(Grev.) P.C.Silva & DeCew
(detailed information)


Species Details
Class:	Florideophyceae
Genus:	Ahnfeltiopsis P.C. Silva & DeCew
Species:	Ahnfeltiopsis devoniensis
Authority:	(Grev.) P.C.Silva & DeCew
Description:	Ahnfeltiopsis devoniensis is a small red marine alga growing to only several centimetres in length from a disc-like holdfast. It forms a medium-sized flattened frond with regular dichotomous branching. The branches have parallel sides. The reproductive structures (cystocarps) are internal.

Name History	Adjective (Latin), living in Devon, a county shire in south-western England
Biogeography	NE Atlantic (Britain to Portugal)
Life Cycle	In Ireland, England, northern France and Spain the lifecycle appears to be a succession of diploid female plants forming spores apomictically (that is, without reduction division). However, male and female plants have been found in France and Portugal. Further research is required on this matter.
Uses and compounds	A. devoniensis produce carrageenan (22.3-34.7 κappa, 65.3-77.7 ιota)

Habitat:	Generally found in the very lower intertidal or shallow subtidal, in silty areas protected from strong wave action. As far as it is known, it can be found anytime.
