The Anatomy of Nephrolepis volubilis J.Sm. 259 
more or less constant: the diagrams illustrate the different ways in 
which this object is attained. 
Text-fig. 5. N. volubilis. Serial sections through basal part of 
lateral plant, a-h are from one plant, b' and d! from another to show the 
varying relative positions of the stolon- and leaf-strands. S, S 2 , first and 
second stolons ; D, D 2 , dorsal strands of first and second leaves, respectively. 
Xylem shaded, endodermis shown as a broken line. 
3. The internal structure of the Lateral Plants in Nephrolepis , 
except for Trecul’s 1 short account of his unnamed plant, remains 
undescribed. A comparison of the lateral plant in N. cordifolia 
with Chandler’s* description of the “ sporeling ” of that species 
revealed certain differences which will be noted below (p. 263). It 
is unfortunate that for N. volubilis such a comparison is impossible 
till plants raised from spores are available, but a description of the 
lateral plant may be given.
