Neoporteria nidus Shrens
Echinocactus senilis Philippi, Gartenflora 35: 485. 1886. Not Beaton, 1839.
Echinocactus nidus Söhrens in Schumann, Monatsschr. Kakteenk. 10: 122. 1900.
Simple, somewhat glaucous, short-cylindric, 8 cm. long, 5 to 6 cm. in diameter, the top covered by the slender ascending connivent spines; ribs 16 to 18, obtuse, strongly tubercled; areoles large, circular; spines weak, numerous, sometimes 30 in a cluster, unequal, white, the longest 3 cm. long, bulbose at base; flowers rather slender, 4 cm. long, perhaps pinkish, but sometimes described as yellow; inner perianth-segments narrow, acute; scales on the flower-tube woolly and setose; fruit not known.
Type locality: East of Ovalle, Chile.
Distribution: Northern Chile.
Dr. Rose examined the type of E. senilis in the Philippi Herbarium in 1914 and it agrees with the first illustration cited below. He also saw a part of Mr. Söhrens's type of Echinocactus nidus at Santiago, Chile, in 1914. Its flowers were still unknown.
We have united Echinocactus senilis and E. nidus, using the later specific name since E. senilis, the older name, is a homonym. We have not seen living specimens, but we have two photographs sent us by Harvey Frank in 1905, labeled E. senilis and E. nidus, respectively, which are very much alike and led us to unite the two species. If two species are here involved, our description would apply to E. senilis.
