This species is mainly distinguishable from Guianensis 
by the shortness of its tube, which does not equal the limb, 
while that of Guianensis is preposterously long. It is tender, 
but not so difficult to manage as Guianensis. I had from 
Mr. Griffin the very ovata figured in the Register, but 
there was very little to distinguish it from Amoena, but rather 
broader and less erect foliage, and the seedlings raised from 
the two plants could not be distinguished. Var. 3. was 
raised at Spoff'orth from seed of var. 1. and has long, erect, 
lorate leaves. The circumstance is very singular. The 
plant had been deprived of its pollen for an experiment, and 
touched with pollen of another and hardy genus ; but some 
particle of its own pollen must have escaped, as frequently 
occurs, in the operation, no other Hymenocallis having been 
in flower at the time. Seeds were produced, very imperfect 
in their appearance, small, and discoloured. Four seedlings 
were raised, all exactly alike, and having the appearance of 
a different species from the parent. I entertained doubts at 
first whether a bigeneric mule had been obtained, but the 
plants had not inherited any hardiness from the supposed 
male parent, and when they flowered the inflorescence dif- 
fered in nothing from that of Amoena. Does this remark- 
able occurrence exemplify the manner in which permanent 
local varieties are produced by peculiarities of temperature, 
soil, or situation, or by an insufficient quantity of the pollen? 
I am confident that no other species was in flower at the 
time ; but, supposing me to be mistaken in that point, if the 
seedlings had been produced by the pollen of H. expansa, to 
which they approximate in foliage, the form of the flowers 
must have been affected as well as that of the leaf, which is
