Correction of Salix L. [Salicaceae] in the flora of Jabal An-Nabi Shu'ayb, Sana'a Governorate, Yemen

In 1997, J. R. I. Wood identified Salix sp. collected from the stream, located at the southwest part of Jabal An-Nabi Shu'ayb, as Salix mucronata Thunb. In this paper, the identity of the only Salix sp. founded in Jabal An-Nabi Shu'ayb is Salix excelsa Gmel, which is elucidated by providing photos and morphological description. Specimens collected from the same locality were compared with the description of S. mucronata cited in Flora Capensis, Flora of Arabian Peninsula and Socotra and Flora of the Kingdom of Saudi Arabia. It is clarified that a misidentification was made by J. R. I. Wood. Thus the correct name for Salix species, found in the flora of Jabal An-Nabi Shu'ayb as described, is Salix excelsa Gmel. But not S. mucronata Thunb. as cited by J. R. I. Wood 1997.

Notes on the flora of Yemen. 1: morphological and anatomical studies on Cuscuta planiflora Tenore, [Cuscutaceae] collected from Jabal An-Nahi Shn'ayb, Sanaa, Yemen with the reference of its phytogeographical distribution

Cuscuta planiflora is a parasitic plant on numerous plants from different families such as Lamiaceae [Thymus laevigaus], Acanthaceae [Hypoectes forsskalii] and Dipsaceae [Pteracephalus frutescens]. Morphological, anatomical and phytogeographical studies were carried on the Cuscuta planiflora which was collected from Jabal An-Nabi' Shu'ahyb located 30 km west of Sanaa the capital of Yemen, with coordinates [043° 58[-]-043° 59 E and 15° 14[-]-15° 15[-] N]. the morphological study includes stem morphology and floral structure. Anatomically, the cross, lateral section of the stem and lateral section of the haustoria's area, were studied, Phytogeographical studies were done by studying its distribution in Yemen and in plant geographical regions
