Mammillaria seed pods

These Mammillaria have been pollinated artificially during the winter and spring and are now producing seed pods. Some have and can be expected to flower again.

This picture shows the fruits of Mammillaria haageana ssp. schmollii (bottom of first picture). Immediately above to the right is M. formosa and to its left is M. clavidiae. Just visible in the right hand corner is a form of M. haageana found at Colonia De 

Los cruces, Puebla. On the left side is M. bocensis.

This picture shows the fleshy fruits of M. petrophila L. 052. This plant comes from Southern Baja California, Mexico.

Also visible in this picture are the dried fruits of M. elongata.







This plant comes by the tongue- twisting name of M. huitzilopochtli. There are several forms of which two can be seen in this picture. All forms of this species comes from the Tomellin Canyon of Oaxaca. The seeds were obtained from the plants discoverer, the late Dr. Alfred Lau.

Immediatly visible to the left is M. saxicola and M. sempervivi.

Yellow flowered Mamms

This dainty cactus rewards the grower with showy and lemon-scented yellow flowers. Mammillaria surculosa is reported from the Mexican states of Tamaulipas and San Luis Potosi. In the wild it forms dense mats.

In cultivation it quickly clusters in a few years. The flowers are very individual for this genus with crocus-like petals.

This and the following plant were previously placed in the genus Dolichothele due to the large tubercles and relatively large flowers. Dolicothele has been relegated to Subgenus under Mammillaria.

Mammillaria baumii is another sweetly-scented yellow-flowered charming plant. In habitat it is often found in the shade mostly on bare rocks.

It comes from the Mexican State of Tamaulipas. I have seen this species near the town of San Vicente where it forms sizable low mats.

Ortegocactus macdougallii

This interesting cactus is only found in one small area, on Cero Cantaro, at San Jose Lechuguiri, Oaxaca.

The plant is named after Francesco Ortega who first brought the plant to the famous botanist Tom MacDougall and subsequently named by Alexander in 1961.

There has been attempts to refer this plant to the Genus Coryphantha but due to its isolation it must have evolved from an early ancestor which branched into Coryphantha and Ortegocactus. Philogenetic studies conducted in 2002 places this cactus between Coryphantha and the genus Neolloydia.

I have seen this plant half buried in scree in its habitat. The area is quite inaccessible. I have had to take several lifts which took me half a day to arrive. It grows on limestone rocks. Habitat cacti can develop the same red marking as their counterparts in cultivation.

The plant is small but will eventually clump. Plants in cultivation are usually grafted but I have grown these plants on their own roots without any problem.

Small Cacti

Gymnocactus saueri was rediscovered by Friz Maurice in the 80's after being discovered by Baum and P. Sauer in 1925 and described in 1928 by Bodeker and remaining undiscovered since that time.

This Gymnocactus Saueri produced a dozen flowers.

It comes from Salamanca near san Vicente, Tamaulipas, Mexico.




Echinocereus Laui was discovered by Alfred Lau in 1974 and subsequently named for him. It comes from near El Trigo ranch, East of Yecora from the State of Sonora, Mexico.

It will eventually cluster after some time but the plant remains small.

Mammillaria painteri forma monstrosa

Mammillaria painteri fa. monstrosa is a well known form in cultivation. I have had Mammillaria bocasana cv. caterpincy. I suspect that both are the same cultivars.

Echinocereus davisii X E. pulchellus v. sharpii

This is a hybrid between Echinocereus davisii and Echinocereus pulchellus v. sharpii. Only this plant survived and it has been grafted on a pereskiopsis.
