NOTICES OF BOOKS. 



work, which bears the title of * Plantas Hartwegianas imprimis Mexica- 

 nas adjectis nonnullis Grahamianis enumerat novasque describit Georgius 

 Bentham' It is now complete, occupying nearly 400 closely printed 

 pages, including the very perfect Index. Although the Title-page bears 

 the date of 1839, it was not concluded till 1856. , 2230 species are 

 enumerated ; these are the results of the researches of Mr. Theodor 

 Hartweg, Collector for the Horticultural Society of London, who com- 

 menced his journeyings in 1836. His dried specimens were on sale, 

 sent home at different periods with numbers attached to them, and 

 all these, to the great advantage of the public, Mr. Bentham undertook 

 to name and distribute for the benefit of the collector. 



1. The first set sent home, No. 1-258, were collected in the country 

 north of the City of Mexico in 1837. 



2. No. 259-443, apparently from the same region, collected in 1838. 



3. No. 443-552, are from the territory of Oaxaca, and towards 

 Vera Cruz. 



4. No. 523-631, from Guatemala. 



5. No. 632-707, from Columbia, near Guayaquil. 



6. No. 708-869, from Loxa, Columbia. 



7. No. 870-1531, from the Magdalena and the Andes of Quito, Po- 

 payan, and Bogota. All those from Columbia were collected between 

 1841 and 1843. 



8. No. 1544-1589, from Jamaica. (The plants of Columbia and 

 Jamaica are followed by a systematic enumeration of the both.) 



9. No. 1590-1624. These form part of the Mexican collections 

 which were gathered iu 1836, and accidentally omitted. 



10. The last, and not the least interesting portion of this fine Haifa 

 wegian set, including No. 1625-2042, were collected in California 

 during the years 1846-7, chiefly about Monterey and Sacramento,' 

 and we scarcely know which to admire most, the ardent zeal of Mr. 

 Hartweg in forming such extensive collections in such varied regions, 

 or the botanical skill of Mr. Bentham in thus enumerating and describ- 

 ing them. 



It will be seen that the numbering of the specimens (2042), do not 

 correspond with the « species enumerated" (2230), which is accounted for 

 by the fact that, in the Collection, species are, from different localities, 

 occasionally numbered more than once ; and on the other hand, a great 

 many species are added (without numbers) from species which were too 

 tew for distribution.
