hmgiflora is sent as a fibre producer. Several new species of Indigo- 

 fera were found in the parcel ; as well as a new species of Garcinia, 

 from which the natives take a red dye ; and Khaya senegalends {V) 

 Jus., out of whose long straight trunk the natives fashion canoes ; 

 the Gonioma, peculiar to tropical Africa, yielding a white juice, 

 allied to India rubber ; likewise Enjthrojjldceum guineeiise, Don, used 

 here, as throughout Africa, for the purposes of the ordeal ; and two 

 new Ferns. 



Professor Dickson commended the judgment and care shown by 

 Mr Buchanan in sending this new parcel of specimens. Altogether 

 he had been a most satisfactory botanical correspondent. 



V. Microscopic Demonstration of Embryonic Specimens of 

 Salvinia natans. By Mr E. Kidston. 



A series of preparations of the prothallium of Salvinia natans 

 were exhibited under the microscope. The stomata of this plant 

 have been described by Schleiden as consisting of small slits without 

 guard cells. On the upper surface of the scuteUum, however, the 

 stomata are of considerable size — about five times as large as those 

 of the floating leaves, and distinctly provided with guard cells. 

 There seems little doubt but that guard ceUs are also present on the 

 leaf "slit like" stomata; but they are very small, and require very 

 careful focussing to see them.
