Observations.
– An African and Asian species,
Enteropogon prieurii
(Kunth) Clayton
is naturalised in the U.S.A, with records from the states of Alabama and North Carolina (
WCSP, 2014
). No invasive characteristics are reported from this area, but herbarium records suggest that its distribution range is increasing in coastal areas around the Indian Ocean.
Enteropogon prieurii
is likely to be under-recorded due to its striking similarity to the common
Chloris virgata
Sw.
- both species possessing a pale fluffy inflorescence developing black dispersal units consisting of a floret with a caryopsis together with the reduced awned florets.
Enteropogon prieurii
can however be distinguished from
Chloris virgata
by its dorsally compressed (rather than laterally compressed) lower lemma and caryopsis. Recent data suggests that
Enteropogon prieurii
may in fact be better placed in the genus
Chloris
Sw.
(
GRASS PHYLOGENY WORKING GROUP II, 2012
).
