112 PROCEEDINGS OF THE AMERICAN ACADEMY 



Plumbago scandens, Linn. At Guajuco, Nuevo Leon (2106) ; 

 240^ Parry & Palmer. 



Plumbago pulciiella, Boiss. Near San Luis Potosi (727 

 SchafFner), and at Guanajuato (Duges) where it is known as " Tiri- 

 cua " ; 240 Parry & Palmer, referred to the last species. 



Anagallis arvensis, Linn. At Saltillo (782), and about San 

 Luis Potosi (141 SchafFner). 



Centunculus minimus, Linn. Near Morales, San Luis Potosi 

 (124 Schaffner) ; oG9^ Parry & Palmer. 



Samolus ebracteatus, HBK. At Sutherland Springs, Texas 

 (781) ; a low form with very broadly spatulate leaves and small white 

 flowers. Also at Parras (783), a variety with large purple flowers. 

 569 Parry & Palmer is a very peculiar variety, with acutely oblanceo- 

 late and very narrowly petiolate leaves, and long acuminate calyx- 

 teeth. 



BuMELiA spinosa, DC. At Uvalde, Texas (156), and at Saltillo, 

 Coahuila (786). Agreeing satisfactorily with the figure of Mo(;ino & 

 Sesse, and differing from £. lanuginosa in its more spinose branches, 

 smaller leaves, and in the mottled seed slightly more narrowed at base. 

 It extends into Arizona, where it has been collected by Lemmon and 

 Pringle (distributed as B. paucijlora, Engelm.). A more canescent 

 form, from Parras (787), with shorter pedicels and less pubescent 

 calyx, is probably the same. 



DiosPYROS Texana, Scheele. From Uvalde, Texas (789), and 

 Guajuco, Nuevo Leon (784) ; also staminate specimens fi-ora near 

 Laredo, Texas (788). 



Menodora heterophylla, Moric. At San Antonio (790) and 

 Sutherland Springs, Texas (791). 



Menodora Coulteri, Gray. Locality not given; 300^ Parry & 

 Palmer. 571 Parry & Palmer, referred to this sjiecies, is a dwarf 

 small-flowered form of M. helianthemoides (570 Parry & Palmer), or 

 closely allied to it, and the same as 44 Gregg. 



Menodora longiflora, Gray. In the mountains north of Mon- 

 clova (792) ; both the usual glabrous form and a pubescent variety, 

 the M. pubens, Gray. The two forms were also distributed by Wright 

 under the same number (1695). At Juraz, Coahuila, specimens were 

 collected with unusually short corollas, not exceeding an inch in length 

 (794). 



Menodora scabra, Gray. At Juraz, on the Sabinas River, Coa- 

 huila (793). 



Menodora scoparia, Engelm. Probably the same locality (795).
