AMERICAN CopE oF Botanical. NOMENCLATURE 173 
The publication of a new generic name as an avowed 
substitute for an earlier invalid one does not change the 
type of a genus. 
EXxAMPLES.— Psilogramme Kuhn, Festschr. 50-Jahr. Jub, Konigs. 
Realschule zu Berlin 332 (1882), is typified by the first-mentioned species 
of the second section Eupsilogramme, and not from species included in the 
first section _/amesonia, which is based on a generic name previously pub- 
hed; Phania DC. Prodr. 5: 114 (1826), is typified by P. mudlticaulis 
DC., the only species of the section Luphania ; Guignardia Viala 
& Ravaz, Bull. Soc. Myc. Fr. 8:63 (1892), which was substituted for 
h in Less. 
Syn, Compos. 203 (1832), is typified by Laestadia alnea (Fr.) Auers., 
which is the first of the three species given by Auerswald and accompanied 
by a citation of Fr. Scler. Suec. Exsic. 20. 59, and not by Laestadia Bid- 
wellii (Ellis) Viala & Ravaz, the only species mentioned by Viala & Ravaz 
at the time the substitution was made. 
(6) A figured species is to be selected rather than an unfig- 
ured species in the same work. In the absence of a 
figure, preference is to be given to the first species 
accompanied by the citation of a specimen in a regularly 
published series of exsiccatae. In the case of genera 
adopted from prebinomial authors (with or without change 
of name), a species figured by the author from whom the 
genus is adopted should be selected. 
Examp.es. — Lesfedeza Michx. Fl. Bor. Am. 2: 70 (1803), is typi- 
fied by ZL. procumbens Michx. loc. cit. pl. 39s the species first figured ; 
Stigmatea Fr. Sum. Veg. Scand. 421 (1849), is typified by S. Robertiana 
Fr., the fourth species, as there are no species figured and this is the first 
in the list accompanied by the citation of a specimen in published exsiccatae, 
Scler. Suec. Exsic. 0. 423. 
(c) The application to a genus of a former specific name of 
one of the included species, designates the type. 
EXAMPLES. — Amsonia Walt. Fl. Car. 98 (1788), is typified by 
Tabernaemontana Amsonia L., one of its two original species ; Sordaria 
Ces. & Comm. Soc. Critt. Ital. 1: 225 (1863), is typified by 
Sphaeria Sordaria ¥r., one of its twelve original species. 
Where economic or indigenous species are included in 
the same genus with foreign species, the type is to be 
selected from (1) the economic species or (2) those indi- 
genous from the standpoint of the original author of the 
genus. 
ExaMpLes. — Poa L. Sp. Pl. 67 (175 3), is typified by P. pratensis 
L., the first of the economic species ; Sanguisorba L, Sp. Pl. 116 (1753),
