y E 
Plante Wrightiane e Cuba Orientali (Polypetale et Apetale), a 
A. GRISEBACH. 
(Read August 14, 1860.) 
[Tn collection of dried plants of which Professor Grisebach has here commenced to give the determi- 
nations, with diagnoses of the new genera and species, was made by Mr. Charles Wright, in the eastern part 
of the island of Cuba, partly in the years 1856 and 1857, and partly in 1859 and the beginning of 1860. 
The specimens were mainly gathered in the high country and mountains behind Santiago de Cuba and Cobre 
(mostly within a moderate distance of Filanthropia, the hospitable country residence of George Bradford, 
Esq.), and especially in the elevated district back of Santa Catalina de Guantanamo, where the collector’s 
principal station was Monte Verde, a coffee-plantation and residence of the most estimable and hospitable M. 
Lescaille ; from which place as a centre Mr. Wright is still prosecuting and extending his herborizations. That 
the field is a rich and promising one, the great number of interesting and new species, enumerated in this and 
the following papers, abundantly show. In the distribution of these materials, the fullest set of the collection of 
1856-57 was assigned to Professor Grisebach, in order that they might be studied by him, along with the 
materials of his Flora of the British West Indian Islands, now in course of publication. This set, enriched by 
the collector’s valuable memoranda, was unfortunately lost on its way to Göttingen. As it could be only par- 
tially replaced, certain species of the first distribution have not been examined by Dr. Grisebach. Such of 
these species as I could name, more or less confidently, I have ventured to intercalate, always enclosing such 
additions, and other brief annotations I have had occasion to make, within brackets. When extracts from 
Mr. Wright’s memoranda are given, they are placed within quotation-marks. Determinations of the Mono- 
petale, &c. will follow.— Asa Gray.]
