ohovata, which, according to Dr. Oudney, grows wild in 

 small quantities in Wady Ghrurbi. 



PapilionacejE. Twenty-six species of this tribe are 

 contained in the herbarium, none of which form new genera, 

 and the only two species that appear to be unpublished 

 belong to Indigofera. 



Alhagi Maurormn, or Agoiil, is abundant in Fezzan, 

 where it forms excellent food for camels. 



CompositjE. Of this class, thirty-six species exist in the 

 collection. The far greater part of these were found in the 

 vicinity of Tripoli and in the Desert. All of them appear 

 to belong to established genera, and very few species are 

 undescribed. 



RubiacEtE. The herbarium contains only six species of 

 this family, five of which, belonging to Spermacoce and [ssg 

 Hedyotis, were found in Bornou and Soudan ; the sixth, a 

 species of Galium, near Tripoli. 



Of Asclepiade^ only three plants occur. One of these 

 is a new species of Oxystelma, exactly resembling in its 

 flowers O. escalentum of India, from which it differs in the 

 form of its leaves, and in that of its fruit.-' A species of 

 Dcemia was found in the Desert ; but the specimens are 

 too imperfect to be ascertained. 



Of Ajpocinea, strictly so-called, there is no plant whatever 

 in the collection ; and of Gentianese, a single species only of 

 Erythrsea. 



SESAMEiE. An imperfect specimen of Sesamum pterO' 

 spermum, of the catalogue of Mr. Salt's Abyssinian plants,^ 

 is in the collection from Bornou. 



SapotEjE. The only plant of this family in the herbarium 

 is the Micadania, or Butter Tree of Soudan, particularly 

 noticed by Captain Clapperton. The specimen, however, 

 is very imperfect, consisting of detached leaves, an incom- 

 plete fruit, and a single ripe seed. On comparing these 

 leaves with the specimen of Park's Shea Tree,^ in the
