Mulil, Cat. PI. Am. Sept. No. 8, in Herb. Willd.
1-3 ! (1813). — I am not aware that Muhlenberg published
any description of it ; if he did so before 1814, his name will
take precedence. P. exstipulatus Bonpland MS. is P. cmgustifoliiis
H. B. K. Nov. Gen, et Sp. i. 370, and is to be referred to P.
pectlwitm (aggregate). It is contained in Herb. Willdenow at
Berlin, No. 3206, f. 4, 5.
P. MExicANus Ar. Benn. Journ. Bot. 1887, 289. — This was
named P. peruviana by Presl (ined.) in Herb. Prague !
P. ANGusTiFOLius Presl.—The date of this is 1821, as I supposed
(Journ. Bot. 1889, 263): fascicles 1-10 of tlie ' Rostlin' were published
in that year ; Roth's name P. Zizii (1827) is thus antedated
by six years.
P. RUFEscENS Schrad. — In writing of this (Journ. Bot. 1889,
243) I
and ii.
expressed an opinion that Roth's serratus (Fl. Gerin. i. 73,
205 (1788-1800) ) from his reference to the plate m Fl.
Danica must be liicens, but he also refers under lucens to the same
plate, so it must have been a slip ; and the serratus of the Beitrage
(ii. 126, 1783) most certainly, from the description, applies to
ru/esec7ts.
P. Wrightii Morong, Bull. Tor. Bot. Soc. (1886) xiii. 158, t. 59.
P. viucronatus Presl, Epimelife BotanicfB, p. 245 (1849), non auct.
—This is No. 1381 of Cuming's plants from the Philippine Islands.
There is no doubt Morong's name is preoccupied by P. malaina
Miquel, 111. Fl. Arch. Ind. p. 46 (1871). A very poor and imperfect
specimen, communicated by Dr. Buchenau from Kashmir, W. Himalaya,
alt. 5800 ft. (Schlagintweit, 9 Cat. No. 10449), I beheve to be
the same, though there is neither flowers or fruit. It is named
jUdtans, which it is not. The fruit of P. Wn'f/htH is very distinct
and characteristic.
P. LiEBMANNi Buchenau, Nat. Ver. Bremen, iii. 349 (1873).
An authentic specimen of this plant, gathered by Liebman, and
communicated by Dr. Buchenau, is Schollera (jraudnea Willd. =
Hetei-anthera (/raiiiinea Vahl. ; so it would seem that this Mexican
plant must be excluded from the genus.
P. jAVANicus Hassk. — In this Journal for 1887, p. 177, I expressed
an opinion that this might be ditferent from P. tennicaulis
Mueller ;
but Dr. Schinz, of Zurich, who possesses a type specimen
o^ j'tvanieiis, assures me they are the same species; the P.purvifoHa
Buch. must also certainly be referred to javaidcus. The synonymy
will be
