The Latin specific epithet of ''axilliflora'' refers to ''axillary'' meaning borne in or arising from the axil (the junction of leaf and stem) and also 'flora' meaning flower. Both genus and species were first described and published in Novon The Missouri Botanical Garden is a botanical garden located at 4344 Shaw Boulevard in St. Louis, Missouri.

Marshall Conring Johnston
Marshall Conring Johnston (born May 10, 1930) is an American botanist who made several explorations in Mexico and specialized in plants in the family Gesneriaceae. Johnston was born in San Antonio in the family of Theodore Harris Johnston and Lucile Mary Conring. He went on his first botanical expeditions to Mexico while still in high school during 1945-1947. On those trips he visited the northern Mexican states of Tamaulipas, Nuevo Leon, Coahuila, Durango, and Zacatecas. From 1972-1974 he made trips to Chihuahua, concentrating on desert flora. These early 1970s trips resulted in the bulk of his botanic collection. Marshal participated in the creation of the books ''Flora of Texas'', ''Flora of North America'', and ''Flora Neotropica''. Johnston was also a professor at the University of Texas at Austin.

Rhamnaceae
The Rhamnaceae are a large family of flowering plants, mostly trees, shrubs, and some vines, commonly called the buckthorn family. Rhamnaceae is included in the order Rosales. The family contains about 55 genera and 950 species. The Rhamnaceae have a worldwide distribution, but are more common in the subtropical and tropical regions. The earliest fossil evidence of Rhamnaceae is from the Late Cretaceous. Fossil flowers have been collected from the Upper Cretaceous of Mexico and the Paleocene of Argentina. Leaves of family Rhamnaceae members are simple, i.e., the leaf blades are not divided into smaller leaflets.Flowering Plants of the Santa Monica Mountains, Nancy Dale, 2nd Ed. 2000, p. 166 Leaves can be either alternate or opposite. Stipules are present. These leaves are modified into spines in many genera, in some (e.g. ''Paliurus spina-christi'' and '' Colletia cruciata'') spectacularly so. ''Colletia'' stands out by having two axillary buds instead of one, one developing int ...

The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' ( non, Hróðr) "fame, glory, honour, praise, renown" and '' berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe it entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto.
