134 Rhodora [JULY 
Vegetable System in 1770 ( 1773 ") where a more detailed description 
is given. 
The variety with enlarged floral bracts, those of the lower flowers 
2 em. long, should be known as S. ovara Hill var. bracteata (Benth.) 
Blake (S. versicolor Nutt. var. bracteata Benth. Labiat. 433 (1832- 
1836)). Specimens have been examined from Texas: Rio Brazos, 
1834, Drummond (type coll.: Brit. Mus.); without definite locality, 
1846, Lindheimer III 492 (Brit. Mus.). 
11. Prasium ? purpureum Walt. p. 166 = PHysosTEGIA purpurea 
(Walt.) Blake (P. denticulata (Ait.) Britton, Mem. Torr. Club, v. 
284 (1894); Dracocephalum denticulatum Ait. Hort. Kew. i. 317 
(1789)). "Two specimens marked Prasiwm are in the Walter Herba- 
rium (p. 87). The right-hand specimen, with sharply mucronate- 
serrate lanceolate leaves, which agrees with Walter's description of 
his Prasium ? incarnatum, is Physostegia virginiana (L.) Benth., 
while the other, with linear-lanceolate crenate-dentate leaves, typi- 
fies Prasium ? purpureum Walt. and is the same as Physostegia denticu- 
lata (Ait.) Britton. 
12. Anonymos caroliniensis Walt. p. 168 = RUELLIA CAROLINIEN- 
sis (Walt.) Steud. Nom. ed. 2. ii. 481 (1841) (as R. carolinensis), 
displacing R. ciliosa Pursh, Fl. ii. 420 (1814). The small-flowered 
variety becomes R. CAROLINIENSIS (Walt.) Steud. var. parviflora 
(Nees) Blake (Dipteracanthus ciliosus (Pursh) Nees y. parviflora, 
Nees in A. DC. Prod. xi. 123 (1847); R. ciliosa Pursh var. ambigua 
Gray, Syn. Fl. ii. pt. 1. 326 (1878); R. ciliosa parviflora (Nees) Britton, 
Mem. Torr. Club, v. 300 (1894)). No specimen. 
13. Anonymos cassioides Walt. p. 171 = SEYMERIA cassioides 
(Walt.) Blake (S. tenuifolia Pursh, Fl. ii. 737 (1814); Afzelia cassioides 
(Walt.) J. F. Gmel. Sys. ed. 13. ii. 927 (1791); Gerardia cassioides 
(Walt.) Pers. Syn. ii. 154 (1806 )). No specimen in Walter Herba- 
rium. Seymeria Pursh (l. c. 736) is a nomen conservandum. 
14. HYPERICUM DENTICULATUM Walt. p. 190 (H. virgatum Lam. 
Eney. iv. 158 (1797); H. angulosum Michx. Fl. ii. 78 (1803). No 
specimen, but the description unquestionably applicable to this 
species. The very narrow-leaved southern form becomes H. DENTI- 
cuLATUM Walt. var. acutifolium (Ell.) Blake (H. acutifolium Ell. 
Sk. ii. 26 (1824); H. virgatum Lam. var. acutifolium (Ell) Coult. 
1 Although the second volume of Persoon’s Synopsis is dated 1807, its first sec- 
tion (pp. 1-272) was issued in the autumn of 1806, as is shown by a review in the 
Regensb. Bot. Zeit. v. 321 (21 Nov. 1806).
