present no reason, according to the International Rules, to reject — 
E. glandulosum HBK., a name which was amply characterized and 
put forward in all good faith. The plant of von Jelski, however, pos- 
sesses a round-ovate instead of triangular-ovate leaf, and the indumen- 
tum, which Hieronymus finds similar, appears to the writer very differ- 
ent. In EF. glandulosum the hairs are short, dense, and gland-tipped, 
in the von Jelski plant on the other hand they are flaccid, slender, 
jointed, and for the most part not gland-tipped. From the sterile 
fragment, kindly supplied to the writer at the Royal Gardens in Berlin 
during his visit in 1905, it would appear that the plant is certainly 
distinct from the Mexican £. glandulosum HBK. (£. adenophorum 
Spreng.), but until fertile specimens are available it is quite impos- 
sible to give the plant definite disposition. 
E. aromaticum L., a species of Atlantic North America, extending 
from Massachusetts to Florida, was recorded as also from Peru by 
Lamarck, Encyec. ii. 406 (1786), on the basis of a specimen from Joseph 
de Jussieu. The plant was stated to be smaller than the North Ameri- 
can and to have shorter petioles as well as other minor differences. 
Just what species Lamarck thus identified has not been ascertained, 
but there is no likelihood of its having been conspecific with the 
North American plant. oat 
- E. cannasinun L,, the well-known European species, and the medic- 
inal E. rRIPLINERVE Vahl (under the later name of E. Ayapana Vent.) 
were reported by Martinet, Enum. Jard. Med. Lima, 352 (1878), = 
cultivated in the Botanic Garden of the Medical Faculty at Lima; 
but there is little likelihood and certainly no Boe that either 
has at any time escaped or become established in Peru. : 
E. pre eat 3 Encye. ii. 408 (1786); Robinson, Proc. Am. 
Acad. liv. 349 (1918). Described from a specimen in the P oe 
herbarium of Joseph de Jussieu, this species has been traditi y 
attributed to that country, though all its subsequent collections appe? 
to have been in northern-central Ecuador. It is to be sag ie ded 
that the boundaries of Peru in the middle of the 18th Century care

in what is now Bolivia, but the fact that he was also in the
