1915] Blake,— Notes on the Genus Sabatia 53 
3. SABATIA FOLIOSA Fernald (S. Harperi Small). After examining 
cotypes of both these species, I have been unable to discover sufficient 
difference between the two to warrant their separation. S. foliosa was 
originally described (Bot. Gaz. xxxiii. 155 (1902)) as having “leaves 
....lanceolate to oblong-lanceolate. . . .2.5 to 6 em. long, 0.5 to 1.2 em. 
broad," “calyx with lanceolate foliaceous lobes 1.2 to 2 em. long," 
and “corolla....with ....oblanceolate remote lobes 1.3 to 2.5 em. 
long." The species was based primarily on Curtiss 5928 from Florida, 
but to it were also referred plants collected by J. D. Smith in South 
Carolina. Later, Harper (Bull. Torr. Club, xxx. 338 (1903)) reported 
it from Georgia (Harper 964, 1196), his specimens being identified 
by Fernald. On these two numbers Small's S. Harperi (Fl. S. E. U. S. 
928, 1336 (1903)) was based. The diagnostic characters of the two 
supposed species, as indicated by Small's descriptions, are as follows: 
S. Harperi: “leaf-blades lanceolate or oblong-lanceolate. . . .1.5-3.5 
em. long....partly clasping....calyx....lobes slightly broadened 
upward, about 4 as long as the corolla....: corolla....lobes....1.5— 
2.5 cm. long." S. foliosa: "leaf-blades....linear-oblong to linear- 
lanceolate or almost linear,....2—6.5 cm. long,....sessile....: calyx 
... lobes linear,....as long as the corolla or nearly so....: corolla 
....lobes 1.2-2.5 em. long." "The non-existence of the differential 
characters here adduced is shown by the following notes taken from 
an examination of Harper 964 (cotype of S. Harperi, in British Mu- 
seum) and Curtiss 5928 (cotype of S. foliosa, in Kew Herbarium). 
Harper 964: leaves (middle and upper) oblong to oblong-lanceolate, 
slightly clasping, 2.5-3.5 cm. long, 8.5-15 mm. wide; calyx-lobes 
spatulate-linear, broadened upwardly, 13.5-15 mm. long, 1.4-2 mm. 
wide; corolla-lobes 14.5-17.5 mm. long (corolla including tube 2.1 cm. 
long). Curtiss 5928:! leaves narrowly oblong to narrowly oblong- 
lanceolate (“linear-oblong to... .almost linear," Small, 1. c.), 3.8-5.3 
em. long, 8.5-10.5 mm. wide; calyx-lobes spatulate-linear, broadened 
upwardly, unequal, 10.5-20 mm. long, 1.8-3.3 mm. wide; corolla- 
lobes 15-16 mm. long (whole corolla 2 em. long). Since neither the 
alleged differences in leaves or those in calyx are borne out by cotypes 
of the two species concerned, S. Harperi must be relegated as a 
synonym to S. foliosa, which has a year's priority. 
1 These measurements are taken from a well-developed specimen. An undeveloped 
one-flowered plant 1.3 dm. high has calyx-lobes 9.5-10 mm. long, and ovate-oblong 
middle leaves 2-2.2 cm. long, 5-7 mm. wide.
