500 FOREST CULTURE AND 
Dolichos Lablab, LL.— Warmer parts of Africa ; 
probably thence spread widely through the tropics. 
An annual herb, sometimes lasting through several 
years. The young pods, as well as the ripe seeds, 
available for culinary use, but not of all varieties. It 
delights in rich soil, and ripens in hot countries with- 
in three months ; its yield is about fortyfold, accord- 
ing to Roxburgh. The whole plant forms excellent: 
stable-feed for cattle. 
Dracocephalum Moldavica, L.— North and Middle 
Asia. An annual, showy, scent-herb. 
Ecballion Elaterium, Richard.—Mediterranean re- 
gions and Orient. The Squirting Cucumber. An an- 
nual. The powerful purgative elaterium is prepared 
from the pulp of the fruit. Chemical principles ; ela- 
terid, elaterin, hydroelaterin. 
Ehrharta Diplax, F, v. Mueller. (Microleena aven- 
acea, J. Hooker.)—New Zealand. This tall, perenni- 
al grass is fond of woodlands, and deserves introduc- 
tion. It is likely to prove a rich pasture-grass. <A 
few other Australian species, particularly of the sec- 
tion Tetrarrhena, are readily accessible to us, and so, 
indeed, also the South African Ehrhartas, all adapted 
for our clime, the majority perennial, and several of 
superior value. Ehrharta caudata, Munro, is indig- 
enous in Japan. 
Ebriarta stipoides, Labillardiere.—Extra-tropic Aus- 
tralia; also New Zealand. <A perennial grass, which 
keeps beautifully green all through the year. For 
this reason its growth for pasturage should be encour- 
aged, particularly as it willliveon poor soil. Mr. W. 
H. Bacchus, of Bacchus-Marsh, considers it nearly as 
valuable as Kangaroo-grass, and, in the cool season, 
more so. He finds it to bear over-stocking better than
