large natural order, without plates. In it Mr. Bentham first set the 

 example, in any large way, of consulting all the available herbaria for 

 the inspection and determination of type-specimens. For this he 

 made journeys to the Continent every year from 1830 to 1834, visiting 

 nearly all the public and larger private herbaria. 



In the years during which the monograph of Lahlatce was in 

 progress, Mr. Bentham elaborated and published the earlier of the 

 papers which have particularly connected his name with North Amer- 

 ican Botany. These are, first, the reports on some of the new orna- 

 mental plants raised in the Horticuliural Society's garden from seeds 

 collected in Western North America by Douglas, under the auspices 

 ot that society, by which were first made known to botanists and florists 

 so many of the characteristic genera and species of Oregon and Califor- 

 nia, now familiar in gardens, — Gilias and Nemophilas, Limuanthes, 

 Phacelias, Brodittas, Calochorti, Eschscholtzias, Collinsias, and the 

 like ; then the monograph of Hydrophijllece (1834), followed the next 

 year by that on Husackia and that on the Erlogonece^ — all American 

 and chiefly North American plants, — the first fruits of a great harvest 

 which even now has not wholly been 'gathered in, the field is so vast, 

 though the laborers have not been few. Later came the " Plantar 

 Hartwegianse," an octavo volume begun in 1839, but finished in 1857 

 with the California collections ; and in 1844, the " Botany of the Voyage 

 of the Sulphur," in quarto, the first part of which relates to Californian 

 botany. The various papers upon South American Botany are even 

 nore numerous ; one of them being that in which Heliamphora, of 

 British Guiana, a new genus of Pitcher Plants, of the Sarracenia 

 mily, was established. 



Beutham's labors upon the great order Leguminosce began early, 



vh his " Commentationes de Leguminosarum Generibus," published 



i'the Annals of the Vienna Museum, being the work of a winter's 



htday (183G-37) passed in that capital, in the herbarium then 



ditited by Endlicher. This was followed by a series of papers, 



EQ<4y monographs of genei'a, in Hooker's Journal of Botany, in the 



Joiial of the Linnean Society, and elsewhere, by the elaboration of 



theder for the imperial Flora Brasiliensis, and later, by the Revision 



of t. Genus Cassia and that of the Sub-order Mimosece^ in the Trans- 



actic of the Linnean Society, the latter (a quarto volume in size) 



publed as late as the year 1875. Both are models of monographical 



work 



Aiaportant series of monogra])hs in another and more condensed 

 form s contributed to DeCandolle's Prodromus, namely, the Tribe
