Paz�察�Palmer 880 of 1890�察�on Carmen Island�察�Brandegee 241 of 1890�察�at 

Rancho Colorado��。 

     One of the most showy species of Lower California。The plant has the 

appearance   of   a   Coryphanth�察  �and   is   remarkable   for   its   tall   and   slender 

habit�察�its large central hooks�察�and its globose fruit。Since 1867 this species 

has been in Herb。 Engelmann�察�fully characterized as above under the very 

appropriate specific name longihamatus。

San Borgia�察�Brandegee of 1889�察�from San Borgia and San Julio Canyon��。 

     In his notes Mr。 Gabb describes the flower as ;large�察�3 to 3。5 inches 

long�察�bell´shaped�察�of a beautiful purplish red color�察─�concerning which Dr。 

Engelmann remarks ;this would indicate a Coryphanth�察�but the tubercles 

show no trace of a groove�察�and�察�moreover�察�a withered remnant of a flower 

laterally attached ��say 18 to 20 mm。 long���察�so that I have no doubt that Mr。 

Gabb's   statement   is   founded   on   some   error。;It   is   very   probable   that   the 

flowers are scarlet and larger than Dr。 Engelmann suggests。The species is 

closely allied to C。 roseanus�察�but differs in its shorter tubercles and much 

longer   spines。About   a   dozen   stems   rise   in   a   clump�察  �about   a   foot   high�察�

covering an area of 2 or 3 feet。These two species represent a very distinct 

Lower   Californian   group   of   cylindrical   and   hooked   Eumamillarias。Both 

probably have   showy  scarlet flowers   and   may attain   considerable length 

when growing upon rock ledges so as to become pendent。The specimens 

of C。 setispinus from San Julio Canyon are from younger parts and show 

but   a   single   long   and   hooked   central。The   San   Borgia   specimens   show 

mostly 3 or 4 centrals�察�the lowest one hooked and becoming remarkably 

long and often variously twisted and curved。However�察�I can discover no 

difference except such as may be due to age。

     The    tubercles    are  so   close   together   that   the  plant   appears    thickly 

covered with the unusually stout and erect´spreading straight spines�察�a few

     There     is  a  confusion     of  synonymy       between     this  species    and   C。 

rhodanthus�察�both having been named Mamillaria lanifera。 The earlier M。 

lanifera of Haworth�察�however�察�is clearly M。 rhodantha of Link & Otto�察�and 

although Prince Salm´Dyck revived the name for the present species�察�the 

law of homonyms will not permit it to stand。The name proposed refers to 

the abundant display of capillary radial spines�察�which is probably the most 

notable feature。
