Caule alato ramofiffimo, foliis lineari-lanceolatis integer- 
rimis coftà proliferis. 
The frons is membranaceous, extremely thin, bright red, about 
two or three inches high ; divided immediately from the root into 
numerous branches, growing without order, and winged on each 
fide with a thin membrane. The leaves are linear-lanceolate, 
very entire, feffile or on very {hòrt footftalks, growing without order, 
and arifing from the nerve, which runs through every part of the 
frons : from the nerves of thefe leaves arife others proliferous, from 
two to fix on each leaf, and from thefe again others ftill {maller ; 
the extreme ones lanceolate. _ ; 
The fructification appears to be dicecious—The male confifting 
of veficles, the fize of the feeds of muftard, of. a. much deeper red 
colour than the frons, fituatéd on the nerve near the extremity of 
the leaves— Female, numerous very minute grains fcattered near 
the nerve on each fide of the leaf. > 
Such is the appearance, if. we are to conhaer the fru&ification 
of thefe plants as dicecious; but as this is a matter of great doubt, 
it is pofhble thefe different appearances may be accounted for 
by fuppofing that the red veficles are real capfules replete with 
feeds; and that the granular appearance proceeds from the cap- 
fules having burít, and difcharged their feeds, which adhere to 
the furface of the frons, until that decaying, they are depofited in 
the place proper for their vegetation. Upon this fuppofition, the 
capfules are of courfe deciduous, and difappear uke the feed-veffels _ 
of other known plants. 
This fpecies may be placed in the Syftema Vegetabilium next 
to Fucus alatus in Mr. Hudfon’s third fubdivifion, Alati, f. fronde 
plane, ftipite medium folium percurrente,
