horneophyton การใช้

The sporangia of " Horneophyton " contained trilete meiospores, the surfaces of which were decorated with short conical protuberances.
The early Devonian pretracheophytes " Aglaophyton " and " Horneophyton " have structures very similar to the "'hydroids "'of modern mosses.
However, both " Horneophyton " and " Aglaophyton " have been tentatively classified as tracheophytes in at least one recent cladistic analysis of Early Devonian land plants.
The other former " rhyniophytes ", such as " Horneophyton " and " Aglaophyton ", are placed outside the tracheophyte clade, as they did not possess true vascular tissue ( in particular did not have tracheids ).
The presence of soft tissue, including parenchyma, is not observed elsewhere in the fossil record The analysis of rhizomes and rhizoids makes it possible to discern which plants had an active water uptake system ( e . g . " Horneophyton " ), and which were likely to have colonised waterlogged surfaces ( " Asteroxylon " ).
