Commersonia macrostipulata

Commersonia macrostipulata Guymer .

Comparing Commersonia macrostipulata and Commersonia bartramia (both closely related). 
Different sized stipules provides the initial diagnostic feature to observe, check and photograph, for distinguishing these two species.

Relevant quotations from Guymer (2006): 

Commersonia macrostipulata Guymer, 
species nov. affinis C. bartramiae sed ab ea stipulis ovatis vel ovati-lanceolatis, et foliis marginibus leviter serratis et tomento abaxiali subtiliter velutino differt.

Affinities: Commersonia macrostipulata is allied to C. bartramia but differs from this species by its ovate to ovate-lanceolate stipules, and leaves with shallowly serrate leaf margins and finely velutinous abaxial tomentum. 

Etymology: The epithet is derived from Latin *macro-* (large) and *stipulatus* (with stipules), referring to the conspicuous ovate to ovate-lanceolate stipules that characterise the species.

—page: (530) – Commersonia macrostipulata had not been formally described at this time of 2004 
and some botanists still included it within the circumscription of C. bartramia;
some botanists referred to this species as ""Commersonia sp. (Kuranda K.Williams 211)""; 
– it was described later by Guymer, Gordon P. in 2006.
