Locur1.—The peripheral 
series of loculi which run 
longitudinally and somewhat 
spirally are more numerous 
than the loculi of Telangium 
Scottii, numbering in the 
middle zone of the sporange 
twelve (figs. 3, 9; cf. also 
text fig. 4). Their approxi- 
mation into groups is some- 
times seen near the apex 
(CN .383.10). Immersed in 
the ground tissue of the cen- 
tral region of the sporange, 
except at the extreme apex, 
there are further loculi, of 
which at least four appear 
in transverse sections (figs. 3, 
12). Text fig. 3 is drawn 
from longitudinal sections 
too near the periphery to 
give the number and disposi- 
tion of central loculi. The 
origin of additional central 
loculi by segmentation of 
peripheral loculi is suggested 
in some cases (text fig. 4), 
and the presence of ripe 
spores almost uniformly dis- 
tributed in figs. 11 and 12 
(CN .307.17, 18) suggests 
that the main content of the 
young normal sporange was potential sporogenous tissue. Each 
loculus is surrounded by a sheath of small, longitudinally ex-
