Note on the Fertilisation of Aspidistra elatior by Slugs. By

(Read 10th January 1889.) 

 The flowers of this very common decorative plant rise 

 from subterranean rhizomes, and open immediately above 

 the surface. Their bases are often half sunk in the soil, 

 and they have frequently been mistaken for fungi by the 

 uninitiated. In large plants, under artificial cultivation at 

 least, many of the crowded rhizomes lie above the surface. 

 Protection is afforded the flower by a series of papery bracts 

 (fig. 1, &r). The hue of the interior of the perianth is brownish- 

 purple, the upper inner edges of the 

 lobes being orange. The outside is 

 freely spotted with purple. The 

 stigma (fig. 1, r) roofs over the whole 

 throat of the flower, and is dingy 

 reddish-purple. It is deeply sulcate, 

 the eight sulci (fig. 1, s) radiating with 

 considerable regularity from the 

 centre. They terminate near the 

 centre in small hollows or tunnels, 

 which, having usually yellow areas Fig. l— Section of Flower of 



at the endings, are suggestive of Aspidistra elatior, nat. size.
