10. Thalictrum strigillosum, Hemsley, Diag. Pl. Nov. pars 1, p. 1. 
Caule ramisque plus minusve strigillosis, foliolis graciliter petiolulatis subtus hispidis supra sparse 
puberulis, floribus longe pedicellatis, antheris insigniter aristatis, stylo pubescente longissime 
exserto, acheeniis fere sessilibus rugis elevatis reticulatis notatis. _ 
Herba 2-3-pedalis, ramosa, strigilloso-hispida. Radix subcarnosa, fibrosa. Caulis sulcato-striatus, 
. strigillosus vel demum fere glaber. Folia (radicalia non vidi) petiolata, subquadri-ternatim 
divisa, foliolis petiolulatis, cordato-rotundatis vel basi cuneatis, apice 3-5-lobatis, ad 8-12 
lineas latis, pracipue subtus secus nervos hispidis. Flores longe pedicellati, pedicellis basi 
bracteis parvis munitis ; sepala glabra, ovato-oblonga, ad 3 lin. longa; stamina calycem supe- 
rantia, filamentis capillaceis, antheris aristatis filamentis equilongis. Achenia circiter 7, 
sessilia vel brevissime stipitata, oblique lunata, 2-3 lin. longa, insigniter costato-reticulata. 
SoutH Mexico, rare in ravines among bushes (Schaffner), Tizapan, valley of Mexico 
(Bourgeau, 276), Zimapan (Coulter, 652), mountains around Mitla, Oaxaca (Andrieus, 
546), between San Miguel and La Joya (Schiede). Hb. Kew. 
This differs from its allies 7. rutidocarpum, longistylum, &c. in being more or less 
clothed with hispid hairs, which on the stem are long and on the leaves short, and in 
the leaflets, anthers, and achenes. Perhaps it will eventually be found necessary to 
unite several of these forms as one variable species.
