^ I ^HE following notes relating to Ceylon plants have been 

 --^ compiled for the information of Ceylon botanists from 

 the papers cited. In some cases it has been possible to add 

 a few further details. 



(1) Blatter, E., and Hallberg, F. A Revision of the Indian 

 Speeies of Rotala and Ammania. Jour. Bombay Nat. 

 Hist. Soc, XXV., pp. 701-722. 



Under Rotala verticillaris L. (p. 705), Ammania Rotala Clke. 

 non Muell., the authors refer to a Ceylon specimen of this 

 species in Herb. S. Kurz. [Ammania' Rotala, in Flora of Ceylon, 

 III., 224:.— EdJ 



(2) Dunn, S. T. Notes on the Flora of Madras. Kew 

 Bulletin, 1916, pp. 58-65. 



The notes on Gyclea Burmanni sl'ould receive attention from 

 Ceylon botanists. 



Gardamine subumbellata Hook, is said to be identical with 

 the earlier Gardamine trichocarpa Hochst. Gapparis stylosa 

 DC. is adopted for G. divaricata W. & A. [See Flora of Ceylon, 

 I., p. 61 : the Ceylon plant is insufficiently known. — Ed.] 

 Gapparis zeylanica Linn . is considered identical with Gapparis 

 horrida Linn. f. ; the author's interpretation of the specimens 

 in Herb. Hermann differs from that of Trimen. According 

 to Dunn's conclusions, the Gapparis zeylanica of the Flora of 

 Ceylon will be G. brevispina DC, as in Thwaites Enum, 15, 

 but he does not cite Ceylon specimens. Bergia capensis L. is 

 restored for B. verticillata Willd. Abutilon hirtum G. Don has 

 precedence of A. graveolens W. & A., and A. glaucum Cav. of 

 A. muticum G. Don.
