Brosimum utile(Kunth), also called Galactodendron, Pittier (= B. galactodendron) [1] is a plant species in the family Moraceae.
Brosimum utile can grow to a height of 30m. [2] It is monoecious and has bisexual inflorescences.
In 1799, the renowned German polymath Alexander von Humboldt, accompanied by French botanist Aimé Bonpland, embarked on a five-year trip to South America. On one occasion, in January 1800, they traveled 130 miles, climbing the Silla de Caracas mountain near Caracas, Venezuela, passed through the valleys of Aragua and Tui, visited the mountains of Los Tequos, the hot springs of Mariare and Trinchera, and the northern shore of the lake of Valencia (by the town of Valencia, Venezuela), where they made the discovery of the cow-tree, so called from its yielding milk. They continued through New Valencia and over the mountain range of Higuerote to Puerto Cabello, 20 miles north of Valencia. [3]
By February 1801 they had reached Havana, Cuba. Humboldt took the precaution of making two copies of their descriptions of plants, consisting of two volumes, and containing 1,400 specimens. One copy went to France to be retrieved for Bonpland and one to London through John Fraser to the German botanist Carl Ludwig Willdenow, Humboldt's friend and early instructor. Willdenow started work on the project, but his premature death required Humboldt to pass on this immense challenge to Carl Sigismund Kunth who completed the work. Bonpland never completed his assignments for this task.
The number of plants actually described during the five-year journey amounted to 4,528, and the descriptions filled six volumes three folios and three quartos. The localities of all these plants, as described in the 'Nova Genera et Species Plantarum in Peregrinatione ad Plagam Aequinoctialem Collectarum,' [4] are denoted with the barometric determination of the height above the sea, a detail which has never before been introduced into any botanical work.
These volumes were employed by the celebrated German botanist Carl Sigismund Kunth, Director of the Botanic Gardens at Berlin, in editing at Paris the 'Nova Genera et Species.' As only about a fifth of these descriptions are from the pen of Alexander von Humboldt, the volumes on the death of Professor Kunth were sent by Humboldt, in acknowledgment of the indefatigable industry of his fellow traveller, to the Museum of Natural History at Paris, where they were preserved as the property of Bonpland. [5]
In tracking the priority for the discovery and reporting of the cow-tree, it is documented that Brosimum utile (Kunth) Oken was published in: Allgemeine Naturgeschichte fur alle Stande. Register. 3(3): 1571 (1841) [6] [7]
It took 41 years from when Humboldt discovered this tree and wrote about it in letters from South America to friends in Europe (although known to the Native Americans), to when Kunth was able to compile and definitely publish this and other findings.
Of interest was that as early as 1818, Humboldt's discovery was mentioned in a North American magazine. "American Monthly Magazine and Critical Review" (New York) 4 1818: 309 Cow tree. {Description is based on the reports of Humboldt and Franz Bredemeyer} [8] [9]
The range of Brosimum utile, a shade-tolerant species native to southern Central America and northern South America, extends from Brazil and Venezuela to Costa Rica, where it is numerous in the tropical wet forests of Piedras Blancas National Park. This climax-species dominates canopies on well-drained slopes, in addition to thriving in the mountain and upland forests of the Golfo Dulce region.
The tree can be found in the rainforest of Golfo Dulce Retreat, where typical features of this species may be observed, including buttresses from which Brosimum utile's classic white latex may be extracted. Brosimum utile is also cultivated in India, Sri Lanka and Indonesia. [2]
Propagation is from seed or from cuttings. [2]
The white latex of Brosimum utile is valued for its pharmacological properties and is historically used as a milk substitute by indigenous Central and South Americans. The milk, which contains 5 to 7% protein, can be used for cheese, ice cream, and other products. Taste varies between trees. Some brosmium utile trees have sweet latex, while others are bitter. [10]
The latex of Brosimum utile yields a wax called galactin, which can be used in candles. [11]
The fibrous bark can be used to make cloth, sails, or blankets. [10]
The wood of Brosimum utile is sometimes called Sande and is used for plywood, particleboard, fiberboard, carpentry, light construction, furniture components, and moulding. [12]
The leaves and branch tips can serve as cattle fodder. The edible nuts and fruits can be eaten boiled or salted, and can also be used for pig feed. [2] [10]
Friedrich Wilhelm Heinrich Alexander von Humboldt was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern geomagnetic and meteorological monitoring.
Aimé Jacques Alexandre Bonpland was a French explorer and botanist who traveled with Alexander von Humboldt in Latin America from 1799 to 1804. He co-authored volumes of the scientific results of their expedition.
Michel Félix Dunal was a French botanist. He was a professor of botany in Montpellier, France.
Carl Sigismund Kunth was a German botanist. He was also known as Karl Sigismund Kunth or anglicized as Charles Sigismund Kunth. He was one of the early systematic botanists who focused on studying the plants of the Americas. Kunth's notable contributions include the publication of Nova genera et species plantarum quas in peregrinatione ad plagam aequinoctialem orbis novi collegerunt Bonpland et Humboldt. This work spanned seven volumes and was published between 1815 and 1825.
Carl Ludwig Willdenow was a German botanist, pharmacist, and plant taxonomist. He is considered one of the founders of phytogeography, the study of the geographic distribution of plants. Willdenow was also a mentor of Alexander von Humboldt, one of the earliest and best known phytogeographers. He also influenced Christian Konrad Sprengel, who pioneered the study of plant pollination and floral biology.
Cow tree can refer to:
Pinguicula moranensis is a perennial rosette-forming insectivorous herb in the flowering plant family Lentibulariaceae. It is native to El Salvador, Guatemala, Honduras and Mexico. A species of butterwort, it forms summer rosettes of flat, succulent leaves up to 10 centimeters (4 in) long, which are covered in mucilaginous (sticky) glands that attract, trap, and digest arthropod prey. Nutrients derived from the prey are used to supplement the nutrient-poor substrate that the plant grows in. In the winter the plant forms a non-carnivorous rosette of small, fleshy leaves that conserves energy while food and moisture supplies are low. Single pink, purple, or violet flowers appear twice a year on upright stalks up to 25 centimeters long.
Brosimum is a genus of plants in the family Moraceae, native to tropical regions of the Americas.

Species in the genus can be readily distinguished from related genera by their distinctive downward-pointing spines on the stem, which are actually modified roots. They are known as the "root spine palms".
