REPORT ON CUBAN EXPLORATION. 
Dr. N. L. Brirron, Drrector-INn-CHIEF. 
Sir: In accordance with your instructions, I sailed from New 
York City December 3, 1910, and spent three weeks in the 
provinces of Havana and Pinar del Rio in making a collection of 
botanical specimens for the Garden. 
Upon my arrival at Havana on the morning of December 7, 
I was met by Brother Leén, ofthe Colegio de la Salle at Vedado, 
who had made arrangements to accompany me during my three 
days’ stay in that province. 
December 8 was given to exploration in the coastal region 
between Morro Castle and Cojimar. Here, however, owing to 
a severe drought and an unfavorable season, few plants were 
in flower or fruit. 
Of the shrubs, one of the most common is a species of Zanthoxy- 
lum (Z. taediosum), a relative of the “‘Hercules-club” of the 
Bahamas, and originally described from specimens collected in 
the vicinity of Cabafia. In sandy places back from the coast, 
this species often attains a height of five or six feet, but growing 
as it sometimes does on exposed littoral rocks it becomes dwarfed 
and prostrate. 
everal species of Lantana were frequently met with, occa- 
sionally growing together, and conspicuous on account of their 
brilliant red, orange, or white flowers. 
The spurge family was represented in the coastal sands by 
several small, prostrate species of Che maesyce, and in the thickets
