N. triandrus may be compared with that of other Amaryllids in 
which inverted bundles occur toward the upper surface, as Zephyr- 
anthes candida Herb. (Amaryllis nivea Schult.) (fig. 6). In these 
cases the structure is interpreted as indicating that the limb is of a 
petiolar nature. 
The only plants belonging to the subgenus Eunarcissus in which 
non-phyllodic anatomy has been found are WN. juncifolius Req. and 
N. reflexus Lois.; in these all the bundles are normally orientated. 
This type of structure, however, although apparently rare in

Eunarcissus, is characteristic for the subgenus Corbularia. In both 
N. Bulbocodium (fig. 4) and N. monophyllus (fig. 5) only two series 
of bundles are found, both of which are normally orientated; the 
inverted series toward the ventral surface is absent. 
The interest of the leaf anatomy of Narcissus, from the stand- 
point of the phyllode theory, lies in the fact that within the same 
genus there are examples of phyllodic anatomy (fig. 3), and of a 
reduced form of anatomy (figs. 4, 5) in which the loss of the inverted 
bundles results in a structure to some extent simulating that of a
