KEVIEW OF THE GENUS NARCISSUS. 31 



Time of Flowering. — The Daffodil leads the way, beginning generally 

 near London early in March, and finishing b.'fore the end of the month. 

 Next in order come iV. iucomparahiUs, N. odorus, N. radiiflorus, N. 

 Macleaii, and the early varieties of N. Tazetta, which are in full flower 

 l)y the end of March, and continue through the early part of April. 

 A third set, N. poeticns. N. biflorns, N. Jonquilla, N. juncifolius, N. 

 Bulbocodium, and the late varieties of N. Tazetta, come out in April, 

 and some of them continue into May ; and three species — N. viridi- 

 florns, N. elegans, and N. serotinus — flower in September. 



On the whole, the character which appears to be most readily 

 applicable for dividing the species into groups, is that furnished by the 

 proportion which the crown bears to the divisions of the flower ; and 

 I intend, therefore, in enumerating the species, to classify them as 

 follows : — 



Group 1. Magnicoronatfe. — Crown as long as or rather longer than 

 the divisions of the perianth. 



Group 2. Mediocoronatce. — Crown half as long as the divisions of 

 the perianth (in one or two exceptional cases three-quarters as long) . 



Group 3. Parvicoronatce. — Crown less than half as long as the di- 

 visions of the perianth. 



Q-roup I. MAGNicOEONATiE : cTOwn as long or ratJier longer than the divisions 

 of the perianth. 



Of the Narcissi which have the crown in the middle of the flower 

 as long as the divisions of the flower, there are only three well-marked 

 species, each of which corresponds to a genus of Haworth's, two of 

 which are well known in cultivation, but the third, which is very rare 

 in a wild state, is now, we fear, lost from our gardens. They may be 

 distinguished from each other as follows, viz. : — 



Tube inversely conical, varying from as long to 



twice as long as broad, with the stamens from 



the bottom ; divisions of the flower more or 



less distinctly ascending. 

 FUaments and style straight ; divisions of tlie| ^ bulbocodium (Genus 



perianth linear- anceolat<), a line to an eighth \ Corbularia, Haworth). 



01 an inch broad at tiie base. J 



Filaments and style curved ; divisions of the 1 ^ Pseudo-Naecissus 



perianth oblong-lanceolate, 5-6 lines broad at \ ' ^q^^^^^j^^ Hawortli). 



Tube cylindrical, rather widened at the top five J 3 q^^^tuinus (Genus 

 or SIX times as long as broad ; divisions o( the ^ j_,,aracus, Haworth) . 

 perianth distuictly rcllexed. J
