Florestina platyphylla. Mr. Piiugle's no. 4075, collected on 

 Moute Alban, Oaxaca, and described in the Am. Jour. Sci. ser. 3, L. 

 156, as Schukltria platyphylla, appears upon furtlier examination to be 

 better placed in Florestina. 



Dtsodia serratifolia, DC. A specimen collected by L. C. Smith, 

 below Jayacatlan, at 3,500 feet altitude, 9 P'ebruary, 1895, corresponds 

 with Ghiesbreght's no. 519, and with a fragment of the type from the 

 De Candollean Herbarium, in all respects, exce[)t in having the leaves 

 mostly alternate, not opposite as hitherto described. The uppermost 

 only are subopposite. 



Liabuji GLAiiKUM, Hemsl. (Biol. Cent.-Am. Bot. ii. 232). This 

 showy species, originally collected by Bourgeau, no. 1401, at Cuernavaca, 

 in 1865, has now been rediscovered by Mr. Priugle in the same locality. 

 His excellent specimens show the flowers to be bright orange-yellow and 

 the leaves normally attenuate. Mr. Pringle notes that the plant attains 

 a height of 15 feet.
