The bark is black to brown, corrugated or fissured, and scaly, fissuring in a characteristic rectangular pattern. The [[leaf|leaves]] are alternate, simple, {{convert|8-20|cm|abbr=on}} long, elliptical, bluntly or acutely pointed, [[glabrousness (botany)|glabrous]], and dark green above, pale green below, with mildly serrated margins.

It grows in bunches ripening September through November, several months after pollination.&lt;br /&gt;

In addition to its value for its timber and its medicinal uses, &amp;#039;&amp;#039;Prunus africana&amp;#039;&amp;#039; is an important food source for frugivorous birds and mammals.

Large numbers of trees are harvested for its bark to meet the international demand for its medicinal qualities. Early studies on the effects of bark harvest showed that the harvest affected population structure, increased mortality and decreased fecundity (Parrott and Parrott, 1989;&amp;lt;ref&amp;gt;Parrott J., Parrott, H., 1989. Report on the conservation of &amp;#039;&amp;#039;Prunus&amp;#039;&amp;#039; (&amp;#039;&amp;#039;Pygeum africanum&amp;#039;&amp;#039;) in Cameroon.

Zahemena et au Département de l’Eau and des Forêts, Antannarivo, Madagascar.&amp;lt;/ref&amp;gt;). However, quantitative studies to examine specific life history parameters and possible sustainable harvesting practices were begun only recently (Stewart, 2001&amp;lt;ref&amp;gt;Stewart, K.M., 2001. The commercial bark harvest of &amp;#039;&amp;#039;Prunus africana&amp;#039;&amp;#039; on Mount Oku, Cameroon: effects on traditional uses and population dynamics. Ph.D. Dissertation, Florida International University.&amp;lt;/ref&amp;gt; and 2009&amp;lt;ref&amp;gt;{{Cite journal|last=Stewart|first= K.

In these later studies, the combined factors of mortalities of a large percentage of reproductive trees (especially the largest ones), highly reduced fruit production and poor seedling survival seem to suggest a bleak prognosis for future regeneration and long-term persistence of the species in harvested populations.&lt;br /&gt;

The timber is a hardwood employed in the manufacture of axe and hoe handles, utensils, wagons, floors, chopping blocks, carving, bridge decks, and furniture. The wood is tough, heavy, straight-grained, and pink, with a pungent bitter-almond smell when first cut, turning mahogany and odorless later.&amp;lt;ref name=who/&amp;gt;&amp;lt;ref name=&amp;quot;:1&amp;quot; /&amp;gt;&lt;br /&gt;

==Conservation status==&lt;br /&gt;
The collection of mature bark for its use in traditional medicine and other uses has resulted in the species becoming endangered.&amp;lt;ref name=&amp;quot;iucn status 11 November 2021&amp;quot; /&amp;gt;&amp;lt;ref&amp;gt;{{Cite news | url = http://www.voanews.com/english/news/a-13-2006-05-22-voa24.html | newspaper = VOANews | date = 22 May 2006 | access-date = 20 January 2011 | title = Africa&amp;#039;s Medicine Tree Facing Extinction From Greed, Corruption}}&amp;lt;/ref&amp;gt;  &amp;#039;&amp;#039;P. africana&amp;#039;&amp;#039; continues to be taken from the wild.

==Discovery and classification==&lt;br /&gt;
The name of the remedy, pygeum, comes from the name of the plant, which was discovered to botany by [[Gustav Mann]] during his now-famous first European exploration of the [[Cameroon line|Cameroon Range]], with [[Richard Francis Burton]] and [[Alfred Saker]], in 1861. A letter from Mann to the [[Linnean Society of London]], read by [[William Jackson Hooker]], then Director of the [[Royal Botanic Gardens, Kew]], on June 5, 1862, describes the naming of the peaks of the Cameroon Range (such as Mount Victoria, later Mount Cameroon&amp;lt;ref&amp;gt;The British names did not survive the transfer of Cameroon to Germany in 1884 and now are nearly unknown.&amp;lt;/ref&amp;gt;) and the collection of specimens there.&amp;lt;ref&amp;gt;{{cite journal | last=Hooker | first=Sir W.J. | author-link=William Jackson Hooker | title=Letter from Mr. G. Mann, Government Botanist, describing his Expedition to the Cameroon Mountains | journal=Botanical Journal of the Linnean Society | volume=VII | pages=1–13 | year=1864 | issue=25 | url=http://www.botanicus.org/page/166680 | doi=10.1111/j.1095-8312.1863.tb01054.x }}&amp;lt;/ref&amp;gt; The latter were shipped back to Kew for classification, which was duly performed by Hooker and his son, [[Joseph Dalton Hooker]], who had the responsibility of publishing them, as William died in 1865.&lt;br /&gt;
&lt;br /&gt;
When the publication came out&amp;lt;ref&amp;gt;{{cite journal | last=Hooker | first=J.D. | author-link=Joseph Dalton Hooker | title=On the Plants of the Temperate Regions of the Cameroons Mountains and Islands in the Bight of Benin; collected by Mr. Gustav Mann, Government Botanist | journal=Botanical Journal of the Linnean Society | volume=VII | pages=191–192 | year=1864 | issue=28 | url=http://www.botanicus.org/page/166680 | doi=10.1111/j.1095-8312.1864.tb01067c.x}} The article occupies pages 171–240. The botanical abbreviation for this publication is J. Proc. Linn. Soc., Bot.&amp;lt;/ref&amp;gt; the Hookers had named the plant &amp;#039;&amp;#039;Pygeum africanum&amp;#039;&amp;#039;, followed by the designation &amp;quot;n. sp.&amp;quot;, an abbreviation for &amp;#039;&amp;#039;nova species&amp;#039;&amp;#039;. The habitat is listed as &amp;quot;Cameroons Mountains, alt. 7000-7500 feet&amp;quot;, which was above the tropical forest and in the alpine grasslands. Hooker notes that another specimen had been &amp;quot;gathered in tropical Eastern Africa&amp;quot; at 3000 feet by Dr. Kirk on an expedition of [[David Livingstone]].&lt;br /&gt;
&lt;br /&gt;
The first publication of the synonym in 1864 had been preceded by publication of the bare name in 1863 in a book by [[Richard Francis Burton]].&amp;lt;ref&amp;gt;{{Cite book | first=J.D. | last=Hooker | author-link=Joseph Dalton Hooker | contribution=Enumeration of the Mountain Flowering Plants and Ferns Collected by M.

Proc. Linn. Soc., Bot. 7 for 1864 available to some, as Burton mentions the volume and Mann&amp;#039;s letter in 1863.&amp;lt;ref&amp;gt;Page 47, first note.&amp;lt;/ref&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Hooker gives scant hint of why he chose &amp;quot;pygeum&amp;quot;; however, what he does say indicates it was common knowledge among botanists. Kirk&amp;#039;s specimen fruit was &amp;quot;a much depressed sphere&amp;quot;. By this, he undoubtedly meant to reference [[Joseph Gaertner]]&amp;#039;s genus, &amp;#039;&amp;#039;Pygeum&amp;#039;&amp;#039; Gaertn.,&amp;lt;ref&amp;gt;{{cite web | title=Pygeum Gaertn. | work=Germplasm Resources Information Network (GRIN) Taxonomy for Plants | author=U.

&lt;br /&gt;
In 1965, [[Cornelis Kalkman]] moved &amp;#039;&amp;#039;Pygeum&amp;#039;&amp;#039; to &amp;#039;&amp;#039;Prunus&amp;#039;&amp;#039;, and this classification has the authority for now.&amp;lt;ref&amp;gt;{{cite journal | first=Cornelis | last=Kalkman | author-link=Cornelis Kalkman | title=The Old World Species of &amp;#039;&amp;#039;Prunus&amp;#039;&amp;#039; subg.

==Names==&lt;br /&gt;
&amp;#039;&amp;#039;Prunus africana&amp;#039;&amp;#039; is known by the common names African cherry, pygeum (from its former scientific name, &amp;#039;&amp;#039;Pygeum africanum&amp;#039;&amp;#039;), iron wood, red stinkwood, African plum, African prune, and bitter almond. In other languages spoken where it grows, it is known as {{transl|am|tikur inchet}} in [[Amharic]], {{transl|mis|mkonde-konde}} in [[Chaga language|Chagga]], {{transl|ki|[[wikt:mũiri|muiri]]}} in [[Gikuyu language|Kikuyu]], {{transl|lg|entasesa}} or {{transl|lg|ngwabuzito}} in [[Luganda|Ganda]], {{transl|xh|uMkakase}} in [[Xhosa language|Xhosa]], {{transl|zu|inyazangoma-elimnyama}} or {{transl|zu|umdumezulu}} in [[Zulu language|Zulu]], {{transl|niq|tendwet}} in [[Naandi language|Nandi (Kalenjin)]] and {{lang|af|rooi-stinkhout}} in [[Afrikaans]].&amp;lt;ref name=&amp;quot;dwaf&amp;quot;/&amp;gt;&lt;br /&gt;
