solitary trees, the cones are collected in groups of four, five, or even a larger 

 number, and will remain on the trees closed for several years. In British 

 gardens, the tree is of as rapid growth as P. Tae'da or P. pungens.

There is a tree bearing this name in the Hackney arboretum, which, in 

 184-0, was upwards of 13 ft. high, with 3 leaves in a sheath, and pendulous 

 branches reaching to the ground. The leaves and young shoots have every 

 appearance of those of P. rigida ; and, though the tree has not yet borne cones, 

 we have little doubt of its belonging to that species. The plant was received 

 from the Liverpool Botanic Garden in 1820.

Sjtec. Char., Sfc. Leaves in threes, very long. Male catkins 

 erect, incumbent. Cones ovate ; scales having very small 

 mucros. Buds, on young trees (see^^g. 1824.), from 

 ^in. to ^in. in length, and from y\in. to Jin. 

 in breadth ; conical, dark brown, and very resinous ; 

 buds on old trees as in fig, 1825. Leaves (see fig. 

 1827.), in the Dropmore specimens, from 4 in. to 

 6 in. long; in Michaux's figure, upwards of 8 in. long. 

 Cones 2i or 3 inches long, and 1^ or 2 inches broad ; 

 egg-shaped ; scales |. in. long, and f in. broad, with 

 the apex depressed, and terminating in a slender 

 prickle. Seed very small ; with the wing, from ^ in. 

 to |- in. in length. Cotyledons, ?. The cones and 

 leaves of the trees of this name at Dropmore, and 

 the circumstance of there being trees at Pain's Hill with 

 cones of different sizes and shapes, but all on three-leaved 

 pines, and all evidently of the Tge'da family, induce us to 

 believe that P. rigida and P. serotina are only different 

 forms of the same species. A middle-sized tree. New 



Jersey to Carolina, on the edges of ponds, and 

 in swamps. Height 30 ft. to 40 ft. Introduced 

 in 1713. It flowers in May, and the cones are 

 ripened in the autumn of the second year, but 

 do not shed their seeds till the third or fourth 

 year, whence the specific name. 



The tree has a branchy trunk, from 15 in. to 

 18 in. in diameter, and in America it rarely 

 exceeds from 35 ft. to 40 ft. in height. The 

 timber consists chiefly of sap wood, and is 

 of very little use except for fuel. The leaves 

 are generally 5 or 6 inches long, and some- 

 times more. The male catkins are straight, 

 and about ^ in. long. The cones are commonly 

 in pairs, and opposite to each other ; they are 

 about 2i in. long, nearly 2 in. in diameter, and 

 egg-shaped ; the scales are rounded at their ex- 

 tremities, and armed with fine short prickles, 

 which are easily broken off, so that in some cases 

 no vestiges are left of their existence. This, 

 like the other kinds of P. Tas^da, forms an inte- 

 resting addition to the pinetum, growing freely 

 at Syon, Pain's Hill, and Dropmore
