Spruce, in his notes, mentions having sent male and female specimens ; but all the 



spicula? I have examined contain male flowers only. In foliage this approaches very 



closely to G. latifoUa ; hut the spicultc are very difieront, and in this latter respect it 



approaches G. amplexifolia, from which, however, it is well distinguished by having very 



simple instead of compound inflorescence.

Ovarium oblongum, apice attcnuatum ct pilosum. 



This species has narrow loaves, very similar to those of G . aiif/iislifolia ; but the spicula? 



(sometimes very hirsute, but always more or less so) distinguish it at once from all other 



species with large spiculae. The squamula? are diff'erent from those of all other species. 



Two are generally, if not always, united at the base, and are deeply bifid to near the 



middle, many-nerved in the lower portion; the upper half has no trace of a nerve, 



but is covered over with very small hairs, which arc only visible under a high power. 



None of the spiculte which I have examined are dia>cous.
