Pinus Torreyana, Parry. 



California. A small coastal Pine, buffeted by the sea-breeze 

 [Prof. Sereno Watson]. Leaves very stout. An average cone of 

 this pine will contain about 130 seeds, weighing 3 ounces ; they are 

 edible [Meehan]. 



Finus Tsuga, Antoin -. 



Northern provinces of Japan, 3,000 to 9,000 feet above the sea. 

 This very hardy spruce-fir grows to a height of over 100 feet. Its 

 timber is durable, tough and dense, used for masts and spars, also 

 for shingles, which will last 30 to 40 years [Matzunoj ; highly- 

 esteemed for superior furniture, especially by turners. It is of a 

 yellowish-brown colour. P. Araragi (Siebold) is the oldest name 

 for this species, as pointed out by Prof. C. Koch. 



Pinus Webbiana, Wallich. 



King-Fir, Dye-Fir, Himalaya-mountains, at an elevation of 

 from 7,000 to 13,000 feet, extending to Afghanistan. A splendid 

 fir, reaching a height of 150 feet, the stem a circumference of 30 

 feet. Will bear a good deal of shade [Dr. Brandis]. The wood is 

 pale, soft, cross-grained and very resinous, on the testimony of Mr. 

 Webb somewhat similar in texture and odour to that of the 

 Bermuda-Cedar.' The natives extract a splendid violet dye from 

 the cones. The oldest name for this species is P. spectabilis (D, 

 Don) according to Prof. C. Koch. 



Pinus Williamson!!, Newberry. 



California and Oregon, up to 12,000 feet. Height of tree reaching 

 150 feet. Timber very valuable [Vasey]. Many other pines, 

 eastern as well as western, not alluded to on this occasion, are 

 worthy of especial utilitarian inquiries. Pines are the leading trees 

 for imparting that permanent green into landscapes, derivable 

 almost solely from Conifers in cold climes, and all the more 

 appreciated by refined taste for mass- planting with wider scope 

 in zones of evergreen vegetation, where most kinds of trees with 

 deciduous foliage, however eligible for street-planting, are out of 

 their element, and look only for about two months lovely, for two 

 passable, for two unsightly and without winterly surroundings for 

 six months dead, and that during the very time of the most beautiful 

 general verdure. 



Piptadenia Cebil, Grisebach. (Acacia Cebil, G-risebach.) 



La Plata- States. A tree, attaining 60 feet in height, there 

 furnishing a tan-bark of fair strength [Hieronymus]. 



Piptadenia rigida, Bentham. 



Sub-tropical and extra-tropical South-America. This acacia-like 

 tree furnishes the angico-gum, similar to gum arabic. The wood r 

 according to Saldana da Grama, serves for naval constructions.
