Floret Jul. Aug. G. H. 11. s. 1? . 



P.S. I avail myself of the present opportunity of correcting 

 the following errors, which time alone has enabled me to 

 ascertain. 



1. Mesembr. deflexum, |3. Revis. PI. Succ. p. 140, is the 

 same as M. imbrica?is, p. 139, and the last is a good and most 

 abundant-flowering species. 



2. M. leptaleon is the young state only of M. retroflexum^ I.e. 



3. M.Jlexile is the young state only of M. polyphyllum, 1. c. 



4. And M. torquatum is a casual state only of M.Jloribun- 

 dum. Revis. PI. Succ. p. 187. 



DeCandolle in vol. 3. p. 416 of his Prodromus, just published, 

 says of Mesembryanthema : " Species plerseque hortenses ex 

 cl. Haworth, &c. — sed forsan plures ut merae varietates ha- 

 bendae." 



But all the new species which I have published, I w T as well 

 and sufficiently assured, were raised from wild African, or 

 Australasian seeds, except the following only, whose origin I 

 cannot trace further than I have printed. M.Jiciforme; 

 M. hybridum; M. nobile ; M. mustellinum ; M. bigibberatum : 

 M. cruciatum; M. Salmii; M. cultratum; M. coruscans; 

 M. procumbens ; M. variabile; M. mucroniferum ; M. loratum, 

 and M. hispifolium. And even seven of the above I received 

 from His Highness the Prince de Salm Dyck, whose genuine 

 origin I believe he can point out. 



In my last communication Phil. Mag. and Annals, N.S., vol. 

 iii. p. 184, 1. 15, for Crassidam undosam, read Crassulam un- 

 datam.
