Description: Lobivia famatimensis var. jachalensisSN|15822]]SN|15822]] is one of the geographical form of Lobivia famatimensisSN|3315]]SN|3315]] (Referred to Echinopsis by Friedrich & Rowley). It is hardly distinguished from the type species, but has paler creamy white radial spines flattened against the body and pectianted (centrals absent). However the distinguishing characteristics of var. jachalensis, appear to fall within the natural variation of Lobivia famatimensisSN|3315]]SN|3315]] and the names Lobivia famatimensis var. jachalensisSN|15822]]SN|15822]] is not accepted by many botanists that treat it as synonym, but it still has a value for a collector because they identify plants with particular characters.
Derivation of varietal name: “jachalensis” For Jachal, San Juan, Argentina.

Cultivation and Propagation: Very slow growing. The Lobivia famatimensisSN|3315]]SN|3315]] have a thick taproot and are susceptible to over-watering. Sometimes they are grafted to avoid root rot problems. Suited for sunny-bright exposure; they can tolerate light shade. They like warmth (recommended minimum winter temperature 5° C). But plant kept perfectly dry can easily survive in winter night temperatures below 0° C. They prefer airy exposures. Water regularly in summer, but do not overwater, it prefer a completely dry place during winter. Suited for sunny-brightly exposure; can tolerate light shade.
Pests & diseases: It is especially prone to rot, therefore, underpot in a smaller but deep pot filled with a highly gritty compost and much drainage, to accommodate its tap root.
Propagation: Seeds or graft. Seedlings of the var. bonnieae grow faster than other Lobivia famatimensisSN|3315]]SN|3315]]. Seeds can be sown in the spring or summer. The seedlings should not be disturbed until they are well rooted, after which they can be planted separately in small pots.
