Catalina Mts., südliches Oracle Synonyme Echinocereus fendleri var. bonkerae Echinocereus boyce-thompsonii var. bonkerae Echinocereus fasciculatus var. bonkerae Echinocereus fasciculatus subsp. bonkerae Etymologie Echinocereus = Igelsäulenkaktus bonkerae = benannt nach Frances Bonker Originaltext der Erstbeschreibung (Auszug) It differs from all other species of its kind in that all the spines are very short, and its fruit is sweet and more nearly the size of a strawberry than any of the others; also the spines do not suggest the Hedgehog Cactus, so that the common name of Short Spined Strawberry Cactus Is given to Bonkerae, as more nearly resembling a strawberry in its fruit than any other of the Strawberry Cactus clan. The juicy, luscious berries, less than an inch long, are delicious as jam or served cold with cream; they are always the first to appear in the spring. Often but two inches tall, sometimes reaching six or eight inches, this little Strawberry Cactus …

Echinocereus bonkerae J. J. THORNBER & F. BONKER subsp. apachensis (W. BLUM & J. RUTOW) A. ZIMMERMAN Baker et al.: – Chromosome numbers of some cacti of the Western North America. – Haseltonia 15 (VII): 120 (2009) Holotypus USA, Arizona, Maricopa County, Apache Trail, near Fish Creek, Mc Kelvey 735, 18. February 1929 [US 1532949] Synonyme Echinocereus apachensis Echinocereus boyce-thompsonii Etymologie Echinocereus = Igelsäulenkaktus apachensis = benannt nach Vorkommen am Apache Trail Originaltext der Umkombination (2009) im Auszug The diploid chromosome number indicates that the well-known Fish Creek phenotype of Echinocereus is not part of the widespread tetraploid E. engelmannii. Echinocereus bonkerae ssp apachensis differs from typical E. bonkerae in spininess (mostly its spectacularly greater central spine length). Intermediate spine forms (highly variable) are seen in the Sierra Ancha (including one of the chromosome vouchers cited herein), the Mazatzal Mountains, and in the mountains between Globe and Superior. Subspecies apachensis is relatively xeromorphic (tall, seriously spiny plants at the lower altitudinal limits of the species). Nominate subspecies bonkerae grows as compact clumps of shorter stems …
