Ononis minutissima 1867 from seed from Mr J. Traherne Moggridge.

~~Some~~ 8 or 10 perfect flowers were crossed with pollen from perfect flower on distinct plant, & produced 7 capsules, (but one may be rejected as it contained imperfect seed). The 6 capsules contained on average 3.66 seed, max. 5. min 3.

12 Perfect flowers were marked, but not touched, so were spont. self-fertilised & produced 8 pods, containing on average 2.38 with max of 3 & min. of 2.

(53 capsules were collected formed by the closed, imperfect flowers & these contained on average 4.1 seed; & the seed looked finer & plumper than even the crossed seed.)

Jun 1' 1868 seed placed on sand to germinate.

(July 8 68 — Crossed & self-fertilised Plants equal 4 1.2 inches high)

July 23. 1868 The comparison is between perfect flowers crossed & spon.t fert. imperfect flowers.

Oct. 25 1868 One crossed flowered before any self

June 5th 1869. I see there are 2 Plants each side
