On page 37, vol. i, under Nopalea auberi, insert: 



Opuntia auberi was described as from Cuba, but as no Nopalea is known from Cuba 

 we have been unable to account for this reference. The following incidents may explain it : 



L. Pfeiffer described the plant in 1840 just after his return from Cuba, where he had 

 gone with Otto in 1838. At Havana they visited the Botanical Garden, then in charge of 

 Pedro Auber, for whom this plant was doubtless named. It is also stated that, although 

 Pfeiffer made this trip especially to gather cacti, he saw only one species, Opuntia horrida. 

 The probabihties, therefore, are that this plant was obtained from the Botanical Garden 

 at Havana, perhaps with a statement from Auber that it was Cuban. 



On page 37, vol. i, under Nopalea dejecta, add the synonym: Nopalea angustifrons* 

 lyindberg. Act. Soc. Sc. Fenn. 10: 123. 1871. 



Add to illustrations: Act. Soc. Sc. Fenn. 10: pi. 2, as Nopalea angustifrons. 



On page 41, vol. i, under Maihuenia poeppigii, add to illustrations: Gartenflora 30: 

 412, as Pereskia poeppigii. 



On page 42, vol. i, under Maihuenia brachydelphys, insert the synonym: Opuntia 

 brachydelphis Schumann in Just, Bot. Jahresb. 26^: 343. 1898. 



Insert: Mammillaria brachydelphis is a clerical error for Opuntia brachydelphis. 



On page 42, vol. i, under Opuntia, add the synonym: Cactus Lemaire, f Cactees 86. 

 1868. Not Linnaeus, 1753. 



On page 46, vol. i, under Opuntia ramosissima, insert: Opuntia tessellata denudata, 

 according to C. R. Orcutt, is only a form — spiny joints frequently occurring on the same 

 plant with the spineless form; it is common in the Mojave Desert, California. It was 

 mentioned by Alverson (Cact. Cat. 6) while 0. ramosissima denudata is listed by Weinberg 

 (Cacti 22). 0. ramosissima cristata is mentioned by Schelle (Handb. Kakteenk. 41. 1907). 



Also add to illustrations: Cact. Journ. i: pi. for February; Monatsschr. Kakteenk.

On page 47, vol. i, under Opuntia leptocaulis, add the synonym: Opuntia californica 

 Engelmann in Emory, Mil. Reconn. 158. 1848. 



Also insert: Opuntia stipata (Schumann, Index Gesamtb. Kakteen 830. 1898) refers to 

 0. leptocaulis stipata. 



Also add to illustrations: Emory, Mil. Reconn. 158. No. 11, as Opuntia californica; 

 Gartenwelt 11: 75, as 0. vaginata; Carnegie Inst. Wash. 269: pi. 10, f. 89; pi. 11, f. 96;

 Gart. Zeit. 25: 475. f. 9, No. 21. 



On page 49, vol. i, under Opuntia caribaea, insert: Dr. Britton endeavored to find 

 this plant in Trinidad in 1920 and 1921 but failed and he could not learn anything about 

 it. It appears probable that the drawing sent by Mr. Lockhart to Kew in 1825 was made 

 from a Venezuelan plant. 



On page 54, vol. i, under Opuntia clavellina, add to illustration: Karsten and Schenck, 

 Vegetationsbilder 13: pi. 18, in part. 



On page 56, vol. i, under Opuntia whipplei, in last line of description read cm. as mm. 



* The Index Kewensis refers this name to Opuntia leucacantha, but the illustration shows that it belongs to Nopalea. 

 t Lemaire in his Les Cactees, published in 1868, takes up the name Cactus for certain of the low, depressed, much 

 branched or cespitose species of Opuntia. He lists a number of these on pages 87 and 88, but as they are not connected 

 through pubhshed species their identification is made only by inference.
