THE woods of the Indian species of Juniperus, J. recurva, Ham., J. Wal- 
lichiana, Hook. f. & Thoms. (syn. J. pseudo-sabina, Fisch. & Mey.), J. macro- 
poda, Boiss. (syn. J. excelsa, Brandis, non Bieb.), and J. communis, Linn., 
are similar in general characters to those of Junipers as a whole, which are 
distinguished by the annual rings being generally narrow, often unconform- 
able and coalescent on the narrow side. The summer wood is usually thin 
but dense. The tracheids are wholly without tertiary or secondary spirals. 
Resin-passages are wholly wanting, but resin-cells are rather numerous, 
chiefly in tangential bands, often giving rise to the appearance of secondary 
growth-rings. The numerous and often resinous rays are chiefly without 
tracheids, with the ray-cells mostly with coarsely pitted terminal walls. The 
Jateral walls have half-bordered pits, round or oval, in shape arranged in 
1-2 rows radially. Fusiform rays are wholly wanting, the rays being 
mostly uniseriate, occasionally biseriate in parts, and the cells are round, 
oval, or oblong in shape tangentially. In transverse section in my specimens, 
the annual rings per inch of radius are lowest in J. Wallichiana with 26, 
and highest in J. recurva and J. communis with 44, and J. maeropoda 33.
