 bus et rectis vel subrectis (non torquatis ut in M.jiori' 

 bundo) ramulis patulis; foliis forsan minus viridibii s; 

 at nihilominus pone id locarem. 



Obs. Folia summa incipientia saepe obsolete trigono- 

 cylindracea, sive supra planiora vel depressa. 



Obs. Under this Section of the present Genus it is 

 appropriate to remark that M. hispidum « & /3 of 

 Revis. PL Slice, p. 186. are two distinct species, easily 

 separated by the following characters. 



hispidum. M. (hispid-peduncled): foliis cylindricis obtusissimis 

 calyceque glabro obconico viridibus papuloso-micanti- 

 bus, staminibus pistillo longioribus, ramis pedunculis- 

 que hispidis. — M. hispidum u, 1. c. 



subhispidum. M. (smooth-peduncled) : foliis cylindricis obtu- 

 sissimis calyceque glabro fere obconico subviridibus 

 papuloso-micantibus, ramis plerumque et pedunculis 

 omnino depilatis. — M. hispidum /3, 1. c. 



Ofo.Priore elatius,longe minus ramosum,?a??22s longi- 

 oribus erectioribus strictioribus, distantioribus gracilio- 

 ribus et florentibus fere semper denudatis vel aliquan- 

 tillum furfuraceis. Folia (uti calyces) minus papuloso- 

 micantia, et minus intense viridia. Petala dupl5 la- 

 tiora seu minus cuneata, longe pallidiora, costa basi 

 subinde albicante, apice altius emarginata. Staviina 

 stylos subgequantia, pallidiora breviora minus expansa, 

 at crassiora, uti unthercc itidem pallidiores. Capsulce 

 angulis maturis, longe minus productis, et olitusi- 

 oribus. 



Obs. Professor DeCandolle, in his Prod. v. 3. p. 441, 

 under his M. tuberculatum, cites my M. hispifolium 

 as synonymous, saying " foliis acutis papulosis molli- 

 bus" &c. — but my plant in its var. a, has folia valde 

 oblusa pilis respicientibus tecta: and in its var. /S, 

 which is twice as large, is rather less obtuse-leaved, 

 but by no means acute. Can M. DeCandolle's plant, 

 therefore, be my M. hispifolium /3 ? or, are the three 

 distinct? My /3. I have known forty yeai's in Chelsea 

 Garden ; u. only seventeen years. 



Obs. 2. Closely allied to this species may appropri- 

 ately be briefly added, for the first time, an account of 

 the rare flowers of M. candens. Nob. Revis. PI. Succ. 

 186. and of a new variety of it from the Prince of Salm- 

 Dyck, as follows : 



catidens.
