p. 298, Vol. III., the following should be added: 
R. bicolor. Bromelia bicolor (B. H. 1873, t. 14) is the same 
as this species; but B. Joinvillei and Hechtia pitcairniefolia 
yms of B. pitcairniafolia, while Ruckia Elemeeti is 
identical with 2. andina,

R. Joinvillei (Joinville’s). A synonym of R. piteairnicefolia. 
R. littoralis (seaside-loving). /., petals rose-red, lingulate, 
lin. long; filaments pink; head central, ljin. to 2in. in 
diameter, September to November. 7. about forty in a rosette, 
ensiform, acuminate, less than lft. long, Zin. broad, white- 
lepidote at back, the marginal prickles pungent. Colchagua,
