scaly; " twigs gray-brown, dull, glabrous, with numerous 
small but very evident pale lenticels ; " buds ovate acute, 
about one-fourth inch long, with pubescent scales, the 
outer acuminate, often with subulate points; " fruit about 
an inch long, depressed; husk 6 mm. thick, splitting to 
below the middle; nut broader than high, mucronate at 
both ends, the apex truncate or depressed ; shell nearly white

known only from Palmer, 835^, from the high mountains 
of Alvarez, twenty miles southeast of San Luis Potosi, at 
an altitude of 8,000 ft. — The only species not native to the 
United States.— PL 19, f. 1-3. 
In its husk characters and pubescence, this is most 
closely related to //. alha, but the bark (if really shaggy), 
bud, leaf and nut characters, bring it close to H. ovata. 
= = Fruit subglobose or ellipsoidal; hnsk very thick, completely sepa- 
rating into 4 pieces; nut rather thin shelled, the kernel large and 
sweet. — In this group many of the petioles remain adherent to the 
twigs during the winter.
