96 PENNELL: PLANTS OF THE SOUTHERN UNITED STATES 
ANEILEMA NUDIFLORUM (L.) Kunth, Enum. Pl. 4: 66. . 1843 
Based upon Commelina nudiflora L., citing the second. edition 
of the Species Plantarum, where the species is continued un- 
changed from the first edition. Commelina nudiflora L. (Sp. Pl. 
41. 1753),.‘Habitat in India,” is not to be typified by Her- 
mann’s plant described by Linnaeus in the Flora Zeylanica 
13. 1748, and identified by C. B. Clarke as the species commonly 
known by this name. In the Species Plantarum Linnaeus’s © 
earlier description of this has been modified by the addition of 
the phrase “involucro nullo” and the adoption of the specific 
name “nudiflora,”’ while from photographs kindly sent me through 
the courtesy of Mr. B. Daydon Jackson it appears that all speci- 
mens of this name in the Linnean herbarium in 1753, and inc 
dentally all subsequently added, belong to Aneilema, apparently 
to this species. The combination Aneilema nudiflorum appears not 
to have been formed by Robert Brown (see Prod. 271. 1810); 
as it is usually quoted. Collected along streets of Thomasville, 
Thomas County, Georgia, September 29, 1912, 4737 (P.). 
THE GENUS COMMELINA (Puumter) L.IN THE UNITED 
STATES 
The following revision of this genus in the United States is 
provisional, based upon studies in the field and examination 0 
all material in the herbaria of the New York Botanical Garden, the 
University of Pennsylvania and the Academy of Natural Sciences. 
It is planned to gather at the Garden a living collection, as com 
plete as possible, of all species inhabiting North America, and for 
the accomplishment of this the cooperation of all interested is 
solicited. Mature capsules and seeds, as well as specimens, sent 
to the writer will be appreciated. Perhaps with living plants for 
study several proposed species here reduced to synonymy will 
prove valid. Or, more probably, several here tentatively main- 
tained will be found of varietal rank. At some future date it is 
hoped to attempt a fuller revision.
