At the same time, a tally of papers on flowers versus those on wood in journals such as Evolution or Systematic Biology shows that while legions of evolutionary biologists and systematists
see interesting issues in flowers, only a handful consider wood.

Mormotomyia hirsuta has long been of great interest to Diptera systematists

In the past, Marshallia has been an intractable genus for systematists
Solving the relationships among taxa in complexes that have experienced these phenomena presents a unique challenge for systematists

can readily distinguish Clavariadelphus from other clavarioid, cantharelloid, craterelloid or gomphoid members of Aphyllophorales (Donk, 1933; Corner, 1950, 1970; Wells and Kempton 1968; Petersen, 1972; Petersen et al.
