510 NOTE. 
the leaves appeared to be arranged some on the outside, others on the 
inside, of an erect hollow cylinder, some six inches in height. The 
oldest leaves were outside, the youngest within, so that the appearance 
presented was as if the summit of the axis had been pushed or drawn 
in, much as the finger of a tight glove might be invaginated in with- 
drawing it from the hand. 
The plant in question thus furnishes an actual illustration of the 
supposititious case mentioned at p. 482. 
Double flowers, see pp. 499, et seq.—The following species may be added 
to those already recorded: Lychnis coronaria, Hibiscus mutabilis, Lotus 
major, Pisum sativum, Godetia sp., Ipomea purpurea, Convolvulus minor, 
Heliotropium peruvianum, Trillium grandiflorum, and Phaius grandi- 
florus.
