• genus
  • It includes an introductory essay to the genus, as well as full descriptions of all taxa, a series of keys for identification, bibliographies, synonymies and distributional information. (nhbs.com)
  • classification
  • A new suprageneric classification of the Proteaceae, with an annotated checklist of genera" (PDF). (wikipedia.org)
  • For any biological classification system to be effective, it must be stable, universal (i.e., be used by a wide range of people), comprehensive (if too many taxa are unplaced at the level of interest, the classification is of less utility), and it must enhance communication of knowledge by helping us to relate things (Stevens 2006a for references). (mobot.org)
  • leaf
  • Like most other Proteaceae, it has proteoid roots, roots with dense clusters of short lateral rootlets that form a mat in the soil just below the leaf litter. (wikipedia.org)
  • George
  • Although distinct lignotuberous and non-lignotuberous forms of B. ashbyi had long been recognised, they were not formally described as taxa until 2008, when Alex George published the lignotuberous form as B. ashbyi subsp. (wikipedia.org)
  • However
  • However, most plant groups studied in detail (e.g. pines and acacias) have a high percentage of invasive taxa. (jove.com)
  • However, these fungi are often unusual and specific to the Proteaceae, and have proved difficult to classify in the past. (sun.ac.za)
  • unique
  • To address this issue, a phylogenetic analysis of the ITS-1, 5.8S and ITS-2 DNA sequence data was performed to determine relationships between members of the Mycosphaerellaceae and some taxa apparently unique to the Proteaceae. (sun.ac.za)
