perfectly hardy in our climate, than this species, and it should 

 be in every flower border. Only four or five species and varie- 

 ties of this extensive and showy genus of plants are grown in 

 our gardens at present; but we hope soon to add many more of 

 the fine ones which exist in English collections. Equally hardy 

 and equally beautiful, they should be generally known and culti- 

 vated. [Bot. Reg.., March.)

NUTTA'LLM (after Mr. Thomas Nuttall, a writer of the Systematic Botany of North 

 America.) 

 cordata ii/n//. neart-^earerf Nuttallia. A (?) perennial plant; growing a footer more in 

 height ; with pale rosy flowers ; appearing in autumn ; propagated by seeds ; a native of 

 Texas (?). Bot. Reg., 1938. 



A very beautiful species of this genus, dedicated to Mr. Nut- 

 tall by Dr. Hooker. Mr. Drummond collected the seeds of 

 this species, we believe, in Texas, and transmitted them to the 

 Glasgow Botanic Garden, where plants were raised, and distri- 

 buted to several gardens. The habit of the plant is neat ; the 

 flowers are of a pale purple or rose color, and are produced on 

 long terminal peduncles. Unfortunately the specimens from 

 which the drawing was taken were mislaid, and, consequently, 

 no description of this species could be given. Whether it will 

 prove hardy in our climate is doubtful. It merits, however, to 

 be introduced. (^Bot. Reg.., March.)

PERE'SKM 

 aculeata £>e Can(7. syn : Cactus Per^skia L. West Indian Gooseberry. A green-house 

 plant; growing two or more feet high; with white flowers; appearing in October; 

 propagated by cuttings; a native of the West Indies. Bot. Reg., 1928. 



This is a plant which is in many of our collections, but which 

 has seldom or ever flowered. Unlike the other cactaceous 

 plants, it has fully formed leaves, of a large size, and the plant 

 forms quite a bush when properly and successfully cultivated. 

 In England it is used as a stock on which to graft other kinds. 

 The flowers, though not possessing the brilliancy and splendor of 

 the well known and more popular plants of this order, are, however, 

 not unhandsome. " They form fine clusters of white and green 

 cups, and the fruit is like a mellow gooseberry." Dr. Lindley 

 remarks, that " the woody matter of the stem is one of the best 

 illustrations that physiologists are acquainted with of the plan 

 on which exogenous trunks are formed. This is easily seen by 

 taking an old stem of Peresk/a aculeata, and macerating it for a 

 few weeks, when the whole of the horizontal cellular system de- 

 cays, leaving behind it the longitudinal system, in the form of a 

 woody skeleton." The drawing was communicated by W. 

 M. Christy, Esq., of the Clapham Road, in October, 1833.
