Often growing in colonies 2 to 5 meters broad; stems cylindric, much branched, usually less than 

 I meter high, but occasionally 1.5 meters high, with numerous lateral branches; branches rather 

 short, usually only 8 to 20 cm. long, thick (5 to 6 cm. in diameter); old branches bluish green, with 

 low tubercles sometimes 2 cm. long; young joints bright green, with high tubercles flattened laterally; 

 spines tardily developing, but formidable on old branches, very unequal, in clusters of 10 or more, 

 the longest ones nearly 10 cm. long, whitish in age; glochids numerous, brownish, caducous; leaves 

 minute, 2 to 3 mm. long; areoles circular, when young filled with white wool, in age somewhat ele- 

 vated on the areoles ; flowers rather variable in length, 4 to 8 cm. long including the ovary, rose- 

 colored to nearly white; petals broad, apiculate, 2 to 2.5 cm. long; filaments rose-colored; ovary 

 strongly tuberculate ; areoles filled with numerous brown glochids and subtended by minute leaves ; 

 style white ; stigma-lobes green ; fruit ovoid to oblong in outline, nearly white ; umbilicus truncate ; 

 seeds small, 4 mm. broad.

Opuntia geissei according to a statement made to Dr. Rose by Juan Sohrens, of San- 

 tiago, IS the same as O. miquelii, and this the former was able to verify by later herbarium 

 and field studies.

Opuntia rosiflora Schumann was based on PhiHppi's unpubHshed name 



made

This 



Dr 



also obtained from WiUiam Geisse a part of PhiHppi's original specimen, which came, .. .„- 

 label states from near Bandurrias, in the valley of Carrizal, in the Province of Atacama. 

 Later on, while making field observations in Atacama, Dr. Rose found this species very com- 

 mon from north of Castillo to Vallenar. This is in the general region of geissei (O rosea 

 and 0. rostflora) and m the river valley of the Huasco. Huasco. the type locality of 

 O. miquelu, IS 25 miles lower down this valley, and we have no hesitancy in uniting them all.
