longa. Carpella brevia, sessilia, plerumque elliptico-fusiformia, 
interdum breviora et ovaltielliptica, glaberrima, utroque latere 
costis 2-3 rectis acutiusculis percursa. 
Along the Kalamazoo River at Allegan, Michigan, 11 Sept., 
1902, collected by W. F. Wight. Two sections of a plant noted 
on the labels as ‘“‘5 feet high”’ are on U, S. Herb. sheets 430181 
and 430182. Being in good leaf and fruit at the date recorded 
indicates a plant flowering late in summer. It is of the T. pur- 
purascens group, and the leaflets are revolute. 
Thalictrum amabile nov. sp. 
Caulis verosimiliter metralis, striatus, glaber, pallide pur- 
purascens, foliis sat amplis, sessilibus usque ad medium paniculae 
lax instructus. Foliola firma, superne saturate viridia glaber- 
rimaque, inferne glauca et indumento biformi, nempe, e papillis 
minutis numerosissimis et globulis majoribus paucas crystallinis 
sessilibus conspersa, terminalia ambitu rotundata, 3 cm. diame- 
tientia, apiee leviter et latissime 3-lobata, lobis subaequalibus 
subtruncatis mucronatis. Rami. paniculae plantae .stamineae 
adscendentes, laxiflori. Flores mediocres albicantes. Sepala 4 
oblanceolata, acuta. Filamenta nec numerosa, nec valde elongata 
neque manifestim clavellata, pendula. Anthere pro affinitate 
plantae breves, lineari-oblongae, aristato-mucronatae, 
Only the staminate plant seen, and that in two specimens 
from near Mansfield, Ohio, collected in June, 1896, by E. Wilkin- 
son. On specimens showing so marked a habit, and so many 
characters of leaves and staminate flowers, there is little or no 
risk incurred in publishing a species on the one sex. The fine 
close papillose indument of the leaves beneath appears only under 
a very strong lens, but the sparse only subsessile larger transparent 
processes of the epidermis are visible with the simplest hand lens.
