Salvia coccinea (2 Plants)

20 flowers crossed. 26 self-fert. own flower pollen.

(Aug. 25 (A Some plants under net has set spontaneously a good many seed.) of which 76 98 calyces pods were gathered, yielding average of of 1.45 [x] 2 [=] 2.90 seed; this is less than half average of flowers artificially self-fertilised, which shows that fertilisation was well effected.

The 20 crossed flowers yielded 18 pods. ie 90 per cent.

The 26 self-fert. flower [do] 23 pods ie 88 per cent —

The 18 crossed pods no pods contained 57 seed ie average of 3.17

The 23 self pods contained 76 seed ie [do] of 3.30.

So that the self the most fertile!

The 57 crossed seed weighed 1.51 gr ∴ 76 seed wd weight 2.05 gr

The 76 self seed weighed 1.99 gr.

Hence equal numbers of self- seed weighed 97 per cent of crossed seed.

Hence crossed have very slight advantage in number of capsules set & in weight of seed, but a disadvantage in average number produced

(May 24 /68/ Plants about 3 inches to tip of stem, & crossed seem to have slight advantage.)

(July 6' 68 — Plants 2/3 grown) — Two Highest plants, measured on each side

Aug 23 Flowers almost all withered & producing seed

(In all 3 Pots the Crossed flowered first.)

(All the crossed pl. produced 409 flowers. All the self plants produced only 232 flowers.—)
