An evergreen, somewhat suffrutescent plant; the long, 

 slender, subterranean runners have long internodes and bear 

 scale-leaves. Fig. 38 Л shews a runner like the one in ques- 

 tion; it is there shewn as having risen above the ground in a 

 curve and having formed a vertical aerial shoot (/) with two 

 foliage-leaves (/",/"), which has died down to the ground; but 

 from its base a new shoot {II] has been given off which

A, A rhizome teiminating in 1, in a dead inflorescence and two decayed foliaije-leaves (/,/): 

 //, A lateral shoot bearing 3 foliage-leaves. B, A subterranean runner Avith branch; of 

 the two shoots the lower one is below the surface of the soil, and the upper one has 

 risen above the ground and bears a large terminal bud {g). C, A vertical rhizome term- 

 inating in a (dead) inflorescence ; /, a foliage-leaf. Two pale lateral shoots bearing scale- 

 leaves rise straight into the air and are somewhat abnormally lengthened owing to the 

 fact that the plant has been overgrown by moss. D, The apex of a runner of P. secunda.

bears three foliage-leaves and terminates in a bud protected 

 by scale-leaves. In Fig. 38 Б a similar runner is shewn which 

 has risen above the ground (bearing the terminal bud, g] 

 and has given off a branch at a. The runners are curved 

 like a hook at the apex (Fig. 39 B. 0, E). Their roots spring 

 from the axils of the scale-leaves, above the axillary buds 

 (Fig. 39 A, B, D, F), and are very slender and sparingly
