Dacrydium Colensoi, Hooker. 



New Zealand. A beautiful tree, growing to 50 feet in height and 

 producing hard and incorruptible timber. Chiefly eligible for cool 

 humid forest-regions. 



Dacrydium cupressinum, Solander. 



New Zealand. Native name, Rimu; the Red Pine of the colonists. 

 This stately tree attains the height of 200 feet and furnishes a hard 

 and straight-grained wood, fairly lasting for rails, but readily de- 

 caying in waterworks and underground, but for various inside work 

 very applicable, being easily worked and comparatively cheap ; it 

 needs lengthened seasoning. Professor Kirk recommends the timber 

 on account of its great strength for .girders and heavy beams 

 anywhere under cover. With other conifers of New Zealand par- 

 ticularly eligible for forest-valleys. A most suitable tree for ceme- 

 teries, on account of its pendent branches. The bark possesses fair 

 tan-properties. 



Dacrydium Franklini, J. Hooker. 



Huon-pine of Tasmania, where it is endemic ; only found in moist 

 forest-recesses, and thus might be planted in fern tree-gullies of 

 South-Eastern Australia also. Height of tree sometimes 100 feet ; 

 stem-circumference reaching 20 feet. The wood is light, extremely 

 close-grained, highly esteemed for various artisans' work. It is the 

 best* of Australasian woods for carving, also extensively used for the 

 rougher kinds of xylography, in the manufacture of pianos and best 

 cabinet-work, also for building select boats. The tree is not of 

 celerity of growth, nor resists severe frosts. Huon Pine wood will 

 last 50 years in the ground (Abbott). 



Dacrydium Kirkii, F. v. Mueller. 



New Zealand. The " Manoao." A pyramidal tree, attaining 80 

 feet in height ; stem-diameter to 4 feet. Timber of a reddish colour 

 and extreme durability [Professor Kirk]. Bears seeds abundantly. 



Dactylis glomerata, Linne".* 



Europe, North- Africa, Northern and Middle Asia. The cocksfoot- 

 grass. One of the best of perennial, tall, vigorous pasture-grasses, 

 adapted as well for dry as moist soil, thus even available for wet 

 clays ; particularly eligible for hay. Will live under the shade of 

 trees in forests ; fit also for coast-sands. Resist drought better than 

 most of the ordinary culture-grasses. Not easily attacked by grubs. 

 Will master and choke even the Bracken-fern and other noxious 

 weeds. Mr. A. R. Crawford kept an individual plant for 20 years, 

 and it still continued to increase. Ascends the Pyrenees to 9,000 

 feet [Boissier], and is indigenous in Norway to lat. 68 50' [Schue- 

 beler]. Its yield of foliage is rich and continuous, but its stems are
