THE C.LUBMOSS PAMTLY. 



II. PILLWORT. PILULAEIA. 



Hootstock creeping under water, with subulate leaves almost solitary 

 at the nodes. Capsules globular, almost sessile in the axils of the 

 leaves, divided into 4 cells, opening when ripe, at the top, in 4 valves, 

 and containing very minute powdery granules and some larger grains. 



The genus consists but of a single species. 



1. Creeping Pillwort. Pilularia globulifera, Linn. 



(Fig. 1242.) 



(Eng. Bot. t. 521.) 



The slender rootstock often creeps to 

 a considerable extent, rooting at every 

 node. Leaves very fine, bright green, 

 usually 2 or 3 inches long. Capsules 

 like little pills, near 2 lines diameter, 

 and covered with short hairs. 



In the shallow edges of pools and 

 lakes, in temperate Europe and western 

 Asia ; not recorded either from the 

 Arctic or the Mediterranean regions. 

 Widely distributed over Britain, and in 

 some places not uncommon, but often 

 overlooked. Fr. summer and autumn.

III. CLUBMOSS. LYCOPODIUM. 



Perennials, with a branched, usually creeping stem, crowded with 

 small, moss-like, entire or minutely serrated leaves. Capsules sessile 

 either in the axils of the upper stem-leaves, or of bracts usually thinner 

 and broader than the stem-leaves, and forming an erect, cylindrical 

 terminal spike ; each capsule opening by a transverse slit in 2 valves, 

 and either all filled with minute powdery granules, or some contain- 

 ing larger grains. 



A large genus, widely spread over every part of the globe, and 

 readily divisible into two sections, often considered as genera, the true
