Synonyms:

This is actually a synonym of Mammillaria longimamma f. cristata. Other synonyms are Cactus longimamma f. cristata and Neomammillaria longimamma f. cristata.

Habitat:

Dolichothele longimamma f. cristata is a nursery cultivar and, thus, doesn’t exist in nature. Mammillarias, in general, are native to America: in particular Mexico, Souther U.S.A., Central America and Caribbean.

Description:

Dolichothele longimamma f. cristata is a captivating cactus distinguished by its unique crested form, featuring long, soft, and fresh green tubercles. The robust stem of this crested variant stands out with an impressive thickness, measuring between 8 to 10 centimeters and forming a substantial, convoluted mound as it matures. Crested varieties are the result of a genetic mutation of stem cells that change the dinamics of cellular reproduction, so that new cells are produced only in two perpendicular directions and the resulting organs are flattened, fan-shaped and finally curling into brain-shaped structures. While crested Dolichothele longimamma is a rarity, this phenomenon naturally occurs and can be observed in various other cactus species. Characterized by 8 to 10 spines of similar thin, needle-like appearance, ranging in color from yellow to amber, this Dolichothele longimamma f. cristata includes a central spine that extends up to 25 millimeters, adding to its distinctive features. During its blooming season from May to July, this cactus showcases exceptionally large flowers, with petals spanning 4-6 centimeters in length and 4.5-6 centimeters in width, displaying a vibrant yellow hue.

Cultivation:

Cultivating and propagating Dolichothele longimamma f. cristata is a rewarding endeavor, especially when considering the distinctive brain-like mounds that develop as the plant matures. Grafted specimens of this unique cactus are known for their ease of growth. Over time, they form impressive, expansive mounds with a distinctive appearance resembling a complex neural network.
During the active growing season in spring and summer, adequate watering is crucial to encourage steady growth and prevent the large tubercles from becoming flabby. It is important to find a balance, ensuring sufficient moisture without overwatering, as Dolichothele longimamma f. cristata, like many thick-rooted species, is sensitive to rot.
For plants grown on their own roots, a deep pot with a well-draining mineral substrate is recommended. The tuberose roots of Dolichothele longimamma f. cristata thrive in this environment. Careful attention to watering is paramount, as these species with thick roots are prone to rot if overwatered. During the winter rest period, it is advisable to keep the plant dry, as it may naturally pull near the surface of the potting mix.
In essence, successful cultivation of Dolichothele longimamma f. cristata involves understanding its unique growth patterns, providing appropriate watering measures, and appreciating the stunning brain-like formations that make this cactus a fascinating addition to any succulent collection.

Propagation:

Being a crested cultivar, the only possible propagation technique is grafting on stronger varieties or either by cuttings, that have to be replanted into a well-drained substrate, in a protected, humid space, at a temperature around 20ºC.

Curiosity:

The etymology of the genus name “Dolichothele” can be broken down into two components. The first part, “Dolicho,” is derived from the Greek word “dolichos,” meaning “long” or “extended.” The second part, “thele,” is also of Greek origin, meaning “nipple” or “teat.”
Therefore, the name “Dolichothele” suggests a connection to long or extended nipples, likely referencing the characteristic shape or structure of the cactus. This naming convention reflects the attention given to specific morphological features or growth patterns of the plants within this genus.
