1 14 Worsdell . — On the Comparative Anatomy of 
C. subaeaulis, Gardn. 
This plant is much more reduced than either of the two 
other species investigated. It is parasitic on the roots of 
the Bamboo , amongst the thick, tangled masses of which 
its own roots vegetate in a mutually anastomosing network. 
The subaerial part is extremely mucilaginous, much more 
so than either of the other species ; at the end of the season 
this character becomes more marked, till the whole becomes 
resolved into a decaying, mucilaginous mass. A purple 
substance occurs throughout the entire plant, especially in 
those parts active in secreting a ferment. 
The general morphology of this plant is similar to that 
of C. bicolor , Gardn., so that I may at once proceed to describe 
the anatomy. 
Anatomy of the Root. 
As seen in a transverse section, the external layer of the 
cortex consists of small cells, usually with conspicuous nuclei, 
and thick brown walls, both on the inner and outer sides. 
The main cortical tissue consists, especially in its inner 
portion, of large, rounded cells, containing, usually, very 
numerous compound starch-grains. Owing to the loose 
arrangement of these cortical cells, there is a conspicuous 
intercellular system ; in the spaces thus formed a fungus 
occurs ; it is constantly present, as shown by its reappearance 
in every root or portion of root examined. The exterior 
surface of the cell-walls are lined with its hyphae, from which 
conidia-like bodies jut out into the space ; these arise from an 
excessively short stalk, from which two, three, or a larger 
number of conidia are abstricted off (Fig. 26) ; these fall on 
the wall of the cells (Fig. 27). But, besides these smaller 
bodies thus formed in such numbers, there may be observed 
larger, spore-like bodies, of a dark brown colour ; these 
appear each on the end of a stalk and inclined to one side 
of it, that portion of the stalk immediately below it appearing 
rather swollen. At more advanced stages two of these
