138 DELESSERIACEAE 
liferations show conspicuous hemispherical or lunate-discoid || 
apical cells and a regularly seriate arrangement of the cells that : 
are cut off from them. The apices of the thallus, in Montagne's 
specimen, are so thin, etiolated, and so crushed into the paper in 
mounting that we have been unable (without risking serious 
injury to the specimen) to obtain a view of the main apical cells. 
The original specimen is, we believe, sterile, the ''sporidia intensius 
colorata" of Montagne appearing to be simply groups of cells 
that have retained their rose-red endochrome in *he more or less 
etiolated apical portions of the thallus. The chromoplasts of 
such cells are often irregularly divided somewhat as indicated in 
Montagne's figure 6. 
We have received from the herbarium of the Muséum d'His- 
toire Naturelle of Paris a specimen of Delesseria leiphaemia, said 
to have been collected in Valparaiso, and communicated by 
M. R. E. Bustos of the Museo Nacional of Santiago de Chile. 
This specimen is of recent collection, is well preserved, and shows 
well the arrangement of the cells at the apices of the main lobes 
of the thallus. These lobes are rounded, obtuse, and neither 
apiculate nor emarginate. Те apical cell is several times larger 
than those immediately adjacent and the adjacent derivative 
cells are in semicircular or arcuate rows. This specimen, also, 
appears to be sterile or perhaps shows incipient sporangia. 
stipital or imperfectly alate basal portions of the thallus are longer 
than in the original specimen, reaching sometimes a length oi. 
2-4 cm. 
Delesseria sinuosa (Good. & Woodw.) Lamour. has been 
reported from San Lorenzo, in the region of Callao, by Montagne 
(Voy. Bonite, Bot. Crypt. 112. 1846). 
Erythroglossum bipinnatifidum (Mont.) J. Ag. (Sp. Alg. 3: 
176. 1898. Delesseria bipinnatifida Mont. Fl. Boliv. 31. #4. 6. 
f. z. 1839) has been reported by J. Agardh (Sp. Alg. 2: 688. 
1852) from the shores of southern Peru as well as from Chile — 
(Valparaiso was the type locality), but it was possibly from that 
part of the older Peru that is now under the control of Chile. - 
I: does not occur in the collections made by Dr. Coker.
