Description
Genus Rutaspermum CHANDLER
Text-fig. 9f
M a t e r i a l. USNM PAL 624113.
L o c a l i t y. Dakin.
D e s c r i p t i o n. Seed ovate 2.8 mm long, 2.1 mm wide at widest point with elongate lateral hilum 0.7 mm long; reticulate to punctate sculpture with round fossae.
R e m a r k s. The fossil genus Rutaspermum is used for seeds with rutaceous affinity that cannot be placed into a modern genus. Whereas our seed has a similar shape to other Rutaspermum, the sculpture is more pronounced in our fossil (Gregor 1989). Modern rutaceous genera such as Zanthoxylum can extend from subtropical into temperate latitudes (eFloras 2008–2022).
