Editing Linospadix linospadix (section)

===Other Generic Differences:===
Other generic differences that distinguish
''Linospadix'' from its relatives are not as
clear-cut as is the case with bract attachment.
For example, characters of habit
(solitary or clustering), fruit shape (globose or
elongate), and condition of the mesocarp
(fibrous or non-fibrous) and the endosperm
(homogeneous or ruminate), cannot be used
with certainty for taxonomic purposes.
Floral differences within the related genera
display two classes:
''Calyptrocalyx/Paralinospadix'' usually possess staminate
flowers with an extended pistillode and stamens
with dorsi-fxed, versatile anthers on
long filaments. In ''Howea'', ''Laccospadix'' and
''Linospadix'', staminate flowers lack a
pistillode or it is only small, and stamens
have basi-fixed to subbasi-fixed, non-versatile
anthers on short filaments. These last
three genera are further distinguished by the
condition of the endosperm - it is homogemous in
''Howea'' and ''Linospadix'', and ruminate in
''Laccospadix'' - and the position of
attachment of the peduncular bract is as
described above.
