Species, ut mihi videtur, priori valde affinis, et, si 
characteres, quibus utraque melius distingui possit, firmiores 
detexerit quispiam, valde laetabor. Formae cellularum, saepe 
e massa, quam continent, ejusque forma, judicatae, vix con- 
stans est. Varietates allatas, ab auctoribus saepissime species 
descriptas, cum tantum ramositate thalli 1. ejusdem crassitie 
inter se differant, specifice diversas equidem habere non pos- 
sum, Harvcyi verba de Entcromorplia erecta (var. c. nostra), 
”Few plants are so sportive in size and ramification, and if 
all the varieties were described the species might easily be 
multiplied till we should have one for almost every marine 
pool”, in meam defensionem aflerens.
