This is the only species found to the west of Wallace’s Line, occurring in the southern part of Thailand, Malay Peninsula, Sumatra and Borneo. (Ch.D. Heatubun, A monograph of Cyrtostachys (Arecaceae). 2009)

Discussion

  • Cyrtostachys renda differs from all other species in the bright red crownshaft and leaf sheath, the lowest number of leaflets (26 – 40 on each side), the leaflets being waxy white abaxially, the inflorescence branched mostly to 2 orders (possibly up to 3), the tectum surface of pollen rugulate, and its preferred habitat in lowland peat swamp forest in southern Thailand, Malay Peninsula, Sumatra and Borneo. In the protologue of Cyrtostachys renda, no material is cited although a reference is made to Blume’s account in Rumphia, published some years later, in which the Korthals specimen is mentioned (Blume 1838, 1843). We formally designate this specimen as lectotype. In the case of C. lakka, Beccari (1885) cited two specimens, Beccari PB 2674 and 4038, both of which are extant at FI. Harold E. Moore annotated Beccari PB 2674 (FI) as lectotype in 1956, but to our knowledge did not publish this lectotypification. We have formalised this typification here. The transfer of Cyrtostachys lakka to a synonym of C. renda has already been made by Whitmore (1982). The bright green stems and brilliant red to orange crownshafts make Cyrtostachys renda a highly desirable and widely cultivated ornamental. Infraspecific taxa have been described from cultivation and the number of these could increase in parallel to horticultural demand. Ellison & Ellison (2001) introduced two cultivars, C. renda ‘Apple’ and C. renda ‘Orange Crownshaft’, followed by Waddel (2002) with his C. renda ‘Theodora Buhler’. Before them, Tucker (1992) reported, that in Singapore Botanic Garden grew C. renda ‘Ruby’ and that it was one of the most treasured specimens of all, and he also discussed a strange brown crownshafted form of C. renda in Florida. All the cultivars of C. renda were described based on different stem and crownshaft colours. (Ch.D. Heatubun, A monograph of Cyrtostachys (Arecaceae). 2009)
