| Metapleuron dull coriaceous, with adpressed pilosity in slightly more than posterior half. |
| Carapace covered in adpressed colourless hairs, with long brown bristles near eyes and some whitish hairs on eye field. |
| The cone specimens are mostly compressed or adpressed in preservation but their carbonized remains contain ribbed pollen. |
| The sharp angle between the blade and the basal facet suggests that, like the palmate sclerites of H. evangelista, they were adpressed to the body surface. |
| They also bear prominent ribs and are tightly adpressed to the body, but are larger than the palmate sclerites. |
| Pfefferkorn erected the morphogenus Artisophyton for adpressed specimens of this type showing indented vascular bundles. |
