Trautvetteria Ranunculaceae r 465 



2545. TRAUTVETTERIA F. & M. 



1. Trautvetteria carolinensis (Walt.) Vail. False Bugbane. Map 956. 

 This species was reported from the "knobs" on the authority of Clapp in 

 the "Catalogue of Plants of Indiana" published in 1881. This report was 

 repeated in Coulter's Catalogue to which was added a report for Barnes 

 from Clark County. Dr. Clapp was an industrious and, I think, a very 

 accurate botanist. He came to Indiana about 1817 and continued his 

 botanical work until his death in about 1865. I was fortunate in being able 

 to purchase his copy of Gray's Manual, first edition, and an interleaved 

 copy of Riddell's "Flora of the Western States" in which he kept a list of 

 the plants he collected in the vicinity of New Albany. In the Riddell's 

 Flora he had bound 48 blank pages, on which he kept records. When he 

 found a species in Indiana, he indicated it by a check mark in the cata- 

 logue. On one of the blank pages he summarized his work up to the end 

 of 1840 and he recorded a total of 918 plants, which included 25 ferns. 

 His last note was made in 1857 and whether he failed to keep records 

 after that date I do not know. Nowhere in his books, however, does he 

 mention collecting this plant under the name Trautvetteria or any of its 

 synonyms. There is a specimen in the herbarium of Purdue University 

 which is from the herbarium of C. R. Barnes and the label states that 

 it was collected by A. Clapp, 1837, near New Albany, Indiana (Floyd 

 County) . There is another specimen collected in 1837 by Dr. Clapp in the 

 herbarium of Wabash College. These specimens were, without doubt, the 

 basis for the Floyd County report for Clapp in Coulter's Catalogue. The 

 fact that the first specimen was in the Barnes herbarium probably led 

 to the report of his collecting it in Clark County, where most of Barnes' 

 collecting was done. There is not now a specimen in the Purdue herbarium 

 which was collected by Barnes in Clark County, nor does Barnes men- 

 tion this species in any of his writings. There is a specimen in the 

 herbarium of DePauw University collected by Blatchley which was in 

 bud June 8, 1889, and was collected in the Heckland prairie about 10 

 miles northeast of Terre Haute, Vigo County, and one in the Gray Her- 

 barium bearing the following label: "Low prairies, w. Ind. E. F. Shipman, 

 1876."

2546. RANUNCULUS [Tourn.] L. Buttercup 



The status of some of the species of this genus has been variously 

 interpreted. The species have been divided, and the names have been 

 changed since publication of the fifth edition of Gray's Manual and of 

 Wood's Class-book of Botany (1885). Since these books were used by 

 our early botanists, it is not satisfactory to accept the early reports of 

 the species of this genus. 



Plants aquatic; leaves finely dissected; achenes wrinkled. 

 Flowers yellow. 



Leaves of submerged plants sessile or on petioles less than 1 cm long, the seg- 

 ments acute; leaves of emersed plants on petioles mostly 1-3 cm long; achenes
