82 THE CACTACEAE. 
2. Ariocarpus kotschoubeyanus (Lemaire) Schumann in Engler and Prantl, Pflanzenfam. Nachtr. 
259. 1897. 
Anhalonium kotschoubeyanum Lemaire, Bull. Cercle Confér. Hort. Dép. Seine. 1842. 
‘Anhalonium sulcatum Salm-Dyck, Cact. Hort. Dyck. 1849. 5. 1850. 
Cactus kotschubeyi* Kuntze, Rev. Gen. Pl. 1: 260. 1891. 
Ariocarpus sulcatus Schumann, Monatsschr. Kakteenk. 7:9. 1897. 
Plants grayish green, 3 to 5 cm. broad, only the flat crown appearing above the surface of the 
ground, with a thickened, fleshy rootstock, and with several spindle-shaped roots from the base; 
upper part of tubercle flattened, triangular, 6 to 8 mm. long, grooved along its middle, almost to the 
tip, the groove very woolly; flowers 2.5 to 3 cm. long, originating in the center of the plant from the 
axils of the young tubercles, surrounded by a cluster of hairs; outer perianth-segments few, brownish, 
obtuse; inner perianth-segments up to 2 cm. long, oblanceolate, obtuse or apiculate, sometimes re- 
tuse, rose-colored to light purple, widely spreading; filaments, style, and stigma-lobes white; ovary 
naked; seeds oblong, 1 mm. long. ; 
Type locality: Mexico. 
Distribution: Central Mexico. 
This species was collected in Mexico and sent to Europe by Karwinsky about 1840. 
Only three specimens were sent in the first shipment, one of which sold for $200. Asa 
medium-sized plant weighs less than half an ounce, this price was somewhat in excess of 
its weight in gold! This plant was named for Prince 
Kotschoubey who was a prominent patron of horticul- 
ture. He paida thousand francs for one of these plants. 
We have not seen Lemaire’s original reference to 
Anhalonium kotschoubeyanum, but in all his subsequent 
references the name is spelled as given here. Schumann, 
however, spells the name as follows: Ariocarpus 
kotschubeyanus. 
Stromatocactus kotschoubeyi Karwinsky and Anhalo- 
nium fissipedum Monville were given by Lemaire (Illustr. 
Hort. 16: Misc. 72. 1869) as synonyms of A. kotschoubeya- 
num and by Riimpler (Férster, Handb. Cact. ed. 2. 232. 
1885) as synonyms of A. sulcatum. Ariocarpus mcdowellit 
(Haage and Schmidt, Cat. 225. 1908), unpublished, 
belongs here. Dr. Rose obtained living specimens from 
McDowell in 1906. 
Cactus kotschoubeyi Karwinsky (Hort. Univ. 6: 63. 
1845) was recorded by Lemaire while the Index Kewensis 
refers the name to Otto Kuntze (Rev. Gen. Pl. 1: 206. 1891), where the transfer is 
technically made. 
The plant, as Mammillaria sulcata, is described in the Gardeners’ Chronicle (III. 39: 
255. 1901) but no author is given and the article is unsigned. The name also occurs in 
the Index Kewensis (3: 160. 1894), credited to Salm-Dyck (Cact. Hort. Dyck. 1849. 78. 
1850), but he never used this combination. The reference of Salm-Dyck which is cited is 
to Anhalonium sulcatum.
