High Quality Content by WIKIPEDIA articles! The Bambusoideae is a subfamily of the true grass family Poaceae, and is characterized by having 3 stigmas and are mostly tree-like. However, there are uncertainties at practically every taxonomic level within the Bambusoideae, and different types of data (floral morphology, vegetative structures, anatomy, and genetics) often result in support for differing relationships. The Bambusoideae generally consists of a distinct “core” group of genera, the woody bamboos (Bambuseae)and an associated group of genera of questionable affinity, the herbaceous Bambusoideae. The bamusoid taxa have long been considered the most “primitive” grasses, mostly because of the presence of bracteate, indeterminate inflorescences, “pseudospikelets,” and flowers with three lodicules, six stamens, and three stigmas. In a recent study (Clark et al., 1995) DNA sequences for the chloroplast gene ndhF were analyzed to address phylogenetic relationships among the major...
