庆元香科科,浙江唇形科一新种

该文描述了采自浙江南部庆元县的唇形科(Lamiaceae)香科科属(Teucrium L.)一新种:庆元香科科(T.qingyuanense),并附有线描图。庆元香科科与峨眉香科科(T.omeiense)和香科科(T.simplex)接近,与峨眉香科科的区别在于其茎、花序轴和花梗均密被倒向短柔毛,花萼外面被短柔毛和腺点或腺毛,花冠外面密被腺毛和柔毛,花柱疏被腺毛;与香科科的区别在于茎、花序轴和花梗均密被倒向短柔毛,花萼外面被短柔毛和腺点或腺毛,下唇2齿狭三角形,先端急尖,花冠外面密被腺毛和柔毛,中裂片宽卵形,先端急尖。基于对茎、叶、花萼毛被的扫描电镜观察和ITS序列的系统发育分析均支持庆元香科科作为独立的种。

Teucrium qingyuanense, a new species of Lamiaceae from Zhejiang, China

Teucrium qingyuanense, a new species of Lamiaceae from Qingyuan County, Zhejiang Province of East China, is here described and illustrated. The new species resembles T. omeiense and T. simplex, but it differs from the former in having stems, rachises and pedicels densely retrorse-pubescent, calices outside pubescent and glandular or glandulose, corolla outside densely glandulose and pubescent, styles sparsely glandulose. It differs from the latter in having stems, rachises and pedicels densely retrorse-pubescent, calices outside pubescent and glandular or glandulose, 2 teeth of lower lip narrowly triangular, apex acute, corolla outside densely glandulose and pubescent, middle lobe broadly ovate, apex acute. SEM observation on indumentum of stems, leaves and calices, together with phylogenetic analysis of ITS sequences supported T. qingyuanense as a distinguished and independent species.
