Amaryllis. 123 



cling round the ovary in a compact body, so com- 

 pletely fill up the whole space within the perianth, 

 that no opening is left except a very narrow passage, 

 frequently merely a tiny hole or a minute fissure. 

 Through such openings invited guests can introduce 

 their proboscis, while unbidden ones are completely 

 excluded from the nectar. Such an arrangement is 

 found in very many Leguminosae (Trifolium, Lotus, 

 Anthyllis, Hippocrepis, Onobrychis, Medicago, etc.), 

 where there is merely a SEaaU triangular aperture 

 on the right and left of the upper filament near -the 

 bottom of the flower (Plate I. fig. 33, Hi'ppocrepis 

 comosa, seen from above, after removing the standard). 

 Such again in the genus Viola, consisting of flowers 

 too well known to require further description; such 

 also in the magnificent large-flowered species of 

 Amaryllis. The structure of the latter, so far as 

 we are at present interested, wOl be understood 

 by reference to the drawings of Amaryllis lella- 

 dorma, which I have selected for illustration (Plate 

 I. fig. 39, transverse section of flower; fig. 38, longi- 

 tudinal section through nectary). The perianth of 

 this flower, not far above its base, gives off an 

 outgrowth, which in shape of a broad band encloses 

 the bundle formed by the style and the six thick 

 and closely approximated filaments. Only at one 

 point, on the upper surface of the bundle, does this 

 outgrowth, that elsewhere is in closest contact with
