These two Piptadenias of South America have seemingly 
been given before their first specific designations, grata and obliqua, 
two names which have not already been used for species .in 
genus and which consequently are available for these plants. 
GoLpMANIA Rose ex Micheli, Mém. Soc. Phys. Genéve, xxxiv, 
274, t. 20 (1903). : 
Harms in Erginzungsheft ii. 148 (1906) of Die Natiirlichen 
Pflanzenfamilien has observed, in regard to the above genus, Rs 
ist mir sehr fraglich, ob sich die Gattung aufrecht erhalten 
sie diirfte vor allem mit Piptadenia Benth. sehr nahe verwandt 
sein. Ob das Vorhandensein eines diinnen Endosperms geniigt 
zur Abtrennung von Piptadenia, ist um so zweifelhafter, als 
Samenstruktur durchaus nicht aller Piptadenia-Arten bekann 
ist.” And Micheli, in publishing the genus for Rose, |. Co, Te 
marked that “ L’apparition générale de cette plante, la struct ' 
du fruit, ete., la rapprochent beaucoup du genre Piptadenia au 
nous Favions d’abord rattachée; mais l’observation de M. F 
d’aprés laquelle l’embryon est entouré d’une mince couche d’ 
sperme la rapprochent des Adénanthérées et spécialement du genre 
Prosopis dont V’éloigne d’ailleurs son fruit déhiscent.” 
I fail to see that any useful purpose is served by the segreg® 
of a genus upon a character so technical and difficult of observae 
tion as this when the plants concerned possess no other differences; 
and, as both Micheli and Harms indicate, the plants referred 10 
Goldmania are good Piptadenias in all save this one respect. 
worthy of note that a co-type specimen in the Gray 
G. constricta was originally determined by Micheli as @ new ® 
of Piptadenia. The reduction of Goldmania to Piptoilenit 
sitates the transfer of the following species.
