Polaskia (named after American amateur Charles Polaski) is a genus of tree-like cacti reaching 4–5 m high, comprising 2 species. Both present primitive characteristics, but Polaskia chichipe is nearer to Myrtillocactus while Polaskia chende is nearer to Stenocereus. The genus is found in the Mexican states of Puebla and Oaxaca.[1][2]
Description
[edit | edit source]The tree-like, highly branched species of the Polaskia genus reach heights of growth of between 4 and 5 meters and form dense crowns 3 to 4 meters above the ground. Its bright green shoots repeatedly fork and grow 1 to 2 meters long. The 7 to 12 ribs are sharply triangular in cross-section. On their edges, these wear 3 to 4 millimeters wide, shield-shaped areoles at close intervals. The central spine may be absent. The 3 to 8 radial spines are greyish to blackish.
The urn- to bell-shaped flowers are white to creamy white to yellowish green. They open day and night and are between 4 and 6 centimeters long.
The red, spherical fruits with a diameter of 2 to 4 centimeters are juicy and edible. The small seeds it contains are pear- to ovoid-shaped and dull black.
