NARCISSUS POETICUS AND ITS ALLIES 91 
has not yet been accumulated to enable many of them to be 
separated as species or a a as varieties under others with any 
great degree of confidence. I therefore think it will serve the 
most useful purpose in ‘this paper to maintain, as a tentative 
measure, such species already described as seem to be plants clearly 
separable from each other in apparently important characters, 
and to give specific rank also to any other forms that may seem 
equally distinct. This involves the recognition of several of the 
species of Haworth. 
The most definite means of segregating this group of Narcissi, 
and the one most generally pst arn in modern botany is that 
he by i (Syn. Fl. Germ. /. c.), in which two species are 
rst, N. coariene: be is diagnosed as a plant with 
ae ssi Fore -segments, a flat corona, three stamens included in 
chief biccdaehaisivn: 
Of the two plants described by Koch it will i seen that his 
N. poeticus agrees in its flat corona with the N. to-purpureus 
precox of Parkinson and Gerard, which is the N. albus circulo 
purpureo of Bauhin’s Pinaw, cited for N. poeticus by Linngeus, who 
likewise — the 70 or rotate corona. It is also identical 
with N. poeticus Salisb. in Hort. Trans. i. 365, vehi aut

confirmed by figures 1 and 2 of the pints of this paper, which hay 
been rope ean from Salisbury’s own drawings of his iiecdalie: ; 
and the plant itself, which the older British authors described 
from the garden and Salisbury received from Montpelier, may 
still be obtained in Ireland for comparison 
In the case of N. radizflorus Koch’s description and Salisbury’s 
original brief diagnosis in his Prodromus offer no essential con- 
ictions. Its floral charac 
already mentioned. Koch cites several Austrian stations for 
N. raduflorus, which, although familiar to English Serene! “ 
the eighteenth century, was not anpeoed cultivated her 
much earlier date. It may possibly be the N. pee ec nie 
ico nian of Gerard, but of plants with stellate towers
