Family: Convolvulaceae |
Botanical Journal of the Linnean Society (2017) 183: 561–586 Plants robust, usually herbaceous, climbers, rarely lianas or erect shrubs. Leaves usually palmately 5-7-lobed or compounds, rarely simple or reduced to scales. Sepals usually flat, appressed to the corollas, accrescent in fruit; corollas often white or pale yellow, with or without a dark red centre, entirely glabrous, drying with dark lines in mid-petaline bands; anthers spirallly dehiscing; pollen usually trizonocolpate, sometimes 12-zonocolpate. Fruits usually 4-valved capsules, calyces strongly accrescent, the sepals eventually becoming reflect; seeds usually glabrous, sometimes shortly velvety puberulent with dehiscent hairs. Distimake includes 35 species. It is widespread in tropical America and tropical Africa but there are also disjunct species in Asia and northern Australia. Key to the species of Pakistan, Somaliland and Somalia. Key to the species of Distimake in Somaliland and Somalia. Plants robust, prostrate or twining herbs or erect to scrambling shrubs or subshrubs. Leaf blades usually five- to seven-palmately lobed or compound, somtimes linear-oblong to narrowly oblong, sometimes with 2 short-lobes at the base. Calyces usually with flat (not convex) sepals appressed to the bases of the corolla tubes, accrescent in fruit; corollas often white or pale yellowish but varying to cream, orange-brown, salmon-pink reddish, with or without a dark red centre, glabrous, drying with dark lines in mid-petaline bands; anthers spirally dehiscing; pollen trizonocolpate. Fruits four-valved capsules with calyces greatly accrescent, sepals eventuall reflexing; seeds pubescent with short hairs, these confined to near the hilum and the angles in Distimake somalensis. Distimake now (2022-08-06) includes 44 species, and increase from the number of 35 known in 2017. Three grow in Somaliland and Somalia. The above description has been modified to exlcude conditions known only in a few species that do not grow in Somaliland and Somalia and reflect some information in Thulin (2006).
