Cerritos, San Luis Potosi

Mexico-Nuevo Leon, 100-200m., in very restricted area.

This newly described species (in 2003) was in the new genus Digitostigma, a monotypic one, but later it was lumped into the genus Astrophytum.

It seems not too difficult to cultivate, but we have not enough experience nowadays. So, it is best to keep it grafted. By the way, it is still very expensive in the cactophiles world.

Specimen at San Diego Botanic Garden, formerly Quail Botanical Gardens.

Astrophytum myriostigma

Cerritos, San Luis Potosi

With Voigtlander APO-Lanthar 90/3.5 at f/3.5.

Lugar de origen: México, región montañosa del centro.

Descripción: La especie, conocida popularmente como birrete de obispo, es de tallo globular, deprimido en el apice, mide entre 10 y 25 cm. de diametro y puede presentarse un tanto columnar cuando el ejemplar es adulto. Es de color verde aunque esta cubierto de manera abundante por escamosidades blancas muy pequeñas que le confieren un aspecto blanco grisaceo. Las costillas habitualmente son cinco, aunque también existen formas de 4 a 8 costillas, muy prominentes y agudas. Las aréolas son muy pequeñas y estan muy juntas. Son completamente inermes y estan cubiertas generalmente de pelos parduscos. Las flores miden alrededor de 6 cm. de diametro y son de color amarillo. Existen diversas variedades entre ellas, quadricostatum, con sólo 4 costillas y nudum, de tallo color verde, sin restos de escamas.

Consejos de cultivo: La planta no produce vastagos, por lo que la multiplicación debe realizarse a través de semillas, aunque si se corta la parte superior de los ejemplares de mayor edad, los nuevos retoños aparecen en el tallo. Requiere exposición a pleno sol y sustrato poroso.

EDAD 2.5 AÑOS

This was part of the private collection of cacti and succulents at Manor Nursery, Angmering, West Sussex. The collection was started in 1948. The nursery is now gone. The collection has been dispersed to various new locations.

Astrophytum is a genus of six species of cacti, native to North America.

These species are sometimes referred to as living rocks, though the term is also used for other genera, particularly Lithops (Aizoaceae). The generic name is derived from the Greek words άστρον (astron), meaning "star," and φυτόν (phyton), meaning "plant."
