texture of its wood, whence it has received its popular name, ‘palo de calabaza.’ 
The deciduous leaves are alternate. The flowers, which appear in the dry 
season, before the new leaves, are of a vermilion color in all their parts, like- 
wise the branches of the terminal inflorescence. The pollen is smooth on its 
surface. The fruit resembles in shape that of the genus Cheirostemon, al- 
though much larger (20 cm, long). Tt is a 5-valved woody capsule with smooth 
interior, with grooves and numerous dents for the reception of the ascending 
seeds.” 
Marcgravia guatemalensis Standl., sp. nov. 
Branches dark brown, glabrous, minutely papillose; petioles very stout,

at the apex, chartaceous, glabrous, minutely papillose, green above, the costa

the rachis prolonged about 8 mm. above the fertile flowers; sepals 1 to 1.5 
nun. long, much broader than long, very broadly rounded at the apex; corolla

Type in the U. S. National Herbarium, no. 408015, collected near the Finc: 
Sepacuité, Alta Verapaz, Guatemala, March 28, 1902, by O. F. Cook and R. F. 
Griggs (no. 280). Additional material of the same collection, consisting of a 
sterile branch, is mounted on sheet no. 408014. 
This plant is most closely related to MW. eichleriana Wittmack, of Brazil, but 
is distinguished by the subsessile leaves and narrow nectaries. 
Tonduzia parvifolia Pittier, Contr. U, S. Nut. Herb. 12: 103, 1908, 
Heretofore this species has been known only from Costa Rica. Specimens 
collected at Cafetal Montecristo, Oaxaca, by Dr. B. P. Reko (no. 8382) seem 
to belong here rather than to 7. stenophylla (Donn, Smith) Pittier, a Guate- 
malan species. Doctor Reko gives the vernacular name as “ chamizillo.”
