Curcuma arida and C. sahuynhensis, two new species from subgenus Ecomata (Zingiberaceae) from Vietnam

Abstract

Two new Curcuma species are described and illustrated from Vietnam. They are compared to their closest allies from subgenus Ecomata. Curcuma arida from Núi Chúa National Park, Ninh Thuận Province, is compared to Curcuma pambrosima and C. vitellina, while Curcuma sahuynhensis from Quảng Ngãi Province is compared to Curcuma xanthella.

Curcuma cotuana sp. nov. (Zingiberaceae: Zingibereae) from central Vietnam

“…Curcuma sahuynhensis differs from C. cotuana by its cream‐white to pale yellow prominently L‐shaped anther (Fig. 4D in Leong‐S kornic kova et al ). The distributions of these species are shown in Fig.…”

“…& N.S.Lý and C. sahuynhensis Škorničk. & N.S.Lý (Leong‐S kornic kova et al ) from Vietnam, and C. corniculata Škorničk. and C. flammea Škorničk.…”

Amomum cristatissimum (Zingiberaceae: Alpinieae), a new species with echinate fruits from central Vietnam

“…Recent extensive explorations of gingers in central Vietnam have led to description of numerous new Zingiberaceae (Leong-Škorničková and Lý 2010, Leong-Škorničková et al 2011, 2015a, b, Lý 2016, 2017a. An interesting species of Amomum with large yellow flowers and echinate fruits was collected during the fieldwork of the first author in 2010-2016 in protected forested areas in Quảng Ngãi province.…”
