REVIEW OF THE GENUS NAUCISSUS. 113 



juncifolius, but is much more robust in general habit, with larger and 

 more numerous flowers, and a crown considerably shorter in proportion 

 to the divisions of the limb. We have never seen any variation of the 

 colour, which is a beautiful bright yellow. It is, perhaps^ the most 

 fragrant of all the species, and is often seen with double flowers in 

 gardens. 



XVI. N. BiFLOuus (Curt. Bot. Mag. t. 197).— Bulb ovoid, more 

 than an inch in thickness. Leaves about four to a scape, f-y in. 

 broad, slightly glaucous, flattish, bluntly keeled, often more than a foot 

 long. Scape compressed, with two salient edges, bearing typically 

 two, rarely one or three, flowers about the beginning of May near 

 London. Spathe about 2 in. long, usually exceeding the pedicels. 

 Tube about 1 in. long, exclusive of the ovary ; expanded flower 15-18 

 lines across, the divisions milk-white (not so pure a white as in the 

 next), spreading horizontally when fully expanded, |— |- in. long, |— | 

 in. broad, obovate, much imbricated, blunt or cuspidate ; crown 1-1|- 

 line deep, less spreading than in N. poeticus, yellow, about ^ in. across, 

 the edge conspicuously crispato-crenulate. Anthers sessile, uniseriate 

 at the throat of the tube. Eiig. Bot. t. 276 ; Eed. Lil. t. 405; Kunth, 

 Enum. v. p. 733 ; Eeich. Ic. t. 810. — N. poeticus, Huds. N. cotliur- 

 nalis, Salisb. Prodr. p. 225. N. triJJorus and N. diantlms. Haw. Mon. 

 p. 14. 



Though this is said never to perfect its ovides and pollen, it is very 

 common as a wild plant, has become naturalized in abundance in many 

 counties of Britain, and is distributed on the Continent, through 

 France to Switzerland, Italy, and the Tyrol. Greuier and Godron 

 (Fl. France, iii. p. 257) describe an intermediate between this and 

 Tazetta, under the name of Tazetto-poeticns, with smaller and more nu- 

 merous flowers than in N. bijtorns, and a longer, deeper-coloured crown, 

 which is the N. bijlorus, var. hybridus, of De CandoUe's ' Flore 

 Fran^aise ;' and Dr. Henon, who made, during many years, a special 

 study of the French Narcissi, writes as follows : — " The station of 

 Lattes, near Montpellier, is remarkable in that it off"ers many species 

 mixed in the same meadow {N. poeticus, angustifoUus, bijlorus, Tazetta), 

 as well as a considerable quantity of intermediate forms, varieties, or 

 hybrids. In ISiO, along with MM. Dunal, Delile, and Bouchet, I 

 asserted that at this station might be seen all the passages from 

 poeticus to Tazetta, passing through bijlorus without any appreciable
