Krauss who undertook a collecting trip to South Africa from 1838 to 1840.[1] DescriptionThe trees are semi-deciduous, as spring leaves only partially replace old foliage. These forest trees become conspicuous in late spring, when the fresh leaves turn to a pale, almost white colour, before returning to green by mid-summer.[3] In winter the foliage turns partially red or purple, which is shed just before flowering starts.[4] The fresh clusters of four-winged fruit are a colourful red or yellowy red colour, before they dry to mid-brown.[3] BiochemicalCombretastatin B-1, a type of stilbenoid, can be found in C. kraussii.[5]RelationshipsIt is closely related to Combretum nelsonii[2][4] which occurs in rockier habitats, and bears a resemblance to the larger leaved Combretum woodii, which is similarly distributed, but in bushveld.[2] GalleryReferences1. ^1 {{cite web | last = Le Roux | first = Lou-Nita | title = Combretum kraussii | url= http://www.plantzafrica.com/plantcd/combretkraus.htm | accessdate = 14 October 2011|display-authors=etal}} {{Commons category}}{{Taxonbar|from=Q5150961}}2. ^1 2 {{cite book | last = Van Wyk | first = Braam, Piet | title = Field Guide to the Trees of Southern Africa | publisher = Struik | location = Cape Town | year = 1997 | page = 332 | isbn = 1-86825-922-6}} 3. ^1 {{cite book | last = Palgrave | first = K.C. | title = Trees of Southern Africa | publisher = Struik | location = Cape Town | year = 1984 | page = 670 | isbn = 0-86977-081-0}} 4. ^1 {{cite book | last = Pooley | first = Elsa | title = The Complete Field Guide to Trees of Natal, Zululand & Transkei | publisher = Natal Flora Publications Trust | location = Durban | year = 1997 | page = 358 | isbn = 0-620-17697-0}} 5. ^Uteroactive constituents from Combretum kraussii.
