A Revision of the Genus Clematis of the United States. 131 
chiefly a Florida form, and has been described under various names, 
and only lately restored as a variety. The species is quite a peculiar 
one, and not closely related to any other species. Loudon says it is 
_ found also in Japan,* but he has undoubtedly confounded it with some 
other species, which is, perhaps, similar. 
No. 11. C. lasiantha, Nuttall, is a strictly Californian species, being 
found in the southern portion of the State, about San Diego, thence 
north in the mountain valleys to Santa Barbara and the Napa Valley, 
and in the Sierra Nevadas to Plumas county. Nuttall says it is “allied 
to C. orientale, but very distinct.”+ According to Torrey,t Seeman 
refers it to UV. Peruviana, andif it is the same it would extend its dis- 
tribution greatly, to the southern hemisphere in fact, which is not the 
case with any of the other species of the genus in the United States. 
No. 12. C. paucifiora, Nuttall, is also a strictly Californian species, 
the only localities as far as I know being about San Diego, and in the val- 
leys of the Santa Ana mountains, not far from San Juan Capistrano, 
where I collected it myself. By some, it is considered to be a variety 
of lasiantha,§ and it seems to me to be also closely related to C. Drum- 
mondt. : 
No. 13. C. Drummondti, Torr. & Gr,, another western species, is 
found in the Pass of the Limpia, on Rio San Felipe and upper Colorado in 
Texas, at Cienega and Tucson in Arizona, probably south-east Califor- 
nia,|| and in Senora, Mexico. In Torrey and Gray’s Flora,@ this spe- 
cies is said to be nearly related to C. holosericea, and perhaps not 
specifically distinct, but it seems to me very antevent: 
No. 14. C. Virginiana, Linn., is the commonest and most widely dis- 
tributed of the corymbous white flowered species, in that respect resem- 
bling C. Viorna. The typical form is known from the mountains of 
northern Alabama, thence north to Virginia, and the following localities 
are given for it. District of Columbia, middle and northern counties 
of New Jersey, about New York (Pine Plains, and Long Island), 
Massachusetts, Buffalo, N. Y., Canada, Ohio, Indiana, Kentucky, 
Michigan (Ann Arbor), Wisconsin, Iowa (Davenport), Missouri 
(Vermillion river), Nebraska (Valley of Platte), Kansas, Arkansas, 
and Raton pass mountains near Santa Fe, New Mexico, and British 
America. If, as I have proposed, C. Catesbyana be classed under the
