狮耳草属--中国唇形科植物一新归化属
Leonotis, a newly naturalized genus of Lamiaceae in China
摘要
Abstract
Leonotis nepetifolia (L.) R.Br.(Lamiaceae), a naturalized species was first found in China.The naturalization of this species represents that the genus Leonotis (Pers.) R.Br.was firstly recorded from China.Leonotis is characterized by its axillary verticillasters, bracteoles and calyx teeth needle-like at apex, flowers orange or yellow, and the upper corolla lip longer than the lower one;it is the most similar to the genus Leucas R.Br., but the latter has almost equal calyx teeth, flowers white, corolla tubes not exceeding the calyx, and the upper corolla lip shorter than lower one.Leonotis nepetifolia is an annual herb.Its verticillasters are usually globular, and with dense flowers and bracts;bracteoles are linear, and slight curving, acute at apex.Calyxes are tubular, swollen and slightly curving at apex;Calyx teeth are needle-like at apex, the adaxial lobes are larger then the others.Corolla are orange, and with orange or whitish-yellow hairs;Corolla tubes are slender, and extend from calyx;Corolla limb is 2-lipped, the upper lip is larger than the lower one.Leonotis nepetifolia is the most similar to Leonotis leonurus R.Br., but the former has oval or cordate leaves, in contrast the latter has lanceolate leaves.An amplified taxonomic description, discussion on the geographical distribution, resource value, domestication approach, reproduction and harm, and related photos are provided in this study.关键词
