stem; midrib distinct, vanishing below the apex of the leaf; 
leaves of the upper plane ovate, abruptly short acuminate, densely 
Serrate-ciliate and provided with a conspicuous white margin, 
slightly oblique and mostly closely imbricate; spikes scarcely 
quadrangular, short, lax, with ovate-lanceolate bracts which are 
ciliate with a narrow pellucid margin.

Allied to S. Schiedeana A. Br., but differs in the conspicuous 
white margins of the leaves of the upper plane. Four or occa- 
sionally three rows of cells enter into this pellucid margin, and as 
in the above named species each bears a small tubercle. It differs 
further in the shorter and thicker terminal mucro and in the char- 
acter and abundance of the tooth-like cilia. In S. Schiedeana : 
these are scattered, long and slender, and stand at right angles to 
the leaf-margin ; in S. rveflexa they are two or three times as nu- 
merous and stand like serrations for the most part, each one short 
and pointing forwards. In S. reflexa the fruiting spike is shorter 
and more lax, and the leaves of the lower plane are strongly re- 
curved, leaving the white-margined upper leaves lying like over- 
lapping Scales across the upper surface of the cord-like stem. 
Botanical Notes, 
: Pistillodia of Podophyllum stamen. Among cultivated plants 
. is not unusual to find instances of stamens taking on the form 
if not the function. of pistils, the most striking examples being 
Perhaps found among the poppies and lilies. With wild plants 
any such tendency is less frequent and it may be interesting to 
Note that a student, while at class-work examining the flowers of 
the common mandrake (Podophyllum peltatum), called my atten- 
ton to a peculiar floral structure which proved to be a stamen 
with the upper portion of the anther bearing a stigma of the 
“orrugate form common to the Podophyllum pistil, while below 
the Stamen was of the normal form.
