IN EXTRA-TROPICAL COUNTEIES. 95 



Dactylis csespitosa, Forster. (Poa Forsteri, Steudel.) 



Fuegia, Falkland's Island, South Patagonia. The Tussock 

 Grass. Introduced by Sir Joseph Hooker into the Hebrides, 

 and by Mr. Traill into the Orkney Islands. Delights, accord- 

 ing to Mr. Ingram, in deep, boggy, and mossy land, even when 

 exposed to sea-spray. Cultivated plants might be dressed 

 with some salt. Thrives in cold countries near the sea in pure 

 sand, at the edge of peat bogs. It would likely prosper in our 

 Alpine moors. It is perennial, and reaches to a height of 9 

 feet. It is very nutritious, and much sought by herds. The 

 base of stem is nutty and edible. 



Dactylis glomerata, Linne.* 



Europe, North Africa, North and Middle Asia. The Cocks- 

 foot Grass. Perennial. One of the best of tall pasture grasses, 

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

 wet clays. It will live also under the shade of trees in forests. 

 Its yield of fodder is rich and continuous, but its stems are 

 hard. It is already largely cultivated, and has become natur- 

 alised. It is generally liked by cattle, unless when by under- 

 stocking or neglect it has been allowed to become rank. Lan- 

 gethal observes : " What the Timothy Grass is for the more 

 dry sandy soil, that is the Cock's-foot Grass for more binding 

 soil, and no other (European) grass can be compared to it for 

 copiousness of yield, particularly if the soil contains a fair 

 quantity of lime. It grows quickly again after the first cut- 

 ting and comes early on in the season. The nutritive power 

 of this grass is of the first class." 



Dactylis litoralis, WUldenow. {Poa litoralis, Gouan.) 



From the Mediterranean countries to Siberia. This stoloni- 

 ferous grass can be utilised for binding coast-sands ; but it is 

 of greater importance still in sustaining a Kermes insect (Por- 

 phyrophora Hamelii), which produces a beautiful purple dye 

 (Simmonds). 



Dalbergia miscolobium, Bentham. 



Southern Brazil. This tree supplies a portion of the Jacaranda 

 wood (Tschudi). 



Dalbergia nigra, AUemao. 



Brazil, down to the Southern Provinces. A tall tree, likely to 

 prove hardy in our warmer and lower regions. It yields a 

 portion of the Jacaranda or Palisander Wood, also ■ Caviuna 

 Wood, which, for rich furniture, have come into European use.
