Rupert C. Barneby

82d.  Calliandra haematomma (de Candolle) Bentham var. rivularis (Urban & Ekman) Barneby, stat. nov. C. rivularis Urban & Ekman, Ark. Bot. 24(4): 5. 1932. — "Haiti, Massif du Nord prope Valliere ad Grande Savane ... cr. 250 m alt., m. Majo [1928] flor.: [E. L. Ekman] n. H 9948." — Holotypus, †B; isotypi, K!, NY!.

Shrubby, 1-2 m; lfts glabrous, sometimes pallid; stipular spicules 1-6 mm; petiole of primary lvs 4-12 mm and longer rachises 12-25 mm, the longer interfoliolar segments 2-3 mm; lfts 7-9 pairs, the penultimate 6-8.5 x 1.8-3 mm; calyx glabrous; corolla thinly silky; pods (little known) glabrous or glabrescent.

In riparian thickets, sometimes in pine forest, 120-700 m, locally plentiful in the foothills of Cord. Central in n.-e. Dominican Republic (Libertador, Santiago Rodríguez, n.-w. Santiago) and adj. Haiti (Nord).

Notable for relatively long petioles and ample leaflets, features perhaps reflecting the riparian habitat, but not essentially different in flower or fruit from C. haematomma sens. lat
