The description given 



the P. mitis of Michaux ; being without the 

 violet-coloured glaucous bloom on the joung 

 shoots ; having rigid leaves, generally in threes ; 

 and a cone with very strong prickles, like that of 

 P. Tae'da, to which species we have referred if. 

 The only plants that we know which answer to 

 Michaux's description of P. mitis are at Drop- 

 more, where they are readily known by the violet- 

 coloured glaucous bloom on the young shoots, 

 and by the leaves being almost all in twos ; at 

 the same time, it is proper to mention that the 

 leaves there, though soft and slender, are much 

 shorter than those in Michaux's figure. Tiie 

 name applied to this species at Dropmore is P. 

 variabilis. There is also a plant at Dropmore 

 named P. mitis ; but it is wholly with three 

 leaves ; and, as far as we can ascertain (the 

 tree not having yet borne cones), it belongs 

 either to P. serotina, or to some variety of it. 



by Miller of P. echinata, as having finely elongated leaves, and a cone with 

 very slight slender prickles, agrees perfectl}' well with this species, as described 

 by Michaux ; and not at all with Mr. Lambert's P. variabilis, which he de- 

 scribes as having leaves only 2 in. long, and cones with scales having " thorny 

 points of a strong woody texture projecting from them." 



i \6. P. conto'rta Douglas. The tviisie&-branclied Pine. 



Buds roundish, with a blunt point, covered with resin, and brown. Leaves 

 2 in a sheath, 2 in. long ; sheath very short, imbricated, black. Cones from 

 2 in. to 2h in. long ; and from | in. to 1 in. broad ; scales with the apices having 

 Xv>-.^ " n;,!/^ a depressed lateral rib, termi- 



nating in a blunt point, fur- 

 nished with a caducous mucro. 

 The shoots are regularly and 

 closely covered with leaves, 

 much in the same manner as 

 those of P. (s ) pumilio, to 

 which the specimen sent home 

 by Douglas, in the Horticul- 

 tural Society's herbarium, 

 bears a general resemblance. 

 This pine was found by 

 Douglas in North-west Ame- 

 rica, on swampy ground near 

 the sea coast ; and, abun- 

 dantly, near Cape Disap- 

 pointment and Cape Lookout. 

 Fig. 1814. to our usual scale, and Jig. 1815. of the natural size, are from 

 the specimens in the Horticultural Society's herbarium. 



1 17. P. TURBiNATA Bosc. The Top-shaped-co^ierf Pine. 



Leaves 2 in a sheath, slightly glaucous, scarcely 1 in. long. The buds 

 are very small, reddish, fringed, and not resinous. The cones are in whorls 

 from 2 to 3 together, sharply pointed, longer than the leaves, with the scales 

 almost square, and not pyramidal. Bosc thinks that it is probably a native 

 of North America ; but his description is taken from a tree in the garden of 

 the Petit Trianon, about 40 ft. high, the only one he had seen. He adds that 

 its general appearance resembles that of P. mitis ; but it differs in its leaves 

 being much shorter, and its cones being without spines.
