CATALOGUE OF SPECIES. 
RANUNCULACES. 
Clematis scottii Porter; Port. & Coult. Fl. Col. 1 (1874). 
The specimens in this collection are like those collected by Dr. Scoville in Colo- 
rado, but not like those obtained by Lemmon in Arizona, which undoubtedly belong 
toadistinct species. Coulter, in the Manual of the Rocky Mountain Region, describes 
the sepals as less hairy than those of C. douglasii. In mine they are fully as hairy, 
but thicker and shorter. 
On hillsides near Hot Springs, altitude 1,060 m., June 1,17; in fruit, August 2 (No. 
481). 
Clematis ligusticifolia Nutt.; Torr. & Gray, Fl. i, 9 (1838). 
In canyons among the foothills: Hot Springs, altitude 1,050 m., August 2 (No. 482). 
A form with large (5 to 7 em. long) and dullish leatlets and very long (15 to 22 em.) 
and slender peduncles, was collected on the very steep sides of Hot Springs Canyon, 
near the Chautauqua grounds, altitude 1,050 m., August 3 (No. 483). 
Clematis alpina tenuiloba (Gray). 
Gray ‘ makes this a subvariety of C, alpina occidentalis Gray, which is described as 
having smooth achenes. In my specimens they are silky. The plant further differs 
from C. alpina ochotensis or occidentalis in having more delicate stems, smaller and 
more lobed leaves with more rounded lobes and sinuses, and longer, lanceolate sepals. 
This plant has been collected also by Dr. Chas, KE, Bessey at Manitou, Colo. It was 
sold in albums of Black Hills flowers at Deadwood under the name of C, douglasii. 
Perhaps the silkiness of the achenes was the cause of this error. 
Here and there in canyons, in the Black Hills proper, near Piedmont, altitude 1,200 
m., June 27; Lead City, altitude 1,600 m., July 6; Bull Springs, in the Limestone 
District west of Custer, altitude 1,900 m., July 27 (No. 484). 
Pulsatilla hirsutissima (Pursh) Britton, Ann. N. Y. Acad. vi, 217 (1891); Clematis 
hirsutissima Pursh, Fl. i, 3885 (1814). 
Common in the Hills: Custer, altitude 1,650 m., May 28, 31, June 4 (No. 485). 
Anemone multifida Poir. inecyl. Suppl. i, 364 (1810). 
Not uncommon in the Northern Hills: Elk Canyon, altitude 1,200 m., June 29; Lead 
City, altitude 1,800 1m., July 4; Rochford, altitude 1,700 n., July 11 (No. 486). 
Anemone cylindrica Gray, Ann. Lyc. N. Y. iii, 221 (1836). 
In the Northern Hills: Hermosa, altitude 1,000 m., June 21; Lead City, altitude 
1,700 m., July 6; Rochford, altitude 1,650 m., July 11 (No. 487). Several of the plants 
have some of the peduncles with secondary involucres. In a few specimens from 
Elk Canyon, altitude 1,200 m., June 29, the divisions are also broad, and the plants 
can not be distinguished from A, virginiana, except by the very short style (No, 488). 
Thalictrum purpurascens L. Sp. PI. i, 546 (1753). 
In canyons, among the foothills: Hot Springs, altitude 1,050 m., June 18; Elk 
Canyon, altitude 1,200 m., June 29 (No. 489). 
Thalictrum occidentale Gray, Proc. Amer, Acad. viii, 372 (1872). 
The specimens are rather too young for identification. None were seen in fruit, as 
I was not in the locality of the plant except in the early part of the summer. The 
foliage is very like that of 7. occidentale, and the plant agrees well with the descrip- 
tion of that species. If the determination is correct, the range of 7. occidentale is 
extended far east. 
Elk Canyon, altitude 1,200 m., June 29 (No. 490). 
Thalictrum venulosum Trelease, Proc. Bost. Soc. Nat. Hist. xxiii, 302 (1886). 
This is 7. dioicum L., of Newton & Jenney’s Report.? 
The only specimens in fruit seem to be typical. They were collected near Bull 
‘In Newton & Jenney, Geol. Surv. Black Hills, 531 (1880). 2 Loe. cit., p. 532,
