860. Limnosium Sinclairii, sp. n., floribus monoicis, spathis unifloris, masculis in scapo brevi 
pluribus, foemineis solitariis.—Guayaquil. 
Planta natans, stolonifera, acaulis, Folia radicalia petiolo 4-1-pollicari, ovata vel orbiculata, obtusa, 
integerrima, basi rotundato-truncata, rarius leviter cordata vel in petiolum angustata, 10-15 lin. longa, venulis 
evidentioribus circa quinque in petiolum convergentibus, minoribus pluribus subparallelis et fenestrato-reticu- 
latis. Scapi masculi nunc 2-6 lin. longi, nunc subnulli, spathis 2-3 brevibus laxis membranaceis bine fissis 
terminati, Pedunculi intra spathas solitarii, uniflori, 2-4 poll. longi. Perigonium corollinum, 6-partitum, 
laciniis subzequalibus elliptico-oblongis, 3 exterioribus viridioribus. Stamina 6; filamenta brevissima, plana, 
basi connata; antheree oblongee. Styli rudimenta 2, filiformia, Spathz fcemines, certe in eadem planta cum 
- maaribus, subsessiles, solitarize, tubulosw, 3-5 lin. longs, hinc fisse, demum explanatee. Pedunculus vix spatham 
superans vel interdum ei brevior. Perigonium fere maris sed superum (vel potius tubo ovario adhzrente 
donatum). Stamina nulla. Styli 6, filiformes, bifidi, lobis stigmatosis. Ovarium triloculare, omnino inferum. 
Ovula in loculis numerosa, hyalina. Capsula (immatura) ovoidea, nuda. Semina pauca, more Hydrocharida- 
cearum echinulata. 
The female flowers are so imperfect that I am not quite certain as to the 
details of their structure.
