RANUNCULACE, 
CLEMATIS sertatcatiea Nutt. in Torr, & Gray, Fl. 1, p. 9. Near San Antonita, New Mexico ; 
October. In fru 
(CLEMATIS ame (sp. nov.): humilis? herbacea? glabella ; foliis pinnatis vel subbipin- 
- natis; foliolis 7-9 trilobis tripartitisve longiuscule petiolulatis, lobis subovatis integerrimis nunc 
incisis ; pedunculis solitariis unifloris; calyce subeampanulato, sepalis anguste oblongis haud 
crassis apice obtuso patentibus ; caudis caxpolloram dense plumosus. On the Sandia mountains, 
New Mexico; October. Ofthis apparently new Clematis there is only a single flowering specimen 
and a few mature carpels in the collection. The stem appears to be low and nearly herbaceous, 
but it probably elongates and climbs by the petioles. The leaflets are only from half an inch 
to an inch in length, membranaceous and inconspicuously veined ; those of the lower pinnz more 
divided. Peduncle an inch or two in length, nodding in flower. Sepals scarcely over half an 
inch in length, pale, membranaceous in the dried state, probably a little thickened in the living 
plant, but not leathery as in C. Viorna, C. Pitcheri, etc., almost glabrous, except the densely 
tomentose margin, not appendaged, but the obtuse tip spreading. Carpels silky pubescent, 
becoming glabrate ; the tails over an inch long, plumose as in C. Viorna. The flowers are_ 
smaller than in any other North American species of this division. 
TIS LASIANTHA. Nutt. in Torr. & Gray, Fl. 1,p.9. Hill sides, Napa valley, April 27. 
Only the male plant of this showy species was collected by Dr. Bigelow. The female was not 
known when the Flora of North America was published ; but it has since been found by Colonel 
Frémont. The carpels have tails of about an inch and a half in length. 
Tuaticrrum Fenpiert, Engelm. in Gray, Pl. Fendl. p. 53; var.? potycarpum: glaberrimum ; 
carpellis numerosioribus eglandulosis. Mountain ravines, New Mexico, In fruit October, &c. 
Sides of rivulets, Napa valley, California, April 25, (withimmature fruit). It occurs in Coulter’s 
California collection, in flower only. Leaves mostly petiolate, ternately decompound : leaflets 
obovate and cuneate, incisely 3-lobed ; the lobes cut or entire. Panicle contracted, few-flowered. 
Sepals ovate, rather acute. Carpels 15-25, ovate, compressed, with two prominent ribs on each 
side. Stipoan linear, elongated. T. Fendleri has a more compound and spreading panicle than 
our plant, and the carpels are more or less glandular. 
THALIcTRUM Dioicum, Linn.; Torr. & Gray, Fl. 1, p. 38. Mountains near San Gabriel ; 
March 23. Only the siete Powers are in the nillectioney and it is possible the plant may be 
distinct from T. dioicum. That species occurs in Oregon :
