Plants perennial; synoecious; rhizomatous,
occasionally also stoloniferous. Culms 2-80 cm, hard, persistent, branched
above the base. Ligules membranous, ciliate, cilia as long as or longer
than the basal membrane; blades linear-lanceolate, becoming rolled, hard,
and sharp-pointed. Inflorescences terminal, exceeding the upper leaves,
panicles of racemosely arranged, spikelike primary branches; primary branches
woody, not disarticulating, apices hard, sharp; secondary branches shorter
than 1 cm, otherwise similar to the primary branches, sometimes clustered. Spikelets
7-16 mm, laterally compressed, with 3-16(20) florets; florets bisexual;
disarticulation above the glumes and beneath the florets. Glumes
more or less equal, markedly exceeded by the florets; lemmas 3-veined,
unawned; lodicules 2; anthers 3. Caryopses glabrous. x
= unknown. Name from the Greek klados, branch, twig, or stem, and rhaphis,
needle, alluding to the sharp-pointed inflorescence branches.
Cladoraphis is a southern African genus of two species, both of which grow
in open, xeric, sandy habitats.
1. Cladoraphis cyperoides (Thunb.) S.M. Phillips
Bristly Lovegrass
Culms 2-80 cm. Blades 2-11 cm long, 4-9 mm wide, margins ciliate
basally. Primary branches to 8 cm, widely spaced, often separated by more
than their own length. Spikelets with 4-9(20) florets, densely clustered,
appressed to and concealing the branch axes; lemmas about 3.5 mm. 2n
= unknown.
Cladoraphis cyperoides was once collected on a ballast dump at Linnton (near
Portland, Oregon). It is not known to have persisted in North America. The spinelike
leaves and panicle branches would probably make an encounter memorable.
