the name, as we have above, to Pfeiffer, it was fully described and figured by Link and Ot

 was obtained by MaUison, as we state above, their illustration shows a very differe: 

 flower from the one figured in the Botanical Register and suggests that it was from 



different plant, although doubtless produced from the same pari

 are varieties Junkii, noihus, scoUi, and smithii, all in Walpers (Repert. Bot. 2: 278.

We 



tried to have it re-collected but so far have failed; in putting forth this effort we have suc- 

 ceeded in discovering another species which is described below as new. 



The binominal A. flagriformis appeared in Lemaire, Les Cactees, page 58, 1868, but 

 it is not formally published at that place. 



"^Cactus mallisonii is credited by the Index Kewensis to Loudon's Encyclopedia (Suppl. i. 1202. 1840), but it 

 appears there under Cereus.
