Facts and Considerations which have a general Relation to Floriculture. — 

 Certain species of plants, which, under artificial culture, are usually feeble, 

 may be much invigorated by watering them with a decoction of other more 



abundant and robust species of the same genus. This was told to me by 



Forster, Esq., to whom the idea had first (if I have remembered rightly) 

 arisen ; and who had, by watering the delicate iSkxifraga cernua with a decoc- 

 tion of S. granulata, promoted very obviously vigour in its growth, and increase 

 in its size ; and the like effect had been produced upon yidiantum fapillus 

 Veneris, by watering it with a decoction of Pteris aquilina (I think), or 

 some other abundant species of fern. — J. D.

POLYPETALOUS DICOTYLEDONOUS PLANTS. 



IV. PapaverdcecB. 



ESCHSCHO'1/TZ.TJ crbcea Benth., on which we have quoted information in p. 171., is figured in 

 the Bot. Reg. for June, t. 1677. 



Two plants, in the garden of the Horticultural Society, are all that at pre- 

 sent exist in Europe. In consequence of its bleeding copiously when wounded, 



it is not likely to bear propagation in any other way than by seed It has 



not hitherto produced any seed in Britain. When the sun shines, the petals 

 unclose, and, by their rich colour and velvety lustre, produce an effect which 

 is, for brilliancy, unrivalled in the flower-garden. (Bot. Reg., June.) 



PLATYSTE v MON californicus Benth., respecting which particulars are quoted in p. 170., is 

 figured in the Bot. Beg. for June, t. 1679. 



" The few seeds it produced have failed to vegetate ; and the species is, 

 therefore, lost to our gardens." Dr. Lindley has given, in the place cited, a 

 pleasing speculation on the natural affinities of this plant.

 " It is nearly related to the A. glauca of the south of Europe, but is very different in the form of 

 its leaves." 



" Very common in Chile, whence we have had many specimens gathered by 

 various collectors. Mr. Bridges sends it under the name we have adopted ; 

 adding, that it is called by the Chilenos ' Oreja de la Zoera ; ' and that it is 

 an herbaceous plant, found in stony places near Valparaiso and Quillota. 

 The plant is hardy enough to bear our climate, if protected from wet and 

 the severest cold in winter. It is figured from the collection of Robt. Bevan, 

 Esq., Rougham, near Bury St. Edmunds, Suffolk." (Bot. Reg., June.)

An interesting species in its slender twiggy habit, bright brown colour of 

 the bark of the older branches, breadth and size (for the genus) of the leavesj 

 and the heads, each, of numerous flowers, which crown the tips of the branch- 

 lets. " It has much of the habit and strength of growth of P. /igustrina Lab.
