Mr. T. A, KNIGHT on, esculent Strawberries. 363 
berries were planted in pots, in different successive seasons, for 
the purpose of experiment :—the common wood, the white alpine, 
tbe Duke of Kent's, or wood-strawberry of Canada, the common 
scarlet, the Bath scarlet, the pine, the black, the white Chili, and 
the hautbois, with some others which proved to be varieties of 
the common scarlet, but to which no particular name had been. 
given. The pollen of the Wood-strawberry was introduced into 
blossoms of the White alpine, from which the stamina had some 
days previously been extracted in an immature state. Abundant 
seeds were produced, which afforded offspring generally similar to 
their male parent in taste, flavour, and colour. 'l'he wood-straw- 
berry of.Canada, the common scarlet, the Bath scarlet, the pine, 
the black, and the white Chili afforded under similar circumstances 
abundant offspring, however crossed, and the offspring presented 
every intermediate shade of character between these varieties ; 
but none of them would intermix with the wood or white alpine. 
The Hautbois did not breed with any of the preceding varieties, 
except in one instance with the Bath scarlet, from the seeds of 
which 1 obtained plants which proved apparently to be mules. 
. I preserved these several years, in which they made feeble and 
always abortive efforts to produce blossoms. In external charac- 
ter all of these a good deal resembled the hautbois in foliage and 
general habit; and two of them were not readily distinguishable 
from plants of that species. — 
_ The preceding results, therefore, lead me to conclude that our 
gardens contain three, and three only, distinct species of straw- 
berry, one of which has sported very widely in varieties. 
= ] much wish that some members of this learned Society would 
make experiments, similar to those above stated, upon the diffe- 
rent species and varieties of plants now comprehended within the - 
genus Rosa, Salix, Pelargonium, and others. Many of the sup-
