18 BURMA, ITS PEOPLE AND PRODUCTIOXS. 



A few words are needed here by way of apology for the confused aiTangcment 

 of this group of phmts. I collected no Algfe whilst in Burma, and my knowledge 

 of this Order is extremely slight. The species hero enumerated and arranged were, 

 as stated above, all collected by the late Mr. Sulpiz Kurz. He appears to have made 

 two distinct collections, and to have sent the iirst to M. Martens for deteiTuination ; 

 but the second (in consequence of that gentleman's death in the interim) to M. 

 Zeller for the same pui'pose. The two separate papers by Martens ' and Zeller ' 

 were made over to me by Mr. Theobald for combination, and were found to be 

 arranged on two different systems. Being acquainted with neither, I referred to 

 such botanical works as I had, but failed to discover any one system with which 

 I could bring them iuto agreement. In iact, no two authors appear to agree upon 

 the method of arrangement. In addition to this, I failed to find even the names 

 of some genera of Messrs. Martens and Zeller. It remained for me to combine 

 the two vaiying catalogues to the best of my ability, guided by such aid as I could 

 find. This, accordingly, I have done. The diificulty of this task must serve as an 

 apology for the very unsatisfactory character of the result. — C.P. 



Order DIATOMACEiE. (Brittleworts.) 



A family of Confervoid Algce. Crystalline fragmentary bodies, angular, brittle, 

 flat, usually nestling Id slime, imiting into various forms and separating again ; 

 multiplying by their- spontaneous separation. (Lindley.)

Older CONFERVACEiE. (Confervas.) 



" An Order of Alga=!. Vesicular, filamentary or membranous bodies, multiplied 

 by zoospores generated in the interior, at the expense of their green matter." 



" "VVaterplants, commonly of a green colour, but occasionally olive, violet or red; 

 inhabiting the ocean in some instances, but commonly found in fresh water ; some of 

 them even belonging to both kinds of fluid ; some found in mud, others floating freely; 

 most attached, in some way, on rocks as parasites." — Lindley, Veg. Kingdom. 



species of lichen were brought home from the Southern hemisphere by the Antarctic expedition under 

 Sir James Eoss, ami ahuost every one of these was ascertained to be also an inhabitant of the Northern 

 hemisphere, and most of them European," p. 391. Again ; " It is a remarkable fact that Dr.'" (now 

 Sir Joseph) " Hooker has been able to identify no less than a fifth part of Antarctic alga? (excluding 

 the Xew Zealand and Tasmanian groups) with British species. Yet there is a much smaller proportion 

 of cosmopolite species among the Alg;c than among the terrestrial cellular crjptogams. such as lichens, 

 mosses, and Hepaticie."' The con-ectness of this last observation, I think, niay be doubted.— C.P.
