hypodermate pallido lineatis, margine utroque a dentibus plurimis

The subrobust stems are nearly 1 line in diameter and bear 
the leaves in whorls of 3-5, the lower internodes being about 
3 in. long, but becoming much shorter above, the upper part of 
the shoot being densely leafy. The leaves are about 10 lines 
long, scarcely 1 line broad at the base, whence they taper 
slightly to the rounded tip; each margin bears about 100 rather 
close-set spiny tooth-cells projecting upwards from the small- 
celled epidermis, beneath which is a hypoderma consisting of 
two rows of narrow elongated, almost colourless, regular cells ; 
there is a pair of delicate colourless triangular-subulate intra- 
foliar stipules, each half a line long. No male flowers were 
present. The female spathes are large, being 2} lines long by 
+ line broad, bifid for nearly 3 their length, and minutely 
spinulose on the free margins, with a few pairs of small spiny 
teeth on the lateral sutures. Each spathe bears a developed 
flower, and also encloses at the base an unopened female bud, so 
that it is potentially 2-flowered. The pyriform unicellular ovary 
contains 5 long-stalked orthotropous ovules. 
Resembles in appearance the common Hydrilla verticillata, 
Presl, owing to the whorled leaf-arrangement, in which it differs 
from all other species of Lagarosiphon, though a tendency to this 
arrangement is observed in LZ. rubella, Ridl. 
In the bifid stigmas and erect ovules it conforms to Lagaro- 
siphon, these being respectively entire and anatropous in Hi ydrilla. 
In both genera the female spathes are described as one-flowered, 
but in the present species a small unopened bud is found by the 
side of the ovary of the developed flower.
