[B23]

May 20th 1865 - Six seedlings have flowered from peloric Antirrhinum "Wonder" by own pollen & all these 6 - have 6 sepals 6 petals & 6 stamens with short pistil & long tubular corolla, are all red with orange mouth - I raised many seedlings but they were tender & all died in open ground, except 2 & except the above six which were potted. The crossed seedlings, but few died.

The two which were kept out of doors were likewise peloric, so that altogether (8) seedlings have been raised & all these have all their flowers peloric.

The peloric flowers have their axes forming the same angle with the stem as with

[B23v]

the common Snapdragon & this shews that H. Spencer's view (Biology vol. 2. p 151) on peloric state of Gloxinia is false.

I raised an immense bed of seedlings from common red Snapdragon by peloric pollen & of these I carefully examined the flowers of 64 plants. I also raised 26 plants from the peloric "Wonder" by pollen of common red Snd.

All these plants were alike in both lots & all red. In all there was on upper surface at base a rudiment of a 5th stamen; in most this was so minute that its nature wd not have been recognised, had it not varied in development so that every step cd be traced from minutest rudiment to a stamen with plenty of pollen & nearly as long as the 4 common stamens. But this rudiment has nothing to do with peloric cross; for I examined flowers from 19 common plants & all had such.

It is curious that when both parents are peloric all the seedlings are so, yet that neither father nor mother being peloric produces the least effect on the seedlings
