- Abstract
The leaf blade anatomy of all species of Neurachne, Paraneurachne and Thyridolepis has been examined, with special reference to features reliably indicative of photosynthetic pathway. Neurachne alopecuroidea, N. queenslandica and N. tenuifolia exhibit C3 anatomy, as do all three Thyridolepis species. Paraneurachne muelleri, N. munroi and N. minor all have C4 anatomy, of the rare ' Alloteropsis-type'. However, all the species exhibit unusual anatomical features, and N. lanigera cannot be confidently assigned as C3 or C, on anatomical grounds alone. Taxonomic considerations confirm that the three genera are closely related to one another in the context of the eu-panicoid assemblage as a whole, and that the genus Neurachne itself, although it exhibits variation in photosynthetic pathway, is not amenable to further taxonomic subdivision.
