1012 BULLETIN DE L’HERBIER BOISSIER (2€ SÉR.). (234) 
This Hassler 8381 is = Lindmann, n. 2379, collected in Matto Grosso und 
is in a similar young state. 
So far as I see from these young plants they may be Mariscus cylindricus 
Ell. but it is a plant from the Eastern States of North America. 
Mariscus rufus U. B. K. 
Nov. Gen. et Spec. I, 216, t. 67; Lindm. List. Regn. Cyper., 10. 
This is not the usual color of M. rufus; I suppose it to be a «forma umbrosa». 
The nuis are here ripe so that I feel confident that it is M. rufus H. B. K.

In calidioribus utriusque orbis; in Asia Austral. Orient. cum Oceania 
frequens, in America vulgaris. 
0,5-1 m. in stagno in regione cursus superioris fluminis Apa. Dec., 
: This is a slender form, the secondary umbels with very small bracis. 
This species has more than a hundred names; but N. L. Britton agrees with 
me that ıt must all be one species.
