Pfeiffer (Abbild. Beschr. Cact. 2: pl. 10), very likely from the type collection. waese 
illustrations are not very good, especially as to the areoles. In 1845 it was again describe 
and illustrated, this time in Curtis’s Botanical Magazine, plate 4190, from a specimen sent 
by a Mr. Staines from San Luis Potosi. This is from the region of Galeotti’s type. We

rete Conous pertinals lacvior Salm-Dyck (Cact. Hort. Dyck. 1849. 43. 1850; Echinocereus 
pectinatus laevior, Monatsschr. Kakteenk. Index 56. 1912) is only aname to be referred here. 
Echinocereus pectinatus cristatus is an abnormal form of no taxonomic importance. A 
very unusual illustration of it appeared in Floralia 42: 372. This variety may or may 
not belong to this species. Echinopsis pectinata laevior Monville (Forster, Handb. Cact. 
365. 1846) belongs here.
