Allionia montanensis Osterhont, Muhlcnbergia 1: 39. 1906. 



Oxybaphus linearis Robinson, Rhodora 10: 31. 1908. 



Allionia petrophila Standley, Contr. Nat. Herb. 12: 340. 1909. 



Type locality, "In Upper Louisiana."

Chihuahua: Rocky hills near Chihuahua, September, 1886, Pringle 340. 

 San Luis Potosi: Region of San Luis Potosi, 1878, Parry & Palmer 767. 



I have lately had the opportunity of examining the type of this species in the 

 Pursh herbarium, now in the herbarium of the Academy of Natural Sciences of Phila- 

 delphia. It was collected by Bradbury arid bears the locality "Louisiana." Its leaves 

 are rather wide and bright green; the inflorescence is rather sparse and narrow, some 

 of the involucres being axillary; it resembles very much the plant named Allionia 

 glandulifera by Prof. A ven. Nelson and I think that that species must be considered 

 a synonym of A. linearis. The type of Calymenia angustifolia was also examined 

 in the herbarium of the same institution. This and A. linearis are certainly the same. 

 Specimens of the type collection of A. petrophila in the National Herbarium have 

 manifestly pubescent fruit and it appears best to reduce that name to synonymy. 



15. Allionia aggregata (Orteg.) Spreng. Syst. Veg. 1: 384. 1825. 

 Calyxhymenia aggregata Orteg. Ilort. Matr. Dec. 3: 81. pi. 11. 1798.

 Oxybaphus aggregatus Vahl, Enura. PI. 2: 41. 1806, in part. 

 Calymenia aggregata Pers. Syn. PI. 1: 37. 1805. 



Allionia hirsuta aggregata A. Nelson, New Man. Rocky Mount. 173. 1910. 



Type locality, "In Nova Hispania." "Floret in Reg. Hort. Matrit. mense Au- 

 gusto et Septembri e seminibus missis per D. SesseV' 



No specimens of this have been seen. There is little doubt but that it is a young 

 form of some of the Mexican species listed elsewhere. The plate illustrates a plant with 

 axillary inflorescence, narrowly elliptic leaves, and hirsute stem. The only speci- 

 mens seen by the writer that could be referred here were collected in the north-central 

 part of the United States and are almost certainly immature or poorly grown plants 

 of Allionia hirsuta. Professor Nelson has properly referred to them as a subspecific 

 form of that species. True A. aggregata, however, is doubtless something very 

 different.
