''Croton'' comprises about 1200 species and occurs throughout the warmer parts of the world. It is best represented in the Americas; about 65 species occur in continental Africa and about 125 in Madagascar.
The wood of several other ''Croton'' species is used in tropical Africa, but none of them is important.  === ''Croton penduliflorus'' ===In Ghana the wood of ''[[Croton penduliflorus]]'' Hutch., a small to medium-sized tree up to 20 m tall, is used for rafters. === ''Croton longiracemosus'' ===In DR Congo the wood of ''[[Croton longiracemosus]]'' Hutch., a medium-sized tree up to 30 m tall with bole up to 40 cm in diameter, is used for construction, whereas in Congo the leaves are eaten as a tonic and applied to maturate furuncles.
In DR Congo the wood of === ''Croton longiracemosuswellensii'' Hutch., a medium-sized tree up to 30 m tall with bole up to 40 cm in diameter, is used for construction, whereas in Congo the leaves are eaten as a tonic and applied to maturate furuncles. ===In Gabon the whitish wood of ''[[Croton wellensii]]'' De Wild., a medium-sized tree up to 25(–30) m tall with bole up to 45(–80) cm in diameter, is used for stools.
=== ''Croton dichogamus'' ===In Kenya the wood of ''[[Croton dichogamus]]'' Pax, a shrub or small tree up to 7.5 m tall, is used in building huts. The roots and stems are used to flavour food and drinks. Roots and sometimes leaves are used in traditional medicine to treat colds, fever, tuberculosis and syphilis, and as a tonic.
=== ''Croton megalobotrys'' ===In southern Africa the whitish wood of ''[[Croton megalobotrys]]'' Müll.Arg., a small tree up to 15 m tall with bole up to 60 cm in diameter, is considered useful for unspecified purposes. The bark and seeds have some reputation as a treatment for malaria, whereas roots and bark are used as purgative and to treat ascites and female sterility. Leaves are used to treat body pain and seeds as vermifuge.
== Anatomy ==
Wood-anatomical description (IAWA hardwood codes):
*Growth rings: 1: growth ring boundaries distinct. *Vessels: 5: wood diffuse-porous; (10: vessels in radial multiples of 4 or more common); 13: simple perforation plates; 22: intervessel pits alternate; (23: shape of alternate pits polygonal); 27: intervessel pits large (<font size="1">≥</font> 0 μm); 30: vessel-ray pits with distinct borders; similar to intervessel pits in size and shape throughout the ray cell; 42: mean tangential diameter of vessel lumina 100–200 μm; 47: 5–20 vessels per square millimetre; 58: gums and other deposits in heartwood vessels. *Tracheids and fibres: 61: fibres with simple to minutely bordered pits; 66: non-septate fibres present; 69: fibres thin- to thick-walled. *Axial parenchyma: 76: axial parenchyma diffuse; 77: axial parenchyma diffuse- in-aggregates; 78: axial parenchyma scanty paratracheal; 86: axial parenchyma in narrow bands or lines up to three cells wide; 92: four (3–4) cells per parenchyma strand; 93: eight (5–8) cells per parenchyma strand. *Rays: 97: ray width 1–3 cells; 104: all ray cells procumbent; (113: disjunctive ray parenchyma cell walls present); 115: 4–12 rays per mm. *Mineral inclusions: 136: prismatic crystals present; 138: prismatic crystals in procumbent ray cells; (139: prismatic crystals in radial alignment in procumbent ray cells).
