Palmer’s No. 176 was identified by S. Watson with A. palmati- 
fida.* According to Palmer, the plant is known by the vernacular 
name “‘Sayas”’ and the roots, which have the taste of the 
parsnip and carrot, are eaten by the Yaqui Indians, and made 
into a preserve by the Mexicans. 
According to Havard (l.c.) the roots of A. palmatifida when 
roasted have the taste of the parsnip and carrot, and are eaten 
by the Papago and Pimo Indians as well as by the Mexicans 
under the name of “ Sayas.’

VERA Cruz. On the way from the town of Vera Cruz to 
Jalapa, between Manantial and Paso de Ovejas, fl. Aug., Schiede 
(co-type in Mus. Brit 
Planchon cannot ie quoted as the authority for the combina- 
tion A. Schiedeana, inasmuch as the plant which he described - 
and figured under that name belongs to a different species, 
A. colombiana, and the only other specimen seen by him (Coulter 
789) is referable to a third species, A. palmatifida. Nor can 
Asa Gray be cited as the authority, since the two species which 
he identified with Huryanthe Schiedeana were A. Wrightii and 
A. palmatifida. The name A. Schiedeana, Planch. is therefore 
treated as a ‘‘nomen delendum”’ and the combination A. Schie- 
deana is made de novo.t

It differs an all the other known species by its anthers, which 
dehisce by means of a single pore instead of by two. If it is 
really an Amoreuxia, we have an — case of parallelism 
between this genus and Cochlospermum : Cochlospermum subgen 
Eucochlospermum Planch.{ has anthers which dehisce by a single 
pore; whereas in subgen. Diporandra, Planch.§ the anthers open 
by two pores.
