Rácz, István; Huyen, D. D.: Study of a low-elevation occurrence of Pinus dalatensis Ferré (Pinaceae) in Gia Lai province, Vietnam

140 RÁCZ, I. and HUYEN, D. D. less initially pruinose, later greenish or reddish-grey, becoming grey in subsequent years. (As shown by BUSINSKY (1999), the first-year shoots are sparsely, unevenly or densely pubescent in P. d. var. dalatensis, totally glabrous in var. bidoupensis, and mostly densely pubescent in subsp. procera). Needles in the Kon Jot area are 4.5-10.5 cm, light green abaxially, silvery-white adaxially. Cones are 6-14.5 cm, with stalks up to 2.5 cm, conical to conical-cylindrical, with convex scales; mature open cones are in various shades of yellowish- or reddish-brown, weathering to brownish-grey or light grey; umbos are blunt. Seeds are 4-6 mm, long-winged (2-3 cm). Cone variation is illustrated in Figure 5. Fig. 5. Cone variation based on specimens collected from under six mature trees of P. dalatensis (a-e: #69224x, f: #69176).
