 pedunculo folia subicquante filiformi ; involucro haemispherico, bracteis 

 ovalibus adpressis immarginatis ; ligulis ovalibus (lin. circiter 4 longis) 

 aurantiacis subtus mox pallidis ; paleis receptaculi lanceolatis apice 

 molli sensim attenuatis ; acheniis obovatis bidentatis, ala callosa cilio- 

 lata, faciebus papillosis. — Tequila, base of hills and roadsides. (386.)

 Rio Blanco, in moist shady places; June. (36.) 



J^GERiA PEDUNCULATA, Ilook. & Am. Bot. Beecli. 299. In- 

 stead of a span. Palmer's specimens are a foot or two high, and 

 1-7-cephalous. The ligules, 8 or 9 in number, are over two lines 

 long, and the golden yellow heads make the plant showy according to 

 the collector's notes. The root is annual. The outer paleas much 

 surpass the achenes and fully embrace them ; the inner are gradually 

 narrower, smaller, and subulate. Guadahijara, in swamps, in great 

 masses; September. (427.) — The original in herb. Kew is a poor 

 and monocephalous specimen. 



Gymnolomia squarrosa, Hemsl. 1. c. 2. 163. (Zalazaria, Schultz 

 Bip. in Flora, 1864, 217.) Guadalajara; September. (486.) — Rio

 patentibus aut strigillosa-appressis undique hispida; caulibus subsoli- 

 tariis 2-3-pedalibus e rhizomate nodoso valido parum ramosis apice 

 laxe oligocephalis ; foliis crassiusculis oblongis et sublanceolatis sessili- 

 bus plerumque obtusis nunc serrulatis nunc subintegerrimis tripli- 

 nerviis saepius tripollicaribus ; pedunculis spithamajis nudis ; capitulo 

 subgloboso semipollicem diametro ; ligulis plurimis oblongis discum 

 convexum baud superantibus ; involucri brevis bracteis oblongis ad- 

 pressis, apice brevi tan turn squarroso-patente ; receptaculo convexo 

 parum conico. — Rio Blanco, sides of ravines ; September. In two 

 forms growing together; one (533) with yellow rays, "rarely shaded 

 with dark brown " ; the other (531) " with dark brown rays " ; disk in 

 both forms yellow, becoming fuscous. It bears some resemblance to 

 Ilemsley's G. Jlava, but the bracts of the involucre much smaller, 

 shorter and closer, and in other respects abundantly different.
