摘要

本研究对原产于印度喜马拉雅西北部地区的六种唇形科植物进行了形态组织学研究,这六种植物是:Ajuga integrifolia Buch.-Ham.、A. parviflora Benth.、Pseudocaryopteris bicolor (Roxb. ex Hardw.) P. D. Cantino、Roylea cinerea Baill.、Salvia cana Wall. ex Benth.和 S. coccinea Buc'hoz ex Etl.。首次研究了 A. parviflora、A. integrifolia、P. bicolor 和 S. cana 的组织学特征。据报道,Salvia cana 和 S. coccinea 的连接体高度退化,这在丹参属中是一个不寻常的特征,因为丹参属的典型特征是拉长的连接体形成杠杆机制。在所研究的物种中观察到三种类型的气孔:异形气孔、异形气孔和双形气孔。在这些类群中发现的花粉粒形状从扁球形到近扁球形和扁球形不等,并伴有六方楔形孔。在所研究的物种中发现了 11 种不同类型的毛状体,分为非腺体(5 种)和腺体(6 种)。从这项研究中获得的新见解极大地促进了我们对这些分类群的理解,并弥补了植物学认识中的显著空白,而这些分类群此前一直被忽视。

Morphological and histological analysis of six Lamiaceae species from the North-Western Indian Himalaya
The present work presents a morpho-histological study of six Lamiaceae species, namely Ajuga integrifolia Buch.-Ham., A. parviflora Benth., Pseudocaryopteris bicolor (Roxb. ex Hardw.) P. D. Cantino, Roylea cinerea Baill., Salvia cana Wall. ex Benth. and S. coccinea Buc'hoz ex Etl., native to the North-Western Indian Himalaya region. Histological features have been investigated for the first time in A. parviflora, A. integrifolia, P. bicolor, and S. cana. Salvia cana and S. coccinea are reported to have highly reduced connectives, an unusual trait for the Salvia genus, which typically features elongated connectives forming a lever mechanism. Three types of stomata, anisocytic, anomocytic, and diacytic were observed among the studied species. Pollen grains identified within the taxa exhibit shapes ranging from prolate to sub-oblate and prolate-spheroidal, accompanied by hexa-zonocolpate aperture. Eleven different types of trichomes were identified in the studied species, categorized as non-glandular (5 types) and glandular (6 types). The new insights gleaned from this study contribute significantly to our comprehension and bridge notable lacunae in botanical understanding pertaining to these taxa, heretofore neglected.
