16. Cactus goodrichii (Scheer) Kuntze, Rev. Gen. Pl. 260 (1891). 
Mamillaria goodrichii Scheer in Salm Cact. Hort. Dyck. 91 (1850). 
Globose or ovate, 5 to 7.5 em. high, subsimple: tubercles ovate, short 
(3 to 5 mm.), somewhat corky and persistent, with dense wool in the 
young axils containing 5 to 8 stiff bristles: radial spines 11 to 15 (the 
uppermost one sometimes wanting), white and rigid, 5 to 7 mm. long, 
entangled with adjoining clusters; central spines 3 or 4 (often solitary 
in young plants), brownish-black, the upper ones divergent and straight 
(rarely showing a tendency to hook), the lower longer (9 to 10 mm.), 
stouter and hooked (usually upwards): flowers 12 to 18 mm. long, the 
petals yellowish-white with red midribs: fruit clavate and scarlet. (11. 
Cact. Mex. Bound. t. 8. figs. 9-14)—Type: Scheer says that the plant 
was brought from the Island of ‘Corros” (Cedros?) by Dr. Goodrich, 
and “unfortunately perished in the gardens,” which generally means 
that there is not a fragment of the type in existence. 
In dry ravines, from San Diego County, California, southward through- 
out Lower California and the neighboring islands (including Guadalupe 
Island). “ Llavina.” 
Specimens examined: CALIFORNIA (Parry of 1850, 1875; Agassiz of 
1872; Parish 450 of 1882 at Vallecito): LOWER CALIFORNIA (Gabb 18 
of 1867; Brandegee of 1889 on Magdalena Island, and 240 of 1890 from 
San Jose del Cabo): also specimens cultivated in Gard. Salm-Dyck. 
By a misprint in Cact. Mex. Bound. the specific name appeared as ‘ Goodridgii,” 
and this error appears in almost every subsequent mention of the species, even in 
Watson's Bibliographical Index, although in Syn, Cact. and other references by Dr. 
Engelinann the correct form appears. 
17. Cactus pondii (Greene). 
Mamillaria pondii Greene, Pittonia, i, 268 (1889). 
Oval or cylindrical, from low to 30 em. high, simple or sparingly 
branched: radial spines 20 to 30, white and slender; centrals 4 or 5, 
the longest over 25 mm. long, rigid and strongly hooked, dark brown 
above the middle: flowers nearly 5 em. long, bright searlet: fruit 
unknown.—Type, Pond specimens in Herb. Greene. 
Cedros Island, off the west coast of Lower California, Fl. February. 
Unfortunately, the type specimen has been mislaid, so that no examination of it 
could be made. Evidently related to C. goodrichii, but differing in its much more 
robust habit, more numerous radials, much longer spines, and larger scarlet flowers. 
1@. Cactus barbatus (Engelm.) Kuntze, Rev. Gen. Pl. 261 (1891). 
Mamitlaria barbata Engelm. Wisliz. Rep. 22 (1848). 
Depressed-globose, about 4em. in diameter, simple: tubercles 8 mm. 
long, with naked axils: radial spines very numerous (50 to 60), in two 
series, 6 to 8 mm. long, the outer (about 40) slender but rigid and white, 
the inner (10 to 15) a little stouter and yellow; usually one central 
spine, stout and erect, hooked downwards, brownish: flowers 18 to 20mm. 
long, rose-red: fruit oblong, 10 to 12 mm. long, green (when mature?)
