The sliaiie aud size of the fruit resembles that of the species of Cratcem (No. 

 1013) collected here also. These specimens do not belong to any described 

 species, so far as I can learn, and the genus has not been re])orted previou.sly 

 from Mexico. It seems to belong in Morisonia, but in the absence of llowers it 

 is better to refer it doubtfully, as above. 

 Porchhammeria pallida Liebm. Kjoeb.Videusk. Meddel. 185:1 94 (1854). A small 

 tree, 15 to 20 feet high, 5 to 8 inches in diameter, with a largo top and a great

 long), 8 to 12 lines broad; calyx of male Mowers minute or wanting: m dower 

 wliile in full leaf. Ou a sandy beach near Mauzjinillo, March 2 to 18, 1891. iN'o. 

 i;i33, in flower; No. 1348, with inuuature fruit; No. 1366, Avith leaves only. 



The tree is simiewhat taller Avith the leaves larger than in the type, but in other 

 respects it agrees with it. Only the nuilo flowers were collected. This is a very 

 rare plant in herbaria and has not been collected for many years. It was lirst 

 seen and describ<Hl by F. Liebmann, and is now collected the second time. 



In habit and flowers the following new species is closely allied:
