(Look at Book.) (To be Kept till Spring)

October. — The Dean of Manchester attributes the breaking of the Purple Laburnum (in conformity of with reported origins) to the destruction of the bud, the purple species & the inosculation of the cells. — It is not analogous to Jasmine case. — 17

I saw two hybrids from Azaleas & Rhod. very different in appearance from the same capsule & I think two cactuses from Speciosissima & the Whip cactus (How different in external appearance) Ask again.

Spofforth

[Natural selection, p. 446: "I saw at Spofforth4 two hybrids between Rhododendron & Azalea raised by Herbert from the same seed‐capsule, & they differed greatly in appearance /113/It is, also, an important observation that these lesser variations in the first generation have been principally observed by Gaertner in hybrids between species so closely related that they have been thought by some authors to be varieties, though ranked by Gaertner by the test of fertility, as true species.
4 (At Spofforth, Dean Herbert gardened and experimented with hybrids; see his Amaryllidaceae, p. 359.)"]
