Plants usually perennial, occasionally
annual in desert areas; cespitose and shortly rhizomatous. Culms 5-120
cm, unbranched. Leaves mostly basal; ligules of hairs; blades
2-5 mm wide. Inflorescences terminal, exceeding the upper leaves, dense,
cylindrical to ovoid panicles, occasionally reduced to racemes; branches
short, non-disarticulating; rachises concealed by the spikelets; disarticulation
beneath the glumes. Spikelets laterally compressed, with 2-4 florets, only
the basal florets bisexual, the next 2 florets usually staminate, the fourth floret,
if present, sterile. Glumes subequal, clearly exceeding the florets, awned
or unawned; lemmas firmly membranous, 3-veined basally, 5-7-veined distally,
mucronate to shortly awned, awns shorter than 10 mm; anthers 3; ovaries
glabrous. x = 10. Named for Carl Anton Fingerhuth (1798-1876), a German
botanist and physician.
Fingerhuthia is a genus of two species, one native to southern Africa and
western Asia, the other endemic to southern Africa. One species has been grown
in the Flora region.
1. Fingerhuthia africana Lehm.
Thimblegrass, Zulu Fescue
Plants cespitose and shortly rhizomatous. Culms 10-95 cm. Blades
2.5-40 cm long, 2-4 mm wide, scabrous distally. Panicles 1.5-5 cm, cylindrical
or ovoid, cuneate below. Spikelets 4-5.5 mm. Glumes narrowly elliptic,
ciliate on the keel and the distal portion of the margins; lowest lemmas
3.5-4 mm, glabrous, sometimes scabridulous, margins ciliate, apices obtuse and
abruptly mucronate. 2n = 40.
Fingerhuthia africana is native to southern Africa and western Asia. It
has been grown at the Santa Rita Experimental Range in Pima County, Arizona, but
is not established in the Flora region.
