acutis, membranacese. Stamina tria, jam perfecta, jam castrata. Ovarium oblongum ; styli distinct!, 

 graciles ; stigmata aspergilliformia, purpurea, demum subfusca. Idem flosculus in spicula pedicellata ejusdem 

 est structural et indolis, eo autem differens, quod valvula inferior fere integra est et inter duos denticulos 

 minutos apicis mucronulum brevissimum setaceum, quandoque et nullum omnino, emittit. 



[Our specimens from Mr. Millett, and those in Prof. Henslow's herbarium from Mr. Vachell, now lying 

 before us, some of which were examined by Nees v. Esenbeck, agree with the above description in every 

 particular, except that the lodicules of the male floret are actually as small as, and precisely similar to, those 

 of the bisexual one : in both they are somewhat cuneate and truncated, and not longer than the ovary. We 

 are therefore disposed to suspect some error of observation in those parts from which the specific name has 

 been derived ; nor can we readily account for it unless on the supposition that, while dissecting the flower, 

 the inflexed margins of one of the valvelets had been in part or wholly separated and supposed to be the 

 lodicules.]
