Nemacladds longiplouus. Foliis radicalibus magis cano-birtis; 

 corolla tubulosa sepalis aequalibus a basi fere discretis sublinearibus 3-4- 

 plo longioribus, tubo fere integro ; filamentis longius monadelphis ; 

 ovario fusiformi ; capsula oblonga septo contrario subcompressa calyce 

 libero plus diiplo longiure ; seminibus turgide ovalibus. — S. E. Cali- 

 fornia, Wallace, Lemnion. A specimen of this, collected by Mr. Wal- 

 lace (probably between Los Angeles and San Bernardino), has long 

 been in our herbarium, but the charaoters have been noticed only nov? 

 upon the coming of fine specimens collected recently by Mr. Lemmon. 

 The flowers and fruit differ strikingly from those of iV^ ramosissimus, 

 and call for emendation of tlie generic character. In the new species 

 the calyx is actually free from the ovary and capsule, and 5-parted to 

 the base, and the long and narrow capsule is 2-valved from top to bot- 

 tom. It is very interesting to have a second species of this remarkable 

 genus; but it throws no additional light upon its affinities.
