摘要

Aeschynanthus luteoflorus (Gesneriaceae) is here described as a new species from Kalimantan, Indonesia, adding to the diversity of Aeschynanthus in Borneo.该物种的花序形态与 A. dasycalyx Hallier f 相似。但其特征是椭圆形,有时长圆形的叶子,卵状椭圆形的小苞片,以及棕色至亮绿黄色的管状杯状花萼。它的另一个不同之处在于具有明亮的黄绿色和更长的花冠。该新种与 A. flavidus Mendum 和 P. Woods 的区别还在于它的叶子呈椭圆形,有时呈长圆形,花萼为管状杯状,花冠明显较短,约为花萼长度的 1.5 倍。 Notes on distribution, ecology, conservation status, and comparative illustrations are provided.

Aeschynanthus luteoflorus Zainudin, Idris & Yudistira,sp.十一月

诊断:A. luteoflorus is similar to A. dasycalyx Hallier f., but differs in having elliptic, sometimes oblong leaves (vs. ovate); ovate-elliptic bracteoles (vs. linearlanceolate); and a tubular-cupuliform calyx (vs. ovatesubcylindrical to sub-urceolate) that is brown to bright greenish yellow (vs. shiny blackish blue). Furthermore, it possesses a longer corolla (2.3–2.5 cm vs. 1.8–2 cm), that is bright greenish yellow (vs. vivid red). A. luteoflorus also differs from A. flavidus Mendum & P.Woods, another yellow-flowered species from Borneo, by its elliptic, sometimes oblong leaves (vs. narrowly to broadly elliptic), tubular-cupuliform calyx (vs. tubular to infundibuliform), and a significantly shorter corolla (2.3– 2.5 cm vs. 5.5–6.3 cm) that is approximately 1.5 times the calyx length (vs. >2 times) (Table 1).
