CopDE OF BOTANICAL NOMENCLATURE 
(c) The types of genera adopted through citations of nonbi- 
nomial literature (with or without change of name), are to 
be selected from those of the original species which 
receive names in the first binomial publication. The 
genera of Linnaeus’ Species Plantarum (1753) are to be 
typified through the citations given in his Genera Plan- 
tarum (1754). 
Notre.—The Species Plantarum contains no generic references, but 
the 1754 edition of the Genera Plantarum was evidently prepared at the 
same ee = was in — a yen sereraeed volume of the same work. It 
than other editions with the treatment followed in 
the Species Plantarum, and thus makes it possible to retain more of the 
Linnaean a names in their current application. 
Ex ES.—Cypripedium L. Sp. Pl. 951, 2 genus adopted from 
refort with a change of his name Ca/cco/us, is typified by Fae gt 
Catccutis, the only species common to both authors; Sese/i L. Sp. 
a genus adopted from B oerhaave, | is typified by the second spices of 
Linnaeus, Seseli montanum, which is the first in Linnaeus of the — 
common to both authors; Sz/eme L. Sp. Pl. 416, a genus adopted fro 
Dillenius with a change of his name Viscago, is weno by Silene cesiied 
the first in Linnaeus of the thirteen species figured by Dillenius; /r7tz/- 
Jaria L. Sp. Pl. 303, a genus adopted from Tournefort, is typified by the 
fifth species of Linnaeus, fritillaria Meleagris, which is one of the three 
species included in /riti//aria by both authors, and is selected from 
these three am it is the one figured by Tournefort. 
(d) When a prebinomial generic name is displaced by the 
(e 
) 
publication of a generic name within binomial usage, the 
application of the displaced name to a species under the 
new aA name designates the type. 
EXAMPLE.—Dianthus L. Sp. Pl. 409, a genus adopted from Tourne- 
fort with a sae as eof his name  Gadatiad: is typified by Dianthus 
Caryophyllus, one of the fifteen original species of Linnaeus. 
The application to a genus of a former specific name of 
one of the included species, designates the type. 
XAMPLES.—Amsonia Walt. Fl. Car. 98 (1788), is typified by 
Taternaenonana Amsonia L., one of its two fey species ; Sordarta 
Ces. & DeN. C + Soc. Critt.. tal, vere is typified by 
Sphaeria Sordoria 1 Fr. r., one of its twelve etka spec 
(/) To avoid change in the current iia: o a Linnaean 
generic name, a well-known economic species may be 
selected as the type, in accordance with the principle 
stated by Linnaeus (Phil. Bot.197. 1751): ‘Si genus 
receptum, secundum jus naturae et artis, in plura dirimi
