the florists has been busily employed, and as a recompense 

 for patience and skill, the most superb varieties have been 

 obtained. Exceedingly valuable collections are common 

 among us. We accordingly, in a brief manner, notice under 

 green-house cultivation, the instances of Rhododendrons and 

 Azaleas, (the latter have been comprehended under the 

 generic distinction of the former by botanists,) in the pos- 

 session of M. P. Wilder, a hundred or more, some of great 

 rareness, — of S. Sweetser, upwards of an hundred : and 

 numerous others, which have not come under our observa- 

 tion. A gorgeous plant of R. hybridum, belonging to the 

 former individual, exhibited nearly one hundred flower buds. 

 Another fine plant of the same, in the green-house of T, 

 Mason, displayed fifty heads of flowers. iVt the conversa- 

 tory of J. P. Gushing, Watertown, a noble plant of R. 

 arboreum produced nearly seventy trusses of bloom. 



Those anomalous and leafless vegetables the Cacteag have 

 many representatives of their several genera and species. 

 Of these we mention a fine group belonging to S. Sweetser, 

 considered the most complete, besides others of extent in the 

 possession of Col. Wilder, of the Messrs Putnam, of J. P. 

 Gushing, at the Botanic Garden and elsewhere. Rarer kinds 

 are met with, in almost every structure for plants. Generally 

 of easy growth, (though a few need the stove) and of mag- 

 nificent appearance in bloom, they have become extensively 

 cultivated. Twice within the past year has the Gactus Tri- 

 angularis flowered, one specimen at J. P. Gushing's, under the 

 management of D. Haggerston, and another in the possession 

 of J. W. Boot, Boston. Of rare occurrence, these instances 

 are worthy of note. Echinocactus Eyriesii, has flowered in 

 many collections. A plant belonging to Mr. Leathe of Cam- 

 bridgeport, gave three or four flowers. Gereus phyllan- 

 thoides, has been considered unworthy of further culture by 

 Mr. Haggerston, by whom it has been bloomed.
