2 SUPPLEMENT. 



[i.p. 3.] THALICTEUM. 



A Monograph of this genus by J. C. Lecoyer has lately appeared (Bull. Soc. Bot. Belg. 

 xxiv. 1885, pp. 78-324, tt. 1-5), and the author describes three proposed new species 

 from within our limits. Altogether he admits sixty-nine species, which he classifies in 

 two ranks according to their degree of distinctness, designating them primary and 

 secondary species. Out of the sixty-nine species retained by Lecoyer, thirty-three are 

 peculiar to Asia, five to Europe, one to Africa, and twenty to America. The Mexican 

 and Central-American species enumerated in this Monograph follow, the primary 

 species being preceded by a star : — 



*T. hernandezi, Tausch., T. lanatum, Lee, n. sp. (South Mexico), T. peltatum, DC. 

 (Costa Rica), *T. pubigerum, Benth., *T. longistylum, DC, *T. galeottii, Lee, n. sp. 

 (South Mexico), T. gibbosum, Lee, n. sp. (South Mexico), *T. wrightii, A. Gr., 

 T. fendleri, Engelm. 



Including his new species, Lecoyer records only nine, against our eleven, species. 

 On the evidence of collectors' numbers alone, he declares (loc. cit. p. 319) our T. stri- 

 gillosum to be a mixture of T. pubigerym and T. hernandezii. The former is a very 

 distinct species, of which we have examined the type specimen ; and as to the latter, of 

 which we have seen no authenticated specimens, if correctly described, it is quite 

 different from ours.
