What a fascinating article! (v34 p122)
I was intrigued by Baroni's comment that the species all appeared to be infertile at first, but his patience eventually paid off.
"When the plants first came here all were completely sterile, and I lost all hope of fertilising and hybridizing them. But little by little some of them showed the lost quality of seed-bearing, and finally some new importations from Central China made it an absolute certainty that iut would be possible not only to grow seeds but also to hybridize the plants, and now the result is very promising, and we have some fine hybrids."
