var. veitchii Shaw

P. veitchii Roezl, nom .
P. bonapartea Roezl ex Gard. Chron.
P. loudoniana Gord

Body of seed relatively larger, about {1/2} in. long, wing shorter and relatively broader, about {1/2} in. long. Cones sometimes as long as 15 in., with scales 1{1/8} to 1{1/4} in. wide. According to Martinez there is the further difference that the scales are thicker and stronger than in the typical state of the species. This variety is apparently confined to central Mexico, where intermediate forms also occur (Martinez).P. ayacahuite and the var. veitchii are both likely to vary in hardiness, according to provenance. The famous tree at Westonbirt is now decrepit and no longer bears cones, but at one time it coned freely and many seedlings were raised from it (some of which proved to be hybrid; see P. × holfordiana). This tree certainly belongs to the var. veitchii; Shaw, who saw cones from it in the Herbarium of the Arnold Arboretum, actually cites it in his description of var. veitchii. The statement by Elwes and Henry that var. veitchii is tender probably refers to the original introduction by Roezl (as P. veitchii).Among the largest or oldest specimens of P. ayacahuite (some may be var. veitchii) are: Kew, pl. 1873, 54 × 3{1/2} ft (1974) and another, possibly a seedling of the Westonbirt tree, pl. 1904, 49 × 4{1/2} ft (1966); R.H.S. Pinetum, Wisley, Surrey, 62 × 7{1/4} ft (1969); Hergest Croft, Heref., pl. 1916, 60 × 6 ft (1968); Bicton, Devon, 88 × 7{1/2} ft and 78 × 8{3/4} ft (1968); Bodnant, Denb., pl. 1902, 64 × 10{3/4} ft and 71 × 10{1/2} ft (1974); Fota, Co. Cork, Eire, pl. 1902, 60 × 7{3/4} ft (1966).The Westonbirt specimen of var. veitchii, mentioned above, has lost its top; it measured 62 × 6{3/4} ft in 1909 and is now 8{1/2} ft in girth (1971).
