38 PLANTS "WRIGHTIAN^. 



SAPINDACE^. 



97. Ungnadia speciosa, Endl. Atakt. t. 36; Gray, Gen. III. 2. t. 178, 179, Sf PI. 

 Lindh. 2. p. 167. Near Austin, in flower; on the Leona, Western Texas, in fruit. 



f Sapindus marginatus, Willd.j Gray, Gen. III. 2. t. 180. Western Texas. — 

 Sapindus Manatensis, Shuttleworth, PL Rugel. No. 115, from the Manate Eiver, 

 Southern Florida, is the form of this species with nearly marginless petioles : it 

 also occurs in Gregg's collection from Northern Mexico. 



98. Serjania .'' aff. S. racemosee. Along the Eio Grande, Southern Texas. In 

 flower, and with some barely forming fruit, which in one specimen has a short 

 basal wing plainly indicated, while another appears as if it would have the pyriform 

 fruit of a PauUinia. The foliage is much as in that named Serjania race- 

 mosa, in Plantce Hartwegiance (which Eaton and Edwards also gathered near Mon- 

 terey along with a new Urvilleea *) ; but the leaflets are more obovate and blunter, 

 less serrate, though sparingly incised. It cannot safely be described until the full- 

 grown fruit is known. 



POLYGALACEiE. 



99. PoLYGALA ALBA, Nutt. ! Gen. 2. p. 87 ; Torr. in Nicollet, Rep. p. 145. P. 

 Beyrichii, Torr. 8f Gray, Fl. 1. p. 670. P. bicolor, II.B.K. ! Nov. Gen. 8r 8p. 5. 

 p. 394. t. 507 (1821). P. scoparia, Benth. PI ! Hartw. no. 30, non II.B.K. Val- 

 leys in the mountains beyond the Limpia; Aug. — No. 371 of Gregg's collection, 

 from San Antonio de las Alanzanes, with rather larger flowers that turn orange or 

 reddish, is exactly Kunth's P. bicolor, according to his figure, &c., and is different 

 from the more slender forms, gathered in Northern Mexico by Hartweg (No. 30), 

 Coulter (No. 275), Seemann, and Gregg, which in all respects agree with Nuttall's 

 prior P. alba. 



100. P. scoparia, H. B. K. Nov. Gen. 8c 8p. 5. p. 399 : var. multicaulis : cauli- 

 bus e basi abbreviata vel e radice lignescente perplurimis fasciculatis ; foliis lineari- 

 subulatis. — Mountains near El Paso, New Mexico ; also farther east ; Aug., 

 Sept. — This well agrees with an original specimen in the Paris Museum, with 

 which I have compared it, as well as with Kunth's detailed description, ex- 

 cept that the fasciculated slender stems, a span or more in height, divide at once 

 next the ground from very short persistent bases, springing from the thickish, per- 

 pendicular root ; and the stigma, which is the same as in the plant of Humboldt, is 



of small height. Leaves half an inch long, many of them fascicled. Petals probably purplish. Fructif- 

 erous pedicels drooping. Wings of the fruit three lines wide, the dorsal one even rather larger than the 

 lateral. (Hiraea sericea, A. Juss. in St. Hil. is Tetrapterys sericea, A. Juss. Mem. Malpigh.) 



* Urvill^a Mexicana (sp. nov.) : tomentulosa, trifoliolata ; foliolis ovatis acutis duplicato-senatis 

 subincisis subtus moUiter tomentosis ; petiolulis marginatis ; racemis elongatis ; squamulis petalorum longis- 

 sime barbato-ciliatis apice cucuUato-appendiculatis. — Near Monterey, Br. Edwards and Major Eaton, 

 Br. Gregg. — A climbing vine, with larger flowers than U. ulmacea, as large as those of Cardiospermum 

 Halicacabum. Squamulte of the petals furnished with an apical appendage behind the inflexed tip, which 

 in two of them is longer and acute. Fruit much as in the figure of U. ulmacea, very thin and membrana- 

 ceous.
