WEAKLEY FLORA
SCIENTIFIC NAME: Acaciella hirta
COMMON NAME: Prairie Acacia
SYNONYMY: [= S; < A. angustissima var. angustissima - FNA, Y; = Acacia angustissima (P. Miller) Kuntze var. hirta (Nuttall) B.L. Robinson - I, K1, SE, WH3, Z; = Acacia hirta Nuttall]
PHENOLOGY:
HABITAT: Sandhills, disturbed sandy areas.
COMMENTS: W. LA, AR, and MO west to KS, OK, TX and Mexico; disjunct in e. Panhandle FL and n. peninsular FL. Isely (1969) mentions that the status of Florida material referred to [Acacia angustissima] var. hirta is problematic. To my knowledge, these populations are disjunct by several hundred miles from the other forms of the species… There seems no morphological differentiation except for the fact that most (but not all) of my rather limited Florida material represents the glabrate extreme of var hirta. Isely (1969) also gives the flowering dates as May-July for the latitudinally similar main range of the hirta entity, but August-September for Florida. Rico & Bachman (2006) in a rangewide assessment of the genus take a broad approach to the Acaciella angustissima complex (a very variable taxon) and include our material in A. angustissima var. angustissima, defined to include material from se. United States, sw. United States, Mexico, Central America, and South America, but they apparently did not see any material from se. United States in their monograph. Further study using modern techniques is needed.
