Psoralea pentaphylla

"Habitat in Mexico vel Malabaria." RCN: 5633.
Lectotype
(Grimes in
Mem. New York Bot. Gard.
61: 82. 1990): [icon] "
Psoralea pentaphylla
, radice crassa
" in Jussieu in
Mem
. Acad. Roy. Sci.
Paris
1744: 381, t. 17. 1744.
Current name:
Pediomelum pentaphyllum
(L.) Rydb.
(
Fabaceae
:
Faboideae
).
Note:
Ockenden (in
S. W. Naturalist
10: 122. 1965) argued that the traditional usage (i.e.
sensu
Rydberg) of the Linnaean name did not match the Jussieu plate, which he could not identify with certainty, and so published the new name
Psoralea palmeri
Ockenden
for
P. pentaphylla sensu
Rydberg
non L. Later, Grimes (in
Mem. New York Bot. Gard.
61: 82-83. 1990) stated "Typus, in default of a specimen, the protologue. The illustration in the protologue [i.e.
Jussieu's
description and illustration] is ambiguous, resembling either this taxon, or
Pediomelum hypogaeum
var.
subulatum
. In combination with the description, however, the identity is decisive". This is accepted as effective lectotypification on the Jussieu illustration. Grimes erroneously used the name
Pediomelum pentaphyllum
(L.) Grimes
for the taxon agreeing with the type of
Psoralea pentaphylla
L.
, but not the description of
Pediomelum pentaphyllum
(L.) Rydberg. This
error was later pointed out by Kartesz & Gandhi (in
Phytologia
72: 86-87. 1992).
