THE NARCISSUS. 



81 



Hybeids. 



The hybrid kinds of Narcissi, as a rule, are very easily recog- 

 nised by their structure. The medial insertion or adherence of 

 their stamens is very marked and characteristic. Practically all 

 the medial Narcissi are of hybrid origin. Any one who once 

 obtains a clear notion of the differences between a true Daffodil 

 and a true Narcissus in this way will have no great difficulty in 

 determining the hybrids of the genus. Here, for example, 

 are descriptions of the flowers of the six great type-species of 

 Narcissi. 



1. N. Pseudo-Narcissus 



2. N. poeticus . 



3. N. Tazetta . 



4. N. Bulbocodium . 



5. N. Jonquilla 



6. N. triandrus 



| St: 



in one set or 



series. 



( Stamens inserted near the mouth 

 I of the tube ; in two series. 

 Ditto, ditto. 



(Stamens basal; very slightly 

 i biseriate ; decimate. 

 | Stamens near mouth of tube ; 

 i biseriate. 



f Stamens biseriate ; heteromor- 

 1 phous. 



And here for comparison are descriptions of some of the prin- 

 cipal hybrids between the above wild species, viz. : — 



N. incomparabilis 



N. montanus . 



N. Macleayi, N. Sabini 



N. odorus 



Stamens in one series ; filaments 

 springing free at about two- 

 thirds the length of the narrow 

 tube. 



| Stamens medial ; very slightly 

 i biseriate. 



j Two-seriate ; medial (more basal 

 1 in Sabini). 



Slightly biseriate; medial in- 

 sertion. 



N. Johnstonei, N. tridymus One-seriate ; medial. 



N. Tazetta orientalis . Biseriate ; filaments all elongated. 



The filaments in true Daffodils spring free from near the base 

 of the flower-tube.
