Dr. K, Schumann may be correct, from his great linguistic knowledge, in 
altering the spelling to Sansibar. I would gladly accept the correction if it would 
obviate our Indices being afflicted for all time with two words (instead of one), but 
Dr. Schumann’s alteration of a first letter has made me helpless.

This plant appears most like C. niveus, Retz., but is on a very much smaller 
scale. The heads, though dense, are evidently compound, which approximates it to 
the succeeding section.
