- Edom (V. Rare)
Description & Remarks
Small creeping shrublet of high desert mountains. Large populations are known from the southern Sinai highlands. We suspect that the plants collected at s. Jordan (Dana reserve) are a smaller desert form of H. lanuginosum, also known from the higher parts of the Judean desert. these two species are distinct in their habit, but it’s hard to find diagnostic differentiating characters between them.
H. sinaicum has smaller, green leaves with short-curly hairs, they are not silvery and elliptic in shape (broadest in the middle, or slightly above). H lanuginosum is a persistent perennial herb with a slightly woody base and erect stiff flowering stems. It’s leaves are larger, ovate-elongate (broadest at their base), and have silvery-white hairs.
In S. lanuginosum’s leaves there is a row of conspicuous black glands along the leaf’s edge, especially in it’s upper part. In H. sinaicum there are only sparse small black glands on the leaf’s lower surface, which are not necessarily at the leaf’s edge, and hard to notice without a loop. furthermore – sepals of H. lanuginosum are more distinctly denticulate than in H. sinaicum, and are less pointed.
