136 DELESSERIACEAE 
Aglaophyllum striolatum J. Ag. (Kütz. Sp. Alg. 868. 1849) was 
attributed to Lima by Kiitzing (‘‘v. s. in herb. Binder”). 
We have not seen it. It is apparently not mentioned in the 
writings of Agardh himself. De-Toni (Syll. Alg. 4: 661. 
1900) includes it, doubtfully, in the synonymy of the South 
African Nitophyllum fissum (Grev.) J. Ag. De-Toni, by the 
way, attributes the name to Sonder, which may be in truth | 
correct, although it is credited to J. Agardh in the place 
cited by De-Toni and where, only, the name seems to have 
appeared in print.

* This name is untenable under modern rules of nomenclature except by arbi- 
ing several genera and several NM of modern writers, it offers a good illustration

Delesseria sanguinea, the first species of Lamouroux’s first section of the genus, might 
airly be considered the type of Delesseria, but this is also the evident type of Hydro" 
кнр Stackh., which (altered to Hydrolapathum) has been maintained as generically 
distinct from the other ‘‘Delesserias” by Ruprecht, Le Jolis, J. Agardh, and € 
J. Agardh even maintained to the last (Anal. Alg. Cont. 4: 22-27. ,1897) tha
