MvRODIA GUATEMALTECA Donn. Sm., Bor. Gaz. 16:2. 1891.— 
Hujus speciei e floribus nondum plane evolutis descriptae speci- 
mina typica cum Qzararibea Guyanensi Aubl. satis congruunt. 
Ejusdem plantae exempla Guatemalensia nuper a Barone de 
Tuerckheim transmissa et flores evolutos et fructus praebent. 
Heliocarpus Donnellsmithii Rose.— Mature leaves nearly 
orbicular, not lobed, rounded at base, shortly acuminate (tips 
mostly broken), glabrous and shining above, nearly glabrous 
below, 3 to 5-palmately veined from the base, somewhat glandu- 
lar-toothed especially at base; inflorescence a large spreading 
panicle; sepals not appendaged; stipe slender, 5"? long; body 
of fruit oblong, 5"? long, somewhat hairy, becoming glabrate 
and rugose in age. 
Near Arenal, Department Alta Verapaz, Guatemala, alt. 1500", April, 
1889, John JDonnell Smith, n. 1722 (type); Coatzacoalcos, Isthmus of 
Tehauntepec, State of Vera Cruz, Mexico, 1895, CAar/es L. Smith, n. 1002. 
This species is very different from the numerous Mexican species, and is 
near 4. Americanus Schumanni Baker, but has more glabrous leaves and an 
absence of hairs both on leaves and inflorescence. Mr. Baker's variety 
seems to me to deserve specific rank.
