Wissadula paniculata Hose, sp. nov. 



A small shrub 15 to 21 dm. high; leaves ovate, acuminate, cordate at base, 7 to 10 

 cm. long, short-petioled, somewhat stellate on both surfaces ; flowers in dense ter- 

 minal panicles; pedicels slender, 1 to 2 cm. long, jointed a short distance below the 



flower; calyx 6 i long; sepals triangular, shortly acuminate, stellate; petals 



yellow; carpels about 8, strongly apicnlate. 



Collected by Dr. E. Palmer near Ymata, sinaloa, September 25 to October 8, 1891 

 (No. 1743). 



This species is near IV. xcabra, but seenis to differ in the rougher pubescence of the 

 leaves and calyx, the more acuminate buds and sepals, smaller calyx, and smaller 

 and strongly apicnlate carpels. 



Wissadula acuminata Rose, Con tr. Nat. Herb. 5:144. 1897. 



The type specimen (Type No. 1515) is in the National Herbarium.

 Abutilon holosericeum Scheele, Linnaja, 21:471. 1818. 



Our material under this name seems to represent 3 forms, but until a much fuller 

 suite of specimens can be examined it seems best to leave them all undisturbed. 

 The slender sepals a}> pear to be associated with the blunter carpels and vice versa. 

 A. holoaericeum var. (Palmer's No. 112) has nothing to do with this species, but is a 

 good Abutilon.

The type specimen (Type No. 475) is in the National Herbarium. 



Wissadula trilobata (Hemsley) Rose; Abutilon trilobatnm Hemsley, Diag. PI. Nov. 

 pt. 2:21. 1879. 



We have a duplicate type (Type No. 184) of this species in the National Herbarium 

 which possesses all the peculiarities of the genus Wissadula as it has been so aptly 

 described by Dr. Robinson in the Synoptical Flora. Mr. Hemsley states that the 

 cells arc. often 5 or 6 ovuled, but all those which I have examined have 3 ovules, two 

 in the upper and one in the lower section of the cell, as is always found in this genus. 



Collected by Parry & Palmer, near San Luis Potosi, 1878 (No. 81), and more 

 recently by A. Dnges, near Guanajuato, September, 1889 (No. 287). 



Here may yet be referred /('. acuminata Rose, but, as the specimens at hand show a 

 slight difference, it seems best to keep them distinct uutil more material is collected 

 of both. 



In my discussion of Wissadula hirmtiftora and its forms, in 1895, ' 1 suggested that 

 it contained several good species, and that they seemed to indicate a good subgenus. 

 A recent review of this material confirms the results of my previous study, and I 

 now feel warranted in disposing of them as follows: 

 Bastardiastrum Rose, § nov. 



Carpels 3, rounded at apex; stamens cleft to the base; flowers violet.

 hirsxttijlora Presl, Reliq. Haenk. 2 : 112. 1836. 



Collected by Dr. E. Palmer at Colima, Colima, February 27 and 28, 1891. These 

 specimens have been identified by Mr. E. G. Baker of the British Museum. The type 

 is reported from Acapulco, but both Palmer and Nelson have recently visited this 

 port without, being able to And the species. 



"Wissadula cincta (Brandegee) Rose; Abutilon cinctum Brandegee, Zoe, 3: 318. 

 1893. 

 The type collected by Mr. T. S. Brandegee in 1892 comes from Las Durasnellas, State 

 of Sonora. A fragment (Type No. 194) is in the National Herbarium. The plant had 

 been previously collected by Dr. E. Palmer (in 1890) near Alamos, same State (No. 

 381), and has since been collected by E. A. Goldman at Alamos (January 29, 1899;
