Echinopsis maximiliana, synonym Lobivia maximiliana, is a species of Echinopsis found in Bolivia and Peru.[3][4]
Description
Echinopsis maximiliana usually forms small cushions. The spherical to short cylindrical, green shoots reach a diameter of 5 centimeters and a height of up to 20 centimeters. There are twelve to 20 straight ribs that are notched and tuberous. The areoles on them are whitish and are up to 2 centimeters apart. The four to twelve thorns that arise from them, which can rarely be missing, are very variable. As a rule, they cannot be differentiated into central and peripheral spines. The unequal, curved spines are brownish to yellowish and 3 to 5 centimeters long.
The short to long tube-funnel-shaped flowers appear laterally on the upper parts of the shoots. They are red with an orange-yellow throat, or sometimes yellow or pink to purple. The flowers are 4 to 10 centimeters long and have the same diameter. The reddish green fruits are hairy and reach a diameter of up to 1.2 centimeters[5]
Taxonomy
The first description as Echinopsis maximiliana by Albert Gottfried Dietrich was published in 1846, with the name attributed to Edward Heyder.[2][6] The specific epithet maximiliana honors a friend of Heyder's who died too early named Maximilian. The species was transferred to the genus Lobivia in 1975. As of November 2025[update], Plants of the World Online accepted the earlier placement in Echinopsis.[3]
Subspecies
As of November 2025[update], Plants of the World Online accepted three subspecies:[3]
- Echinopsis maximiliana subsp. caespitosa (J.A.Purpus) M.Lowry
- Echinopsis maximiliana subsp. maximiliana
- Echinopsis maximiliana subsp. westii (Hutchison) M.Lowry
