62 The Botanical Gazette. [February, 
Washington, Brandegee; Tulare co., California, Covz/le. The 
specimens distributed as Fimbriaria tenella in Canadian Hepat- 
ice no. 73 are of this species, at least in the sets in my her- 
barium and in the herbarium of Columbia College. 
8. Asterella echinella (Gottsche), nom. nov. 
Fimbriaria echinella Gottsche Mex. Leverm. 271. 1863. 
Orizaba, Mexico, Miller; Texas, C. Wright, 1849. Clearly 
marked by the prominent papille on the upper surface of 
the 9 receptacle. 
This includes all the species which I have seen from the 
limits of our flora. 
In Austin’s Hep: Bor.-Am. 236c, the habitat of the species 
included under that number (/imbriaria elegans) is given 
as ‘‘Texas and Cuba, Wright.” The specimens in my 
herbarium and those in the Gray herbarium are both accom- 
panied by fragments of a Se/aginella which to my knowledge 
does not occur in Texas. It is extremely probable that the 
specimens were collected in Cuba by Charles Wright, and 
that the reference to Texas was based on the specimens of 
the above named species which are in the Sullivant collection 
labeled ‘‘Fimébriaria elegans.” Now here we have a double et- 
ror, for neither Wright’s Texan specimens nor those distribu- 
ted in the Hep. Bor.-Am. belong to the species to which they 
have been referred. The former are clearly A. echinella, and 
the latter are described laterin this paper. This double error 
and the lack until recently of suitable material for comparison 
has made it impossible to co-ordinate our species from Mexico 
and the southwest. It is hoped that the present paper will — 
assist in straightening out the tangle. 
The genuine Asterella elegans has not to my knowledge 
been found within the limits of the United States but is to 
be looked for in the Sonoran region from western Texas to 
southern California as it is found on both sides of the conti- 
nent at a little lower latitude. We append a description 
that it may be recognized if found. Other Mexican and 
West Indian species follow. 
9. ASTERELLA ELEGANS (Spreng.) Trevis. Rend. R. Ist.
