126 PROCEEDINGS OF SOCIETIES. 



Corderoy, of Diclcot, from wliom the specimen was received. — Mr. 

 K. Irwin Lynch exhibited and made some remarks on parts of the 

 Bull's Horn Acacia (A. spluErocephalu), the Imbamba tree {Cecropia 

 jjeltata), and a couple of Orchids [Epidendriim hicornutum, and 

 Schomburgkia tihicinus), as exemplifying their economy in affording 

 hollows of protection and so-called "food bodies" for ants. The 

 first two have already been described and figured by Mr. Francis 

 Darwin (Linn. Soc, Journ. Bot., vol. xv., p. 398); the last two 

 present chambers in the stems, the supposed residence of ants, as 

 in the preceding better-known instances. 



Fehnuirij, 20, 1879.— Prof. Allman, F.E.S., President, in the 

 chair. — Messrs. Edward A. Fitch, Lawrence Scott, and "Wilham 

 Stone were elected Fellows of the Society. — The Rev. G. Henslow 

 exhibited a portion of the bough of an Elm with a small pulley 

 imbedded in the centre of the wood. The rings of growth deposited 

 indicated about thirteen years of growth subsequent to the entrance 

 of the foreign body, and exteriorly all marks of its presence were 

 completely obliterated. — Mr. W. Hood Fitch next di-ew attention 

 to a colom-ed drawing of natural size of one of the remarkable 

 crimson-coloured pitchers of Xepenthes sanguinea, from Malacca. 

 This cylindrical ^Ditcher measured twelve inches long and nine inches 

 in circumference, and was grown at Bury by Mr. 0. "Wrigley. — 

 The following papers were read: — 'On the genus Oiichieya, 

 Brown,' by Dr. H. Trimen. This is a small cruciferous shrub 

 discovered by Dr. Oudney in the desert between Tripoli and Mourzuk. 

 The genus has been obscure in consequence of Brown's short and 

 insufficient diagnosis, and his reference to it of Hesperis nitens, 

 Viviani. This latter Cosson has shown to be a 2Ioricandia ; hence 

 Brown's genus has been doubtfully referred to the same. The 

 author shows from an examination of Oudney's herbarium in the 

 British Museum, that Oudneya is identical with Henojjhytoii, Coss., 

 which name it will supersede, having the j)riority of thu-ty-one 

 years. — ' On some South American genera of plants of uncertain 

 position,' by Mr. John Miers. The author refers the Fleragina 

 of AiTuda da Camara (who mentions three species) to the 

 ChrijsohalanacecB but two only should be retained in that 

 genus, the thuxl belonging to the true Couepia, Aublet. Among 

 Parinarium , the two species fully described and figured by Aublet 

 alone ought to be retained. Those to be excluded are the two 

 British Guiana sjDecies of Bentham, and seven others of Brazilian 

 origin described by Dr. Hooker, and which, from then- floral 

 structure and development of fruit, do not difter from Licania. The 

 Malayan species of Blume are shown to belong to the Petrocanja, 

 Jack., while the African species enumerated by DeCandolle, together 

 with five others yet undescribed, must be referred to Grifonia, 

 Benth. & Hook., a genus notable for the conferrumination of the 

 cotyledon of the embryo. The genus Minqiiartia , Aublet, belongs 

 to the famity Crescent iacece. Scnapea, Aublet, is also of the same 

 family and near to Kigelia. Bentham' s and DeCandolle's Kigelia 

 are widely different, the K. afrkana, Benth., properly belonging to 

 Triplnnaria. The Crescejitiacecc would thus consist of six genera.
