Jun 24th 1863 Salvia Tenori

over

Fertilised 5 flowers & marked with white threads — others untouched. (saw many Hive Bee visiting open plants & bringing out anther)

July 9th fertilised 3 flowers— (2 on one stem) white wool, with pollen of tall blue Salvia. patens? in Flower garden (Dichogamy)

July 15. Every Every flower of plant uncovered had fine seeds. — I examined six spikes under net all the 5 flower which I fertilised produced fine seeds.— On 6 long spikes covered with flowers only one other flower had set, excepting on 3 of spikes 2 or 3 flowers at tops of spike which with wind wd be dashed about, & some of them produced only 1 or 2 seeds!

[88v]

The structure of this flower is essentially like that of blue S. patens, except that the disk is perforated by small hole.— through which bees would have to pass, I presume proboscis & in doing this push down th spring. — (The plate or disk is deeply concave, & longitudinally divided & is formed of two separate portions, united only at extreme margin, & a passage is left between the portions, through which perhaps bees pass their probosces. — Pollen shed in large buds!!

July 29. A branch with flowers almost faded uncovered & left to Bees, produced splendid seed.—
