270 GEAN: ALMOND, ETC. 



1 3 cm., with 2 reddish glands above. Flowers with the 

 leaves, which are conduplicate in bud. A variety or sub- 

 species of P. Cerasus. Autumn leaves passing through 

 fine orange-reds or rich yellows to pink and crimson reds 

 and browns. 



Venation pinnate-reticulate, with little tendency to 

 looping. The midrib gives off about 10 secondaries on each 

 side, pinnate at open angles, but soon breaking up beneath 

 the margins, the forking more conspicuous than the 

 looping, and the ends of the tertiaries and smaller veins 

 passing into the teeth. Reticulation abundant. Each 

 pair of secondaries distant about T V ^ the length of the 

 midrib. The outer tertiaries leave the secondaries at 

 acute, the inner at obtuse angles, and tend to form nearly 

 transverse cross-ties. 



[Forms of P. Cerasus with the petiolar glands developed 

 may be looked for here, but the leaves are glabrous, or 

 nearly so, and not soft and pendent.] 



8 8 Leaves glabrous or nearly so, and 

 not pendent. Shoots glabrous.

 ceolate, conduplicate.
