In my previous account of this genus in The C-p^deners' Chroni- 

 cle, as above ouoted, I was not sure of the correct identity of 

 G. nustulatiim, becfiuse I had not then seen any specimen of definitely 

 knov.'n to come from, the region of Port Elizabeth -division, where 

 Burchell found it. But nov: that Dp, Muir has sent me plants from 

 that area which are unquestionably G. nustulptum, I find that (as 

 mifrht be exT>ected from its being a native of that well explored 

 region) it is not uncommon in cultivation, and that beyond doubt is 

 the same as '^. longiim, although neither ^illenius, De Cgndolle nor 

 haworth mention or figure the nustule at the base of the leaves, 

 b't as it is often not very consnicuous unless sought for, and not so 

 distinct in t is country as on na tive-/?rovTi specimens, may easily 

 have been overlooked by them, or considered to be of no specific sig- 

 nificance at the period (l795) when ^aworth first described the 

 species, for the r)URtule was not noted as a character of any species 

 of this genus until tvvrenty-four years later, when G, pustulatum v;as 

 first descrlbecl . ^nienius and ^e Candolle represent the pedicels 

 as being 2-f?-3 inches long, and this, in my experience, is unusual, 

 and must be due to some condition of cultivation. 



It is somewhat rem-arkable that '^evjovth seems uncertain of his 

 identification of Hi longum., and must certainly have had two diff-
