kind from Abyssinia, seemingly allied to E. stricta. The Arabian 

 and Himalayan E. flagellifera (Nees) is perennial. Other species 

 of Eleusine are deserving of trial. 



Elymus arenarius, Linne.* (Hordeum arenarium, Ascherson.) 



The " Sea-Lyme " Grass. Europe and North-Asia, on sand 

 coasts, growing in Norway to lat. 71 7'. One of the most im- 

 portant and vigorous of grasses for binding drift-sand on the sea- 

 shores. Endures being gradually covered with sand, but not so 

 completely as Psamma. The North-American E. mollis (Trinius) 

 is allied to this species. 



Elymus condensatus, Presl.* 



The Bunch-Grass of British Columbia and California, extending 

 to lat. 58. This is favorably known as adapted for sand-land. 

 Prof. Bolander says, that it does excellent service in fixing soil on 

 steep banks. Mr. W. Gorlie noted it to bear severe frost, as much 

 as F. Bunches become fully a yard in diameter and bear stalks 

 up to 10 feet high, so that in annual bulk and weight of produce it 

 surpasses all British pasture-grasses. It is also earlier than any of 

 them, and its young growth never suffers from spring-frosts ; more- 

 over it is highly nutritious and greedily eaten in all its stages by 

 stock. This grass should have some claim for adoption in scenic 

 culture. 



Elymus Virg-inicus, Linne. 



Eastern North-America. Perennial, easily spreading, but tit 

 for river-banks ; of some fodder value [C. Mohr]. 



Embothrium coccineum, L'. and G. Forster. 



From Chili to the Straits of Magellan. The Notra or Ciruelillo. 

 A tree of exquisite beauty, but seldom reaching above 30 feet in 

 height. The wood is utilized for furniture. E. lanceolatum is 

 merely a variety [Dr. Philippi]. The equally gorgeous E. 

 emarginatum of the Peruvian Andes and E. Wickhami (F. v. M.) 

 from Mount Bellenden-Ker of North- Queensland, deserve, with the 

 East- Australian allied Stenocarpus sinuatus (Endlicher), a place in 

 any sheltered gardens or parks of the warm temperate zone. 



Encephalartos Denisonii, F. v. Mueller. (Macrozamia Denisonii, Moore 

 and Mueller.) 



New South Wales and Queensland, in the littoral forest-tracts. 

 This noble Pine-palm is hardy as far south as Melbourne, and with 

 E. spiralis, E. Preissii and the South- African species to be regarded 

 as a most desirable acquisition to any garden scenery in mild zones. 

 All admit of translocation even when of large size and when many 

 years old. The lifted stems, with an unusual tenacity of life, some- 

 times remain dormant for several years. After removal they can 

 be shipped in close cases as dead goods, the leaves being previously
