THE CACTACEAE. 
Pfeiffer (Abbild. Beschr. Cact. 2: pi. 10), very likely from the type collection. These 
illustrations are not very good, especially as to the areoles. In 1845 it was again described 
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 
refer here Lloyd’s No. 4 from Zacatecas. 
Cereus pectinatus laevior Salm-Dyck (Cact. Hort. Dyck. 1849. 43. 1850; Echinocereus 
pectinatus laevior, Monatsschr. Kakteenk. Index 56. 1912) is only a name 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.

cited above. 
38 . Echinocereus fitchii sp. nov. 
Plants short-cylindric or somewhat narrowed above, 
8 to 10 cm. long, 4 to 5 cm. in diameter; ribs 10 to 12, 
low, rounded; areoles 4 to 6 mm. apart, small, circular; 
radial spines about 20, white, spreading, 4 to 6 mm. 
long; central spines 4 to 6, slightly spreading, 12 mm. 
long or less, acicular, brownish, but sometimes white at 
base; flowers 6 to 7 cm. long, pink; perianth-segments, 
oblanceolate, widely spreading, acute, serrate on the 
margin; ovary 2.5 cm. long, bearing numerous areoles, 
these spiny and with cobwebby hairs. 
Living specimens were collected by Dr. Rose 
near Laredo, Texas, in 1913 (No. 18037) which flowered in the New York Botanical Garden, 
April 10, 1914. 
This plant is named for Mr. William R. Fitch who accompanied Dr. Rose on collecting 
trips to the West Indies and to western Texas in 1913. 
Plate hi, figure 2, is of the type plant cited above. 
39 . Echinocereus scopulorum sp. nov. 
Stems single, cylindric, 10 to 40 cm. long, nearly hidden by the closely set spines; ribs 13 or more, 
low, somew r hat tuberculate; areoles circular, devoid of wool (at least in areoles of the previous year); 
spines highly colored, pinkish or browmish with blackish tips, in age, hov T ever, gray and stouter; 
radials somewhat spreading; centrals 3 to 6, similar to the radials; flower-buds or some of them 
appearing near the top of the plant, developing very slowly; flowers with a delicate rose perfume, 
widely spreading when fully expanded, 9 cm. broad; tube 2 cm. long, broadly funnelform, bearing 
greenish tubercles; inner perianth-segments 4 cm. long, rose or purplish rose in color, much paler on 
the outside, sometimes nearly wdiite, rather loose and usually only in about 2 rows, oblanceolate to 
spatulate, erosely dentate, acute; stamens greenish; style stout, much longer than the stamens; 
stigma-lobes linear, 12.
