Calceolaria, plants raised from seed, called common mixed a plant under net, & spontaneously set its own pods—

Six flowers fert. by pollen of own flower & six by pollen of a distinct plant of same general appearance in greenhouse.— owing to minuteness of seed, & adhering to capsule I could not compare quantity carefully in the two lots; certainly not much difference

Aug 9th 7° 30' P.m — planted in sand in same glass—

Aug 14th 2° 30' P.m one of the crossed seeds just cracked shell.—

— 16 7° 30' A.m. one of the uncrossed seeds has just split. (Interval 1d + 15h.)

But case unsatisfactory — one cannot judge from one out of thousands of seeds foolishly planted; & more of crossed seed by a [illeg]accident were sown than of uncrossed — 4° P.m a second uncrossed seed. = Aug. 18th

One of uncrossed seed has germinated far more fully than crossed of which 2 or 3 seeds have only cracked shell

18th 3° P.m. In uncrossed 3 seed fairly sported one in 2/10 of inch high, & of crossed, though much more numerous, as one has just escaped out of seed-capsule. Uncrossed certainly have an advantage in germination. (over

(Calceolaria)

Aug 22d 3° P.m. a great number of seeds have now germ. in both lots & formed cotyledons; by holding up to light both lots in as nearly equal a state as possible; if any advantage the uncrossed have it & so I picked up one or two tallest: now planted on each side of same pot & placed in greenhouse. —

Sept. 21st By holding pot horizontally I can now see that clump of tallest crossed plants are taller than tallest clump of uncrossed.

Sept. 28 —The largest leaf of crossed here shown & some others very nearly as large — largest uncrossed also shown — Considerable difference.

[Figures] Crossed crossed Uncrossed uncrossed

Oct 14th Largest leaf on largest crossed plant is now 1.8 inch long & largest of uncrossed only 1.05 long; & several crossed plants have larger leaves then this. —

(Nov 14th. The difference is now more conspicuous, for largest crossed leaf is 2.9 inch & of uncrossed only 1.9.)

(Dec. 30' Crossed finest plants.)

(Feb 10th. crossed tallest & finest.)

(March 31 Plants look bad too confined — almost equal in size & vigorous)

May 1' do. (Now placed in large pot)

(June 3d. — The plants were turned out without disturbing ball on May 1' into much larger pot, but still look very unhealthy. The crossed plants, however, alone have thrown up 3 flower stems, one of which the tallest is 12 inches high; but flowers miserably small. —)
