black sapote. 



Seeds from Honolulu, Hawaii. Presented by Mr. Gerrit P. Wilder. Re- 

 ceived December 4, 1916. 

 A tall "tree with fragrant white flowers and very sweet fruits, the size of an 

 orange, green outside and almost black within. Native of Mexico. See S. P. I. 

 Nos. 39719 and 40338 for previous introductions and full description. 



41569. Fraxintjs excelsior L. Oleacese. Ash. 



From Dublin, Ireland. Presented by Dr. A. Henry, Royal College of 

 Science. Received December 1, 1915. 

 Var. monopliylla. One-leaved ash. In this remarkable variety of the com- 

 mon European ash the terminal leaflet only, or occasionally one or two more, 

 is developed. In other respects it is the same as the common ash. Its one 

 leaf is oval or ovate, long stalked, toothed, and variable in size, usually 3 to 6 

 inches long, li to 2| inches wide, but often proportionately broader or shorter. 

 I have measured it as much as 8 inches long and 5 inches wide. This variety 

 has arisen independently in many places, both cultivated and wild, and varied 

 considerably. It is also known as integrifolia, heterophylla, and simplicifolia. 

 The species itself is one of the most valuable of all our timber trees, yielding 

 a whitish wood of great toughness and durability. Elwes considers it at the 

 present time the most economically valuable of British timber trees. For 

 some purposes, especially in coach building and implement making, it has no 

 rival, either native or foreign. An isolated ash of goodly size makes a tree of 

 great beauty and dignity, forming a shapely oval or rounded head of branches. 

 It likes a deep moist, loamy soil, and thrives well on calcareous formations. 

 In some parts of the north of England, on the east side of the Plain of York, 

 for instance, it is a common hedgerow tree, almost as common as the elm is in 

 the south. In such positions, especially where the adjoining fields are arable, 

 it is not an unmixed advantage, being one of the grossest of feeders. (Adapted 

 from W. J. Bean, Trees and Shrubs Hardy in the British Isles, vol. 1, p. 567.)
