confirmed the apparent identity. This is by no means an isolated case 

 of the occurrence of identical species in Ecuador and Guatemala, but 

 it has peculiar interest from the marked character and rarity of the 

 plant concerned. Mr. Beam's specimens were collected at Los Amates, 

 Guatemala, 10 February, 1905, and distributed as no. 97 of his set. 

 He writes that only a few plants were found, and that these were growing 

 in rather wet situations deep in the virgin forest. An interesting 

 morphological as well as systematic account of the species is given 

 in Professor Hackel's original characterization, Oest. Bot. Zeitschr. xl, 

 111 (1890). 



Fuirena zacapana Bartlett, n. sp., rhizomate perpendiculari elon- 

 gato modice incrassato ; culmis 9 dm. longis gracilibus ascendentibus 

 hispidis vel ad basin glabriusculis ca. 8-foliis ; foliorum vaginis 1.5-3 

 cm. longis dense hispidis ; foliis linearibus utrinque hispidis usque ad 

 5 mm. latis, in partibus culmi inferioribus 1 cm. longis superne 9 cm. 

 longis ; capitulis 3-4, infimo solitario in axilla folii supremi peduncu- 

 iato, reliquis plus minusve approximatis ; spiculis in capitulo quoque 

 3-6 ovatis 4 mm. latis 8 mm. longis ; squamis brunneis pubescentibus 

 in spiculae basi suborbiculatis in apice ovatis trinerviis, in dorso recti- 

 aristatis ; sepalis 3 brunneis glabris duriusculis ovatis basi subcordatis 

 longe unguiculatis apice rotundatis infra apicem in dorso breviaristatis, 

 aristis retrorsum scabris ; setulis 3 cum sepalis alternantibus superne 

 retrorsum scabris quam achaenio multo brevioribus ; achaenio longe 

 stipitato mucronato sepala paene aequante. — In swamps, Gualan, 

 Department of Zacapa, Guatemala, 13 January, 1905, C. C. Deam, 

 no. 423 (type, in hb. Gray). This very distinct species is nearest to 

 F. simplea' Vahl, from which it differs in its lax habit, in the extreme 

 development of pubescence on the leaf-sheaths, in its short perianth- 

 bristles, and long-stiped achene.

 tis, lenticellis paucis sparsis ; foliis membranaceis late ovatis cordatis 

 breviter caudato-acuminatis serratis 17 cm. longis 11 cm. latis supra 

 more generis sparse pilosis et cystolithis radiantibus instructis subtus 

 molliter tomentosis griseis, apice caudiformi ca. 1 cm. longo, nervis 

 lateralibus utrinque 4-5; petiolo 1.7-2 cm. vel ultra longo tomentoso; 

 inflorescentiis omnino sessilibus ca. 1 cm. supra basin furcatis ; ramis 

 1-2 dm. longis griseo-tomentosis unilateraliter floriferis ; floribus 9
