BOTANY. — The Middle American species of Lonchocarpus. Henry 

 Pittier. Contributions from the National Herbarium 20, part 2. 

 Pp. 37-93, pis. 1-6, figs. 1-43. 1917. 

 Lonchocarpus belongs to the family Fabaceae (Bean Family), sub- 

 family Dalbergieae. The species are trees or shrubs, and are chiefly 

 American, a few being found in Africa and Australia. In the present 

 paper all the Central American species represented in American her- 

 baria are described, as well as several from the West Indies, Colombia, 

 and Venezuela. The Central American species are arranged in 6 

 groups, Philenopteri, Spongopteri, Punctati, Epunctati, Concavi, and 

 Carinati. Forty species are recognized, twenty-two of which are new. 

 Two species published in the genus Derris are transferred to Loncho- 

 carpus. Notes upon the habit and ecology of the species are included, 

 as well as a list of the vernacular names asigned to some of them.

BOTANY. — Preliminary revision of the genus Ingci. Henry Pittier. 



Contributions from the U. S. National Herbarium 18, part 5. Pp. 



173-223, pis. 81-105. 1916. 

 The genus Inga is a member of the Mimosaceae or Mimosa Family 

 and is confined to tropical America. It was monographed by Ben- 

 tham in 1875, but the large accumulation of recent material has neces- 

 sitated a revision of the species. The genus is divided into five sec- 

 tions, Leptinga, with 26 species, Diadema, with 19 species, Bourgonia, 

 with 14 species, Pseudinga, with 117 species, grouped in 8 series, and 

 Euinga, with 36 species, in 2 series. Forty-one species and one sub- 

 species are described as new. P. C. S.
