摘要
根据《爪哇植物志》，爪哇只有一种Evolvulus alsinoides。从那以后，2017年在西爪哇德波的印度尼西亚大学报告了第二个物种，作为外来归化物种。最近进行了一些野外研究，以提供岛上该属的最新分类信息。实地观测于2019年3月至12月在万丹、雅加达、西爪哇、日雅加达和东爪哇进行。植物标本室的研究也在波哥大植物标本室、茂物植物园植物标本室、班敦根斯植物标本室和印度尼西亚大学生物系植物标本室进行。我们的研究揭示了爪哇地区新记录的一种已被人工栽培的Evolvulus，即E. glomeratus Nees & Mart。无性系种群。桔梗(桔梗属)此外，据报道，在西爪哇的其他地点也发现了nummularius Evolvulus，并向中爪哇扩展。提供了爪哇Evolvulus的更新关键，对两个物种的描述，照片和简短的讨论。
A Note on The Genus Evolvulus (Convolvulaceae) In Java, Indonesia
According to the Flora of Java, there is only one species of Evolvulus in Java, namely Evolvulus alsinoides. Since then, a second species was reported in 2017 from Universitas Indonesia, Depok, West Java, as an alien naturalized species. Some recent field studies have been conducted to provide updated taxonomic information of the genus on this island. The field observations were carried out in Banten, Jakarta, West Java, Jogjakarta, and East Java from March to December 2019. The herbarium studies were also conducted in Herbarium Bogoriense, Herbarium of Bogor Botanic Gardens, Herbarium Bandungense, and Herbarium of the Department of Biology, Universitas Indonesia. Our study reveals one newly recorded species of Evolvulus in Java already grown in cultivation, namely E. glomeratus Nees & Mart. subsp. grandiflorus (Parodi) Ooststr. Besides that, Evolvulus nummularius is now also reported to occur in other sites of West Java and extended to Central Java. An updated key to Evolvulus in Java, descriptions to both species, photographs, and brief discussions are provided.
