This is a very interesting as well as beautiful plant, so 
closely resembling some states of the Himalayan Amphicome 
arguta, that had it come from India it might hastily 
have been put down as a slight variety of that species. A 
comparison, however, with another very closely allied 
Turkestan plant, Incarvillea Olge, Regel (Gartenfl. 1880, 
p. 8), suggests that it may be a link between Amphicome and 
Incarvillea, and indeed help to unite these genera. The 
generic characters of the two are, that Amphicome is 
perennial, with the wings of the seed split up into fine 
hairs, whilst Incarvillea is strictly an annual, with the 
membranous seed-wing quite entire. Now I. Olga is 
described by Regel as probably biennial, and having an 
oblong entire membranous wing to the seed; and J. Koop- 
mannii is described by Lauche as a shrub with flat winged 
seeds. Thus the difference between these genera is reduced 
to the condition of the seed-wing, which assuredly does not 
coincide with habit, for that of the two Turkestan plants is 
very unlike Incarvillea and wholly that of Amphicome, as a 
comparison with A. Hmodi of our plate 4890 shows. It is 
NOVEMBER Ist, 1881.
