THE CACTACEAE. 



2. Ariocarpus kotschoubeyanus (Lemaire) Schumann in Engler and Prantl, Pflanzenfam. Nachtr. 

 259. 1897. 



Anhalonium kotsclwubeyanum Lemaire, Bull. Cercle Confer. Hort. Dep. Seine. 1842. 

 Anhalonium sulcatum Salm-Dyck, Cact. Hort. Dyck. 1849. 5. 1850. 

 Cactus kotschubeyi* Kuntze, Rev. Gen. PI. 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. As a 

 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 paid a 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 

 kotschubcyanus. 



Stromatocactus kotschoubeyi Karwinsky and Anhalo- 

 nium fissi pedum Monville were given by Lemaire (Illustr. 

 Hort. 16: Misc. 72. 1869) as synonyms of .4. kotschoubeya- 

 num and by Rumpler (Forster, Handb. Cact. ed. 2. 232. 

 1 885) as synonyms of .4 . sulcatum. Ariocarpus mcdowcllii 

 (Haage and Schmidt, Cat. 225. 1908), unpublished, 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. PI. 1: 206. 1891), where the transfer is 

 technically made. 



The plant, as Mammillaria sulcata, is described in the Gardeners' Chronicle (III. 30: 

 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.
