Rissoa Arn. (sec. Swingle and Reece 1967)

Cultivar or Taxon


Atalantia Corrêa (sec. Swingle and Reece 1967, Bayer et al. 2009; sensu Tanaka sec. Cottin 2002)



Crown compact or dense, not weeping. First year twig surface glabrous; second or third year twig surface striate; thorns straight; prickles absent or not persistent. Petiole glabrous, length short or medium, wings absent. Leaflets one, margins entire, shade leaflet blades weakly conduplicate, sun leaflet blades weakly conduplicate. Leaflets sweetly orange-like (?) or somewhat to strongly malodorous when crushed. Fruit broader than long, rind light green with some break to yellow (5), green-yellow (6), yellow (7-10) or yellow-orange (11), firmness leathery, navel absent.

Swingle and Reece (1967) provided the following additional notes on the genus:

"Stamens connate, forming a cylindric tube, or connate in groups, rarely free; fruits with numerous well-developed, juicy pulp-vesicles that fill all the space in the fruit not occupied by the few medium-sized seeds; stipuloid paraphylls absent.

Seven of the species of Atalantia fall in this subgenus. In general they much resemble the species of the subgenus Rissoa."
