Agrostophyllum
DESCRIPTION (ORIGINAL JOURNAL ENTRY)Agrostophyllum plants may generally be recognised by having an epiphytic habit, leafy stems, oblique dark-margined leaf sheaths, terminal heads of usually white flowers and a column with eight pollinia.
The species treated here form two broad groups that are both currently placed in the very diverse section Agrostophyllum. The first group has flowers with an essentially bisaccate labellum (i.e. both the hypochile and epichile are saccate or concave) in which the top margin of the hypochile is continuous and not demarcated from the epichile. This group of taxa includes A. javanicum Blume (type of the genus) along with A. boeeanum, A. cyathiforme, A. formosanum, A. galeandrae, A. globiceps and A. maliauense. The second group has flowers with a saccate hypochile but with a distinctly laterally demarcated, ovate to cordate, flattish epichile. This group includes A. asahanense, A. glumaceum and A. pseudolaxum --- Paul Ormerod, "Introduction" Studies of West Malesian Agrostophyllum Blume (Orchidaceae) ,Taiwania, 57(3): 251-262, 2012 |
