THE CACTACEAE. 



although in but one locahty. A bountiful supply of living material was sent home, several 

 photographs were taken, and fruit and seeds obtained. 



Opuntia tuheriformis Philippi (Anal. Mus. Nac. Chile 1891": 28. 1891), referred here 

 by Schumann, doubtless belongs elsewhere. It may possibly belong to some Platyopuntia, 

 for it is described as having ovate joints only 5 mm. thick. It comes from the foot of the 

 Andes in the Province of Tarapaca, Chile.

Figure 105 represents a joint of a plant collected by Dr. Rose at Mendoza, Argentina, 

 in 1915. 



61. Opuntia rauppiana Schumann, Monatsschr. Kakteenk. 9 : 118. 



1899. 



Joints ellipsoid, rounded at each end, somewhat tubercu- 

 late, dark green or becoming graj'ish green, 7 cm. long by 4 cm. 

 in greatest diameter; glochids yellow, 5 cm. long; spines 12 to 

 14, sometimes as many as 20, very weak, almost bristle-like, 

 2 cm. long, hardly pungent. 



Type locality: In the Andes. 



Distribution: BoHvia, according to Schumann. 



Little is known of the habit of this plant, as only one 

 joint is figured and this appears to be a sickly greenhouse 

 specimen. It suggests some of the species which grow in 

 large clumps Hke the one figured as Opuntia grata by Fries.

62. Opuntia subterranea R. E. Fries, Nov. Act. Soc. Sci. Upsal. IV. i^: 122. 1905. 



Almost buried in the sand, simple or few-branched from a thick root 7 to 12 cm. deep: joints 

 terete, 2 to 4 cm. long; tubercles low; spines i to 7, all radial, short, whitish, recurved, appressed;
