294. CHARACEJE INDIZ ORIENTALIS 
plants. It possesses an articulated stem, with whorls, each of ten 
leaves, which are very narrowly spathulate, in the upper part deeply 
pinnatifid with three pairs of linear segments, of which the inferior ones 
are the longer, and sometimes once more divided in the outside. As 
there are no flowers I am unable to come to a more accurate determi- 
nation of this plant. In several other collections I have found, under 
the name of Ch. furcata, specimens of Ch. corallina, distributed by 
Hornemann. 
3. N. (exilis var. ?) flagelliformis, monoica ; tenuis, flexilis et pellucida ; 
verticillis omnibus laxis e foliis 5—6 duplicato- vel in radiis nonnullis 
triplicato-divisis, articulo primario valde elongato, segmentis divisi- 
onum insequentium sensim brevioribus, ultimis mucrone imposito 
angusto acuto apiculatis ; seminibus solitariis oblongis, coronula 
brevi, nucleo acutangulo, fasciis 9—8. 
T haye seen of this species only some fragments adhering accidentally 
to Chara corallina, communicated by Hornemann under the name of 
Ch. furcata. Tt resembles most nearly N. gracilis (Ch. gracilis, Smith) 
and N. exilis (Ch. exilis, Amici, Ch. flabellata, Reichend.), according 
with the latter in the size of the seeds, but differing somewhat by the 
greater elongation of the first joint of the leaves, and by seeds with 
still sharper angles on the nut. Length of the nut 35:3! m. 
4. N. byssoides, monoica, minima, flexilis et pellucida, dense et intri- 
catim cæspitosa ; verticillis densioribus e foliis 6 breviusculis, medio 
divisis, uno alterove radio iterum diviso, segmentis ultimis mucrone 
imposito minutissimo acuto apiculatis ; seminibus solitariis subglo- 
bosis, coronula brevi obtusa nuclei gyris non prominulis, fasciis 6—7. 
On the coast of Coromandel, collected by Bellanger (1826-28). 
This species requires future researches to ascertain whether it must 
be left as such, or united with W. tenuissima, as the smallest variety of 
it. It differs, however, by its exceedingly minute size, its leaves only 
twice divided, its whorls less compact, and still smaller seeds, The 
yellow-brown nut of the seed is only 412, m. long.
