PENNELL: “‘ UNRECORDED’’ GENERA OF RAFINESQUE 91 
identifying Rafinesque’s species of Scrophulariaceae, if you know 
your species by other as well as by the traditional criteria, the 
task is not hopeless. Rafinesque had a sanguine, and sadly not 
unique, faith that all specimens (and likewise all descriptions) 
which seemed in any way ‘‘different’’ represented distinct species! 
Also his confidence in his own ‘‘natural”’ classification so often 
led him astray with respect to affinities that we are many times left 
blind. It is a tragedy that Rafinesque’s herbarium has not sur- 
vived. 
As a first step toward an appraisal of Rafinesque, I should 
like to have collected the species unrecorded in the Index Kewensis, 
but such a list with comments would be too long for presentment in 
this journal. More importance attaches to the knowledge that 
unused generic names exist. This paper is the first of several in 
which I shall attempt to record briefly the unrecorded genera of 
Rafinesque, upon what they are based, and whether the names 
are available for use. No responsibility is assumed for the iden- 
tification of any of these and the describer’s own statement of 
their affinity is given for the purpose of enabling any worker to 
know if a certain genus is, or is not, of the group of his own special 
interest. 
The Autikon Botanikon doubtless contains the majority of 
Rafinesque’s unrecorded names, inasmuch as it is his only large 
work overlooked. In it all the new genera are described so that 
the validity of their publication must be recognized by all. Con- 
sequently it is important to have these presented. The following 
list retains the numbers of Rafinesque’s series, while for those 
who may cite these genera from my list I include in parentheses 
the pages of the original. 
15. Junta Raf. (p. 6). Type species, J. triflora Raf. ‘Received from Florida, 
but pete serene ecoaan or African I am not sure.’’ Said to be near Clethra 
and Cyr dated a Junia Adans., 1763. 
33. Ronconia Raf. (p. 9). pe species, R. siete Raf. ‘‘(Ammania auri- 
culata nonullis). . . . Egypt.” Feb from Amm 
60. IonpRA Raf. (p. 11). Type species, Thlaspi arabica “L., "actually (L.) 
Vahl, Symb. Bot. 2: 76. 1791, based upon Iberis arabica L., Cent. Pl., 1:17. 1755. 
Tondra arabica (L.) Raf. This is considered to be a species of Aethionema R. Br., 
$8Is. 
63. CaRGILA Raf. (p. 11). Type species, C. dichotoma Raf. ‘South America.”
