Although Dichromena has a single capitate inflorescence per culm and Psilocarya had an open paniculate inflorescence, they do have features in common: large spikelets that bear multiple achenes, and achenes that are usually rugulose
and without hypogynous bristles.
Median tergite 1 is usually rugulose
to weakly coriaceous anterior to spiracles and smooth posterior to spiracles or entirely smooth (97.
In Centruroides exilicauda (Wood 1863), the position of VA is occupied by a V-shaped rugulose
sculpturation, not well defined, which leaves [Eb.

Inflorescence laxly paniculate, broadly pyramidate, tripinnate at base and bipinnate toward the apex, 65-70 cm long, 20-45 cm in diameter at base, erect, rachis white lanate but soon glabrous, dark purple-wine, rugulose

The pollen grains were reported as trizonocolporate (tricolporate), prolate spheroidal, oval in meridional view, 25-50 microns in size and with lalongate ora (pores) and a surface patterning ranging from obscure - psilate - striate - rugulose
