Caum and Judd made the first collections of this plant in June, 1921 
observing that it was "most common on the ridge leading to Miller Peak" 
bin, (was) abundant also on the ridges to the east." (?). This endemic 
species was not seen again until May, 1960J when D. Yen found four plants 
growing near the summit of Millers Peak. The region around Millers Peak 
was traversed by most, if not all, o£ the parties visiting Nihoa. It" 
does not seem plausible that ^ other-<«Wn ..j would have missed the plant. 
.ovever, f,n-aranthus i brown.! j, is an annual and the ridges are the driest 
parts of the island. If it nas the delayed germination period and the 
rapid^life cycle that are common in many annuals, it very easily could 
nave been missed by the others, who collected during August, September 
and December. ' 1 -
