2. Antennaria (Mniodes) aretioides (Bacchans aretiodes, 

 Schultz Bip., Merope aretioides, Wedd. Chlor. And. t. 25), from the 

 Andes a little farther south, has more obovate, less truncate, and much 

 less villous leaves, papillose sterile ovaria (fertile plant not known), 

 and the bristles of the male pappus very gradually and moderately thick- 

 ened upwards. These distinctions are derived from Weddell's figure 

 and description, and from a small specimen of no. 1823 of Lechler's 

 collection, kindly communicated by Dr. Schultz. But what he has 

 communicated under the same name, from H^nke's reliquice, is plainly 

 the A. andina. 



Werneria, H. B. K. This interesting and now rather polymor- 

 phous andine genus, like its analogue Senecio, is either radiate or dis- 

 coid, the rays either yellow, white, or rose-color ; the branches of the 

 style are either truncate, or, in a few species, tipped with a setiform 

 appendage. In one remarkable species the receptacle is alveolate ; in 

 one or two the leaves on the branches, or some of them, are opposite ; 

 in several there are five abnormal nerves to the disk-corollas, occupy- 

 ing the axis of the lobes, as in De Candolle's Mesogramma ; but this is 

 an inconstant character. The collection of the Exploring Expedition 

 comprises the following species, viz. : — 



Werneria nubigena, H. B. K., including, with Weddell, W. dis- 

 ticha and graminifoUa, but not W. rigida (misprinted frigida by De 

 Candolle), which is apparently the larger form of W.pumila. 



Werneria Orbignyana, Wedd., var. breviradiata : involucri 

 laciniis 10-14 ligulas breves adgequantibus ; foliis s^epius integerrimis. 

 — High Andes of Peru, near Casa Cancha. This, which I had for- 

 merly named W. nuda, is perhaps W. nubigena var. caulescens, leio- 

 scapa, Wedd. 1. c. 



Werneria villosa (sp. nov.) : rhizomate repente ; caule florifero 

 gracili simplici usque ad capitulum parce folioso villoso-lanato ; foliis 

 angustissime linearibus primum villosis mox glabratis, summis brevi- 

 bus filiformibus capitulum bracteantibus seu involucrantibus, radicalibus 

 obtusis deorsum longe attenuatis, basi dilatata scariosa intus fulvo-crin- 

 ita ; involucro 12-15-fido, lobis lineari-lanceolatis margine scariosis ; 

 ligulis exsertis ; styli ramis apice truncate penicillato-hispidis ; achenio 

 glabro. — High Andes of Peru near Alpamarca. — To be compared 

 with W. staticcefolia, Wedd., especially the var. celmisioides ; but that 

 is said to have the branches of the style subulate, &c.
