RENNERT: THE PHYLLODES OF OXYPOLIS FILIFORMIS 411 
structure of the septa as examined by myself differs notably from 
that described by Briquet. 
2. The phyllodes normally bear numerous glands sunk in pits 
which are edged with a minut. scale. These glands are on a line 
at 90° from the plane of the stipules and the attendant scales may 
not be considered as vestigial leaflet structures as suggested by 
Goebel as to the scales of Crantzia. 
3. Plants of Oxypolts filiformis when grown in a saturated at- 
mosphere or under the influence of normal soil-water (submerged) 
exhibits marked hydrophytic adaptations of the phyllode. The 
changes ensuing under such circumstances emphasize stili further 
the xerophytic character of the phyllodes as indicated by their 
anatomical character, and reénforce the conclusion that this species 
should be regarded as a swamp xerophyte.
