1. Hymenocallis occidentalis (Le Conte) Kunth. Spiderlily. Map 674. 

 The spiderlily grows in low woodland that is usually inundated each year 

 and in soil which is comparatively free from organic matter and which 

 becomes very hard during the summer months. The bulbs are usually 6-9 

 inches below the surface in a compact, blue clay. It is rather frequent in 

 the southern part of Posey County where its habitat is frequent and local 

 elsewhere. It is found in the Big Creek bottoms near Wadesville, Posey 

 County, local in the bottoms along Pigeon Creek in the northern part of 

 Warrick" County and the southern part of Gibson County, and local in its 

 habitat along Little Pigeon Creek in Spencer County. It doubtless has a 

 range wider than the location given above, but, as I understand its habitat, 

 it will be restricted to the peculiar low places along streams and low spots 

 in woods of the southwestern counties. Where it is found it is compara- 

 tively abundant. 



In a restricted habitat southw. from s. Ind. to Ga. and Mo.
