Colfocted by Mr. C. G, Pringlo on calcareous hills, Tehuacan, State of Puebla, 

 1895 (No. 6289); and by Mr. E. W. Nelson near Nenton, Guatemala, altitude 912 

 meters, December 13, 189.") (No. 3522). This species lias only been known before 

 from the specimens of Liebmanu from Consoqnitla. Mr. Nelson obtained excellent 

 fruiting specimens which answer the description except that the leaves are not quite 

 so long. On the other hand Mr. Pringle's plants, which are only in flower, have the 

 longer leaves, but none of them arc- obovate. I. have little hesitancy, however, in 

 referring both specimens as above. The species is new to the National Herbarium. 



i i Leaves large, glabrous. 

 *■ Leaves with lateral turns indistinct, obtuse, scarcely serrate, 



Wimmeria pallida Kadlk. in part. 



A spreading shrub 21 dm. high; leaves lanceolate, obtuse, with Blender cuneate 

 base, 5 to 8.7 cm. long, 2.5 to 5 cm. broad, petioles slender; fruit broader than long, 

 20 to 30 mm. broad. 



Collected by Dr. Edward Palmer near Acapulco, November, 1891 (No. 124). Wim- 

 meria eonfusa was so called because it bad been confused with W. concolor and so 

 figured in Hooker's Icones. It was named in 1878 by Mr. Hemsley, who based it 

 upon Hartweg's plant; the same year Radlkofer described his W. pallida, basing 

 it in part upon Hartweg's specimens as figured in Hooker's icones, but also referring 

 it to specimens collected by Haenke (perhaps at Acapulco) and Liebniann. In the 

 Biologia this specieB is referred to IV. confusa and the confusion continued. Pal 

 mer's specimens I think belong to a different species from Hartweg's and I propose 

 to retain for them Kadlkofer's name of IV. pallida. The two species as thus sepa- 

 rated are very distinct both in fruit and foliage. 



-+- — leaves with lateral nerves move prominent, long-pctioled, finely and regularly 



serrate. 

 Wimmeria persifolia Kadi k. Sitzb. Math. Pliys. Akad. Muench. 8: 379. 1878, 



Shrub 4.6 meters high. 



Collected by Mr. C. G. Pringle at t'uernavaca, 1895 (No. 6210). 1 bis species, like 

 the above, is only known from Liebmann's collection. It was collected at Kjutlu, 

 State of Oaxaca. 



The above specimen seems properly referred, although the trail, is not so hirge as 

 described. The species is new to the National Herbarium. 



A SYNOPSIS OF THE AMERICAN SPECIES OF HERMANNIA. 



The genus Hermauniii in the first volume of the Biologia Centrali- 

 Ainericana is represented by ;t single species ( //. texana). The rare 

 //. inflata, redescribed below, was overlooked, while two other species 

 have recently been described. The genus is a large one, but is almost 

 wholly South African. The four species here referred to are the only 

 ones known on the American continent. 



The following key will be of aid in determining our American mate- 

 rial. 



t Calyx much inflated. 



Hermamiia inflata Pink & Otto, Ic. PI. Rev. 55, 1. 28. 1828. 



This species has been rare in collections and was entirely wanting in the National 

 Herbarium— in fact its publication has been overlooked by many. Dr, ( iray thought 

 it was simply a manuscript name. Mr. Hemsley omitted it from the fnsl volume of 

 the Biologia Centrali-Americana, while the writer was at first inclined to consider 

 Mr. Nelson's plant a new species. My specimens may be described as follows: 



Shrub, 12 to 18 dm. high; branches densely stellate- tomentoso; leaves ovate, 3.7 

 cm. or less long, obtuse, with broad cuneate base, 3.7 em. long; petioles short; stip-
