Lobivia einsteinii MN171a

This nice form of Lobivia einsteinii was discovered, and sold  (as Rebutia) by Mats Winberg of succseed.com
Yellow flowered forms of this species were in the original discovery, also as of recently several red or orange flowered forms were entered into cultivation. This gentle salmon-flowered plant is the only form with this flower color I know as of today.

Trichicereus atacamensis ssp pasacana

This large Trichocereus plant grows in Stanford Arizona Garden. It is common species forming cactus forest in its habitat, but rarely seen in cultivation. It must be grown outside or in the large greenhouse to accommodate plant's size.
