Lobelia erinus Gard. Chronicle says is var of Lobelia ramosa (var. snowflake.)

4 Plants in too small separate pots, separate pot under net, late on autumn & did not set well; but I got 1 pod from a cross & 2 pods from artificially fert. with own pollen. The latter contained by eye rather more seed than the one crossed pod. — Did not

Oct 27' 6° P.m. placed on sand. Nov. 2d 6°. P.m some of both lots have cracked their shells, & the crossed have a little advantage rather more of them being cracked.

(Nov. 4th certainly the plumu radicles of crossed seed are now more fully protruded than in any of uncrossed.)

Pot. I seeds were sowed on both sides, (but did not germinate well)

Pot 1. all equal. — March 31. crossed rather finest

In sand, the crossed perhaps the healthiest.

March 31' 1867 Pot 2. Hot house — Plants coming into flower — The 2 tallest crossed plants about 1 1/2 inch taller than 2 tallest self-fert. plants.

(In Pot I, III & X. The crossed plants flowered a few days before the self-fert; I believe this was so in Pot. II.; but fact not recorded at the time]

June 25 I now find that almost all the but not quite all) crossed plants produce plenty of pollen; but nearly all a good many of the self-fertilised plants are utterly destitute of pollen; the anthers generally do not cohere (case like Dianthus)— N. B in both D. & Lob. some few of crossed plants may by accident have been self-fertilised).

Lobelia ramosa (snowflake) 1867

On crossed plants of 1st gen. some flowers were crossed & produced 5 pods, (one so bad thrown away, & these 4 contained 0.57 gr. of seed ∴ 6 pods wd have contained 0.85 gr.

On some self-fert. plant, some were again artificially self-fert. & they produced 7 pods (one so bad thrown away) & the 6 pods contained. 0.51 gr. of seed.

Therefore equal number of crossed & self pods contained seed by weight as 100 to 60.

The plants from these seeds will form second generation.

(Feby 14 1868 The seeds were placed in damp sand in two glasses & the crossed seed in both certainly germinated much earlier & more freely than the self-fertilised seed. — In Pot IV. smaller pot. seeds crowed.)

(April 3d /68/ In Pot. 1, 2, 3, Plants about 1 1/2 inches high, (3 or 4 plants on each side) & equal. — But in Pot IV, in which plants were left crowded the crossed are about one-third taller than self: good proof of effects of crowding struggle on result. —)

(April 23d Pot. IV crossed 5 inches on average high— selfs 4 inches high & do not look nearly so fine plants— In other pots the crossed have now decided advantage. — between about 4 inches in height —
