 thp.t are most needed, and in many cases are figured and described 

 under a vTonr.- name, and as these names and descriptions are more 

 or less coried in the later monogrcphs alluded to, without inves- 

 tigation as to v/hether they represent the plants Linne, Ha^^orth 

 or Alton intended should beer those names, there are many cases 

 v/here the srecies described in these monop-raphs are quite v:rongly 

 named. A consnicuous instance of this may be cited in the case 

 of v., glomeratum, ^irin., which as figured or described by 3alm 

 ^/■cV, Son^^er and Berber, is not th^'t srecies at all, but is i-. 

 riol'''anthon, Haw., v^hile the real i-. glomeratum, Linn., is the 

 plant those authors have as M. ros^um, '■"ind. The corrected 

 ■ svnon^rmy o:'' ■'■hese snd many others will be riven hereafter under 

 the respective f?enera to which I refer the species. 



"^e division of Mesembryanthemura as hitherto understood 

 into nevr r^enero renders it necessary to consider and decide which 

 of the species known to Linne should be accepted as being typical 

 of the genus, that is, those which best accord with the characters 

 assigned to this genus by Linne. 1'his is not quite a simple 

 matter, ps the follOT"in'^ will demonstrate. 



"fhen establishinp- this penus Linne rlaced it in his Glass 

 3cos«^ndris (i.e., with numerous starrens), and the Order ^entagynia 

 (i.e., with five styles or stignie.s) . . .In his '^enera I'lantarum, 

 ed., 5, n. 215 (1754), and ed. 6, p. 252 (l767), he characterises 

 the genus -'esembryanthemum as follows* — Calyx half-5-fid (i.e., 

 5-lobed), persistent, ^orolla monopetalous ; petals "verj numerous, 

 in several series, with their claws slightly united. ■Stamens 

 numerous, as long as th'e celyr.. Ovary belo^w the receptacle 

 (i.e., inferior), crowned with five obtuse angles; styles usually 

 five, snbul-'^te, erectly reflexed, stigma. s simple, ^apsule fleshy, 

 roundish, marked v;ith five umbilical rays, and with as many cells 

 as there are styles. Seeds many, rounded 1 



At the end of the generic characters ^inne remark.s in italics 

 that "The number is not constant, some have a four-fid calyx, 

 with four styles; others have ten styles." Such remarks were 

 al"'a""'s added by him to indicate species that diverged from \\'hat he 

 considered to be essential cheracters of the genus. 



It should be noted thpt although ^inne and other authors 

 describe the stigmatic organs as tyles, they are really stigmas, 

 being stigmatic to the base. So far as I am aware, a true non- 

 stir^iptic st-<rle is not present in any of the species knovm to 

 Linne. N, "S, Brown

232 Unon analysing the Linnesn characters as applied to the spe- 

 cies linne enumerates, it becomes evident thr^t there is some in- 

 conrruitv in his definition and that he could not have prorerl;/ 

 eranined the s^^ecies he described. Because the only species that 

 can be taken into consider?; tion in the selection of a type for the 

 genus are the thirty-f 've enumerated in the first edition of his 

 Species nlantarum. nublished in 1753. If these species are exam- 

 ined and comnered with his generic chari^icters in the endeavour 

 to determine which of them should be accepted t- constitute the
