This is evidently the commonest and most widely distributed species of 

 the genus extending from western Mexico to Tropical Brazil. It is 

 highly variable in stature, foliage, and degree of pubescence ; yet floral 

 or even vegetative characters for a satisfactory segregation appear to be 

 lacking. Var. glabra, Baker, in Mart. Fl. Bras. vi. pt. 3, 167, is, to 

 judge from its first mentioned type (Mandon's no. 80), merely a smoother 

 not an altogether glabrous form as its description would imply. 

 •H4- ■»-)- -w- Dwarf, not creeping, freely branched, smoothish : leaves, at least tlie 



upper ones, obovate or oblong, sessile by a narrowed but still somewhat 



clasping base : peduncles sliort or none. 



7. J. DiscoiDEA, Klatt, Arbeit, des Hamb. Botan. Mus. 1893, p. 2 

 of reprint. Heads small (not discoid even in Klatt's type specimen!), 

 short-peduncled or sessile : rays small although slightly exserted, white 

 or pale yellow. — Pringle, no. 4279 from the Sierra de las Cruces, State 

 of Mexico (type), also Pringle, no. 7349, Bonrgcau, no. 1232, and 

 Schaffner, no. 286, all collected in or near the Valley of Mexico. Per- 

 haps too near J. hirta. Klatt's ill-choseu name must be retained with 

 regret. 



++++++++ Low, creeping : leaves rounded at the base : Galapagos Islands.

Schultz's type) appears to me a mistalcen fidelity to an indefinite and inappropriate 

 specific name, especially when Dr. Rusby explains so carefully that he himself and 

 not Schultz should stand as authority for the pappus-bearing G. calva. Jaegeria 

 calva, as applied by Dr. Watson, was merely an herbarium name, resting upon an 

 obvious clerical error. Far from being "astonishing," slips of this sort appear to 

 be tolerably frequent in manuscript work of even the most careful botanists. The 

 thoughtless publication of such mistaken names, however, merely adds to tlie mass 

 of an already burdensome synonymy. It may be worth while to note in passing 

 that Dr. Rusby's name G. calva is not only inappropriate and misleading, but that 

 according to the Rochester Code it has no right to stand. G. calva, Sch. Bip., is 

 not, as Dr. Rusby maintains, a nomen nudum. It is clearly given (as Dr. Rusby 

 admits) by Baker in the Fl. Bras. vi. pt. 3, 167 (1884) in the synonymy of Jaegeria 

 hirta, var. glabra. Its status is thereby established, and it is impossible to deny its 

 publication, since it has been used in print together with a description, defining 

 synonymy, and the citation of Mandon's no. 80, one of the types originally men- 

 tioned by Schultz. But as thus defined it was applied to a Jaegeria. Whether we 

 write Golinsoga calva, Sch. Bip., or G. caira, Baker, in our synonymy of Jaegeria. 

 hirta, the combination Galinsoga calva has been a published binomial since 1884, 

 and Dr. Rusby's G. calva, applied to a different plant, is thus a later homonym 

 which a rational application of the Rochester rules would discard. It is to be 

 hoped that if any one feels impelled, on account of the "doctrine of homon^-ms," 

 to assign a new name to Dr. Rusby's species, the choice may be more felicitous.
