Abstract

Curcuma ubonensis Boonma, Saensouk, Maknoi & P. Saensouk sp. nov. (Zingiberaceae) was recently discovered in Ubon Ratchathani Province, Eastern Thailand. Specimen identification involves comparing their morphology with descriptions in similar species' protologues. We performed measurements on specimens collected from their natural habitats, both living and preserved. Despite its resemblances with Curcuma prasina Škorničk. in having greenish inflorescence with small purple flowers that lack of epigynous glands, yet this novel species displays distinct features of a brownish-red margin of petiole (vs. C. prasina has green margin), lamina elliptic, 3.8-7.0 cm wide, margin brownish red (vs. narrowly elliptic, 1.5-3.2 cm wide, margin green); coma bract present (vs. absent), fertile bracts uniquely triangular-obovate, apex rounded (vs. almost orbicular, apex acute), and labellum reddish purple with four white stripes by two stripes rarely pale yellow extending from the basal to half of the sinus, and another two stripes from the basal along the longitudinally of each lobe to half the length of the lobe, with yellow at the middle groove of the labellum almost to the base (vs. purple with a bright yellow and swollen median band composed of two central lines extending from the base to about two-thirds the length of the labellum towards the apex, sides of the labellum with paler lines radiating towards the margin). Meticulous examination and morphological comparison of Curcuma ubonensis with related species within the Curcuma genus reveals its novelty. We comprehensively accounted for its morphological traits, including illustrations, vernacular name, ecological preferences, phenology, distribution, traditional uses, conservation status, distribution map, and a comparative table to its ally species. Furthermore, we present an updated identification key for differentiating species within the Curcuma subgenus Hitcheniopsis in Thailand.

Curcuma ubonensis (Zingiberaceae), a new species of Curcuma subgen.

Curcuma ubonensis Boonma, Saensouk, Maknoi & P. Saensouk sp. nov. (Zingiberaceae) 最近在泰国东部的乌汶叻差他尼府被发现。标本鉴定需要将其形态与类似物种的原型描述进行比较。我们对从其自然栖息地采集的活体和保存标本进行了测量。尽管它与莪术（Curcuma prasina Škorničk.）有相似之处，都是绿色花序，紫色小花，没有副雌蕊腺体，但这一新种的叶柄边缘呈棕红色（相对于莪术（Curcuma prasina Škorničk.）的绿色边缘）。C. prasina 的边缘为绿色），叶片椭圆形，宽 3.8-7.0 厘米，边缘棕红色（vs. 狭椭圆形，宽 1.5-3.2 厘米，边缘绿色）；有苞片（vs. 无），可育苞片呈倒卵形三角形，先端圆形（vs.几乎圆形，先端锐尖），唇瓣红紫色，有四条白色条纹，其中两条很少为淡黄色，从基部延伸到凹缺的一半，另两条从基部沿每个裂片的纵向延伸到裂片长度的一半，唇瓣中间凹槽处的黄色几乎延伸到基部（vs.紫色，中间有一条由两条中心线组成的鲜黄色膨胀带，从基部向先端延伸至唇瓣长度的三分之二处，唇瓣两侧有向边缘辐射的浅色线）。通过对莪术（Curcuma ubonensis）与莪术属相关物种进行细致的检查和形态学比较，我们发现了莪术（Curcuma ubonensis）的新颖性。我们对莪术的形态特征进行了全面的描述，包括插图、白话名称、生态喜好、物候、分布、传统用途、保护现状、分布图以及与其同属物种的比较表。此外，我们还提供了一个最新的识别钥匙，用于区分泰国莪术亚属中的物种。

期刊介绍： Notulae Botanicae Horti Agrobotanici Cluj-Napoca is a peer-reviewed biannual journal aimed at disseminating significant research and original papers, critical reviews and short reviews. The subjects refer on plant biodiversity, genetics and plant breeding, development of new methodologies that can be of interest to a wide audience of plant scientists in all areas of plant biology, agriculture, horticulture and forestry. The journal encourages authors to frame their research questions and discuss their results in terms of the major questions of plant sciences, thereby maximizing the impact and value of their research, and thus in favor of spreading their studies outcome. The papers must be of potential interest to a significant number of scientists and, if specific to a local situation, must be relevant to a wide body of knowledge in life sciences. Articles should make a significant contribution to the advancement of knowledge or toward a better understanding of existing biological and agricultural concepts. An international Editorial Board advises the journal. The total content of the journal may be used for educational, non-profit purposes without regard to copyright. The distribution of the material is encouraged with the condition that the authors and the source (Notulae Botanicae Horti Agrobotanici Cluj-Napoca or JCR abbrev. title Not Bot Horti Agrobo) are mentioned.
