FEROCACTUS. . 127 
The original reference to this species was very brief, as follows: ‘FE. fordii is a name 
proposed for an allied form with ashy gray spines.” The plant was later described by Mr. 
Orcutt (Rev. Cact. 2: 81. 1890) in detail and this fuller description was republished still 
later (West Amer. Sci. 13: 31. 1902). It was named for Lyman M. Ford of San Diego, 
California.

4, Ferocactus townsendianus sp. nov. 
Short-cylindric, 4 dm. high or more; ribs about 16, often spiraled, somewhat undulate; areoles 
large, distant; radial spines widely spreading, 14 to 16, 3 to 4 cm. long, most of them thread-like, 
but often 2 or more above and below, subulate; central spines subulate, grayish, usually one curved 
or hooked at apex, the others straight, all annulate; flowers large, 5 to 6 cm. long; outer perianth- 
segments ovate, reddish, with narrow yellow margins; inner perianth-segments oblong-lanceolate 
with a narrow pink stripe down the center with greenish-yellow margins; filaments and style dark 
pink; stigma-lobes pale greenish brown. 
Collected by J. N. Rose on San Josef Island, Gulf of California, March 15, 1911 (No. 
16570). 
This species is common near the coast, growing chiefly on the dry mesa along with 
desert shrubs. 
This species is named for Dr. Charles H. Townsend, Director of the New York Aqua- 
rium, who was in charge of the scientific work of the Albatross during the cruise into Lower 
California waters in 1911, when this plant was discovered. 
Plate xu, figure 1, shows the flowering type-plant sent by Dr. Rose to the New York 
Botanical Garden in 1911, where it immediately bloomed. Figure 133 1s from a photo- 
graph of the same plant. 
5. Ferocactus chrysacanthus (Orcutt). 
Echinocactus chrysacanthus Orcutt, Rev. Cact. 1: 56. 1899. 
Globose to cylindric; ribs about 18, tubercled; radial spines 4 to many, slender, white; central 
spines sometimes as many as 10, 5 cm. long, either red or yellow, curved; flowers from near the center 
of the plant, 5 cm. broad when fully open; scales naked in the axils, closely set and overlapping, the 
lower one orbicular and green, the upper ones more oval, brownish or with brown tips, the margin 
thin, sometimes ciliate or ragged; outer perianth-segments rather stiff, pinkish brown, inner perianth- 
segments 2 cm. long, satiny yellow with a jagged or toothed margin, fruit yellow, 3 cm. long, seeds 
large, black. 
Type locality: Cedros Island, Lower California. 
Distribution: Only on Cedros Island, and the adjacent coast of Lower Califorma. 
This plant is common on Cedros Island in the broad dry valleys which run back from 
the coast. It was re-collected by Dr. Rose at the type locality, in I9IT. Dr. Rose 
obtained plants on Cedros Island about 2 dm. high, but we presume the plant becomes 
much larger. . 
According to C. R. Orcutt, “E. rubrispinus (Rev. Cact. 1: 56. 1899) is a name pro- 
posed by L. M. Ford for the red-spined form and so distributed” ; otherwise we know noth- 
ing of it. och | 
Echinocactus emoryi chrysacanthus (Schumann, Gesamtb. Kakteen Nachtr. 99. 1903 
is a garden name and so far as we are aware is not published.
