than a hardy Aconite, with undivided (!) leaves, which are 

 merely crenated, and embrace the stems. It has been intro- 

 duced from Cashmere by the Hon. Court of Directors of the 

 East India Company. The flowers are in loose pyramidal 

 racemes, dull purplish green, and before they expand, there 

 is scarcely any thing to be seen except the round helmet. 



119. EUTHALES ynacrophylla ; caule erecto crasso ramoso, foliis oppositis 

 petiolatis oblongis dentatis, floribus lax^ dichotome paniculatis. 



A very fine herbaceous plant from Swan River, with a 

 stout fleshy stem, 2 feet high, broad deep-green leaves, 6 

 inches long, and large showy yellow and brown flowers. 

 Altogether it grows from 3 to 4 feet high. Flowered in the 

 garden of the Horticultural Society in May and June, from 

 seeds purchased of Mr. James Drummond, and it now seems 

 likely to go on producing its blossoms for two months longer. 



UPON THE COLLECTING HAIRS OF CAMPANULA. 



There are the following very interesting observations upon 

 this curious subject, by M. Adolphe Brongniart, in a recent 

 number of the Annales des Sciences. 



" It has lonsr been known that the external surface of the 

 upper part of the style and of the stigmatic arms of Campa- 

 nulaceous plants is covered with long hairs, which are very 

 visible in the bud, before the dispersion of the pollen, and 

 which are regularly arranged in longitudinal lines in direct 

 relation to the number and position of the anthers. 



" These hairs and their connection with the pollen, at first 

 remarked by Conrad Sprengel in several species of Campa- 

 nula, and afterwards by Cassini, with more care, in Cam- 

 panula rohmdifolia, have been observed by M. Alphonse 

 DeCandolle in the whole Campanulaceous order, with the 

 exception of the small genus Petromarula. At the period 

 of dehiscence of the anthers, before the^ expansion of the 

 corolla, and when the arms of the style are still pressed 

 against each other in the form of a cylinder, these hairs cover 

 themselves with a considerable quantity of pollen, which they 

 brush, so to speak, out of the cells of the anther ; and for 

 this reason they have been named, like the analogous hairs 

 in Compositse, Collectors. 



" At the period when the flower expands, the arms of the
