Pinus io 45 



who informs me that the largest specimen raised from this introduction is growing at 

 Harcourt (Eure), and is now about 8 ft. high, and producing' annual shoots about a 

 foot in length. There are smaller trees at Les Barres and Verrieres. There are also 

 specimens of the same origin at the Arnold Arboretum, and some of these sent by 

 Professor Sargent in 1902 to Kew are only about 2$ ft. in height. A tree from the 

 same source planted at Colesborne. in 1905 has gradually pined away, possibly on 

 account of the limy soil. 



The finest specimens of this species in cultivation are seven trees at Kew, which 

 were raised from seed sent by me from Mengtse in Yunnan in 1897. They are 10 

 to 15 ft. high ; and three of them bore fully developed cones in 1909. Wilson 1 sent 

 seeds from Hupeh to the Coombe Wood Nursery in 1900, and the seedlings raised 

 are about 2\ ft. high and very flourishing. P. Armandi promises to be a valuable 

 ornamental tree. (A. H.)

A shrub, usually prostrate, and rarely if ever exceeding 10 ft. in height. Buds 

 resinous, about \ in. long, cylindric-conic, ending in a sharp-pointed apex ; scales 

 reddish brown, closely appressed. Branchlets covered with a dense brown 

 tomentum. Leaves closely crowded on the branchlets and directed forwards, 

 parallel with them, in fives, those in each cluster appressed together, incurved, 

 \\ to 2, rarely 3 in. long, white with stomatic lines on the two inner surfaces, 

 entire or faintly serrulate 2 in margin ; resin-canals marginal ; basal sheath entirely 

 deciduous. 



Cones never opening, sub-sessile, about ij in. long and 1 in. in diameter, ovoid, 

 often curved, reddish or orange brown when ripe ; scales few, about ^ in. broad, 

 concave interiorly with a partition between the cavities for the seeds, upper edge 

 sharp and bevelled ; umbo terminal, darker in colour than the rest of the apophysis, 

 ending in a minute, thickened, triangular, reflexed tip. Seed about \ in. long, 

 pear-shaped, convex on the lower, and flattened on the upper surface, brownish, 

 wingless, edible. 



1 Cf. Hortus Veitchii, 343 (1 906). Seeds of this species, erroneously ascribed to/ 1 , koraiensis, were sent by Wilson 

 in 1899 f rora Yuanchiang in Yunnan, but do not appear to have germinated. Kent, in Veitch's Man. Conifera, 335 (1900), 

 also erroneously considers the Yunnan tree to be P. koraiensis. 



2 Specimens from Japan show both entire and serrulate leaves. Those from other regions have apparently always entire 

 leaves. The cones are identical.
