Myrtaciphyllum eremeaensis
Taxonomy
Myrtaciphyllum eremeaensis was named by Christophel et al. (1992) [Specimen NC 1017, University, as one mummified leaf and one cuticle slide (NC-C 1017).
Type Locality: Nelly Creek, S.A. (29°19'S, 137°18' E).]. It is considered to be a form taxon. Its type specimen is Holotype: NC 1017, housed in the Palaeobotany Collection, Botany Department, Adelaide University., a leaf (Cuticle), and it is a compression fossil. Its type locality is Nelly Creek, which is in an Eocene floodplain sandstone/claystone in the Eyre Formation of Australia.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| D. C. Christophel et al. 1992 | Architectural features: leaf shape elliptic, ovate or obovate. Size range: 3.5-13 cm long by 1.5-4 cm maximum width. Leaf tip acute or attenuate, rarely acuminate. Leaf base acute, rarely obtuse. Primary venation pinnate, secondary veins straight, brochidodromous with a prominent intermarginal vein. Cuticular features: leaves hypostomatic, stomatal complex anomocytic, with between three and six subsidiary cells (three or four most common). Anticlinal epidermal cell walls angular - straight to slightly curved. Cells of both upper and lower epidermis equal sized; no striations visible on periclinal walls. Simple hairs infrequent (less than three per mm2) on both surfaces. Hydathodes rare on lower (abaxial) epidermal surface, apparently absent on
adaxial (upper) surface. Lid cells numerous on both surfaces with S-shaped to straight sinus showing no beaded thickening or perforations. Epidermal cells surrounding lid cells frequently modified into a somewhat radial pattern - particularly on upper epidermis. |
