The protologue indicated a collection of Tracy in Reno, which is housed at US and cited above. The number 216 on the label of the US specimen was added by a later worker. Hitchcock (1939: 613), evidently working from Leptochloa tracyi (Vasey) Beal, Grass. N. Amer. 2: 436 (1896), believed lectotypification was necessary given the citation of two collections (of Tracy and Palmer and each of these assigned the number 619 by some later worker) in the work by Beal. However, Vasey’s description included a description of the newly proposed species, in addition to citation of a specimen collected by Tracy and made no reference to Palmer’s collection, so lectotypification was unnecessary. Zanoni ([NY-1144033]) in 2010 also made reference to this on an annotation slip.

Phenology.

Flowering mostly May to October in North America and throughout the year in South America during and after warm and wet seasons.

Distribution.

Southern Canada (infrequently) through USA (where most common) south sporadically to Paraguay. The transition between the native and non-native distribution of L. fusca subsp. fascicularis is somewhat uncertain, particularly in its sourtherly range. Elevation from sea level to 2300 metres. Native: Most of the United States mainland (excluding Georgia) north to Ontario, Canada, occurring irregularly to about 40°S in Argentina. (TDWG: in North America in part or all of regions 73-80 (see additional specimens for additional detail): BLZ, COS, HON; 81: BAH, CAY, CUB, DOM, HAI, JAM, LEE-NL, LEE-VI, TCI; 82: VEN; 83: BOL, COL; 84: BZC, BZE, BZL, BZS; 85: AGE, AGW, AGW, PAR. Non-native: TDWG: CZE. Collected once from a railyard in Vancouver, British Columbia but not persisting (F. Lomer, pers. comm. 2010). Possible occurrences in Saskatchewan and Quebec have not been confirmed.

Conservation status.

Least Concern ( IUCN 2012), given its wide distribution and abundance.

Etymology.

Possibly in reference to the fasciculate (bundled or clustered) arrangement of the lower panicle branches before they are exserted from the sheath.

Vernacular names.

bearded diplachne; salt meadow grass; zacate salado lagunero; salado fasciculado.

Comments.

Specimens from Florida and the Bahamas typically have the shortest spikelets (e.g. Vincent 16032 [MU]; Davis s.n. [FLAS 38436]; Craighead s.n. [FLAS 84837]; Herndon 905 [RSA]). On rare occasions, a specimen growing in a saturated soil may branch and root so vigorously at nodes that it appears to be stoloniferous (e.g. Fleetwood 12215 [SMU]). Older specimens from Reno, Nevada, identified as Diplachne tracyi Vasey, have narrow, relatively long and somewhat cylindrical spikelets (e.g. the type specimen), but since this spikelet morphology recurs in the species complex from parts of Africa and Australia and is narrowly distributed, this variant is unworthy of taxonomic recognition. Those specimens may be waifs of D. f. subsp. fusca from the Paleotropics, but genetic analyses would be necessary to test this hypothesis. Some specimens from California (Twissleman 6491 [MO]) also closely resemble some forms of D. fusca subsp. fusca .

A morphotype in the United States described as Diplachne acuminata Nash in Britton has been recognised based on the relative elongation of glumes and lemmas and awned lemmas (Gleason, 1968: 188; Gleason and Cronquist, 1991: 785). Diplachne maritima E.P. Bicknell was described based on its prostrate habit, more pronounced lemmatal awns and ecological occurrence in brackish coastal areas from Massachussetts to Florida (e.g. Weatherby 4390; Commons 155; Metcalf 5717; Torrey 8765; Williams 3102 [all at US]) and around saline areas in Onondaga and Cayuga counties, New York (e.g. Leonard 8559 [FLAS]; Congdon s.n. [RSA]; Perkins s.n. [RSA], Fogg 3889 [MO]). However, given that three of the four subspecies of Diplachne fusca , recognised in this treatment, have moderate to high levels of salinity tolerance (but little evidence for this with subsp. Diplache fusca uninervia ) and that populations with elongated awns often occur elsewhere, such as in the Distrito Federal and Estado de México ( Jiménez-Osorino 40 [RSA]; Mattuda 25656 [MEXU, MO, MU]; Espinosa & Sarukhán 318 [ENCB, MEXU, MO]; Rzedowski 26251 [ENCB, MO]; Rzedowski 28145 (ENCB, US); Villegas 585 [ENCB]; Rzedowski 20432 [ENCB], Schaffner 49 [W]), taxonomic recognition of specimens with longer than average lemmatal awns also is unwarranted.

Specimens have not been confirmed for this subspecies listed on websites from Sweden (e.g. Lackalänga, year 1949 [LD, S]) and Poland (Vogel, years 1916 and 1918 [OHN]).

Diplachne fusca subsp. facicularis is more widespread in North America than subsp. Diplachne fusca uninervia , although the latter is more invasive outside of its range (e.g. Snow & Simon 1999). Specimens morphologically intermediate beween D. f. subspp. Diplachne fascicularis and Diplachne uninervia occasionally are seen (Hitchcock 93 [TEX]), but the taxa maintain their distinct morphology in sympatry (e.g. Snow 5899 and 5900 at Falcon Lake, Zapata County, Texas).

Sutton (1973a) briefly described the anatomy of D. fascicularis (as " Leptochloa fascicularias ") and placed Leptochloa into the tribe Chlorideae ( Sutton 1973b), but these papers extrapolated the limited analysis beyond their usefulness. Clifford and Watson (1977) illustrated D. fusca subsp. fusca (as Diplachne parviflora ). Renvoize (1984) illustrated the midrib of D. fusca and discussed its prominent air canal, but cited no voucher.

Characters of Diplachne fusca subsp. fascicularis that generally differ from those of subsp. Diplachne fusca uninervia include: lower panicle branches inserted in sheath, a greater tendency for sheaths to be mottled with anthocyanins (e.g. McGregor 12652 [KANU, US]), the tip of the uppermost leaf blade often extending beyond the apex of the panicle and the lemmatal apices generally acute to acuminate and sometimes mucronate on the lateral nerves. Specimens of D. f. subsp. fascicularis with exserted panicles bearing relatively short, somewhat flexuous branches (Morello and Cuezzo 1124 [BAA])) can resemble Dinebra scabra (Nees) P.M. Peterson & N. Snow. Relatively erect specimens of Dinebra viscida (Scribn.) P.M. Peterson & N. Snow are often confused for D. f. subsp. fascicularis where the species overlap, but the panicle length and width of the former are usually significantly shorter and the fresh foliage is slightly sticky or viscid.
