common in Northern Michigan and Wisconsin, it does not seem to 
extend farther westward than the Saskatchawan, where it is replaced by 
P. contorta 
42. P. australis, Michx. Male flowers 24-3 inches long, the longest of 
any pine, of rose-purple color; lowest pair of involucral bracts minute. 
On a very vigorous shoot I have seen the female ament lateral (see p. 170), 
arare anomaly. In the germinating plantlet, the long wing remaining 
attached to the seed shell is raised up like a flag by the growing cotyled-

Cubenszs, Griseb. Leaves in threes, only exceptionally in twos, 
8-10 a re es long, rarely longer, stout, about § line wide, rigid, strength- 
ening cells largely developed under the epidermis (so that their bundles 
sometimes extend from the epidermis to the ducts) and also near the ves-

e flowers about aie hes long; involucral bracts 13-15, the outer pair 
aa as long as the inner ones; anther-crests scarcely denticulate; cones 
24-3 inches long, bet elias scales depressed; seeds 3$ lines long, 
faintly ridged; wing nearly twice as long, widest at base, oe to an 
acutish point. The var. tertrocarpfa, Wright, in Gris. Cat. Cub. 217, is a 
very curious form but not a variety. It seems that in this case the growth

different parts of Cuba, in the maritime districts as well as on the moun- 
tains, and is probably the same that gives the name to the Isle of Pines.
