52 The Botanical Gazette. [February. 



It seems probable that these two specles thus merged, with 

 some others, should be included in T. patula L.— San Carlos, 

 Depart. Quezaltenango, alt. 8,622 , December 1891, W. C. 



Shannon 598. . 



PECTIS CANESCENS HBK., var. Yillosior, n. var.— Stems 



and leaves much more woolly pubescent, the involucral bracts 

 densely so, being like those of P. Liebntannii Sch. Bip. — Santa 

 Rosa, Depart. Santa Rosa, alt. 3-4, 000«; March and May 

 1892; Heyde & Lux 3,40i and 3,4^3- 



Senecio Ghiesbreghtii Regel, var. IJspantanensis, n. 



var.— Leaves entire, elongated oblong and acuminate. — San 

 MiguelUspantan, Depart. Quiche, alt. 6-12,000", April 1892, 

 Heyde & Lttx 3,368; also distributed in previous coUection as 

 S. Ghiesbreghtii, no. 1,598, with leaves similar but with mar- 

 ginal mucros; also Botteri, 609 and 820 from Orizaba. In 

 looking over the allied tree-fofms, 5.. Ghiesbreghtii Regel, 

 5. grandifolius Less., and 5. arborescens Steetz, it becomes 

 evident that we are dealing probably with a single species 

 having leaves varying from pinnately divided to entire. S. 

 grandifoliiis Less. must certainly absorb 5. arborescens Steetz, 

 but I do not feel the same confidence as yet in such a dispo- 

 sition of 5. Ghiesbreghtii Regel, although Hemsleyrefers the 

 latter to 5. grandifolius, but keeps 5. arborescens distinct. 



Senecio Schumannianus Schauer. — Chiul, Depart. Qui- 

 che, alt. 8,000", April 1892, Heyde & Lux 3,377- I have no 

 record of the discovery of this interesting species other than 

 that of Aschenborn about Zimapan. Although no authentic 

 specimens have been accessible Schauer's description in Lin- 

 naea completely accords with our plant. 



Werneria NUBIGENA HBK.— Volcan de Tajumulco, De- 

 part. San Marcos, alt. 12,000", January 1892, W. C. Shan- 

 tion 607. A very interesting discovery of a high Andean 

 genus, not reported before north of the high mountains of 

 Bolivia. 



PEREZIOPSIS, n . gen. of MUTlSIACE^. — Heads rather fe w- 

 flowered (10-15), homogamous, the flowers perfect: involucre 

 conical, with three or four series of dry loosely imbricated 

 narrow bracts, the outer ones short and grading into the 

 bractlets, the inner ones becoming successively more elong- 

 ated: receptacle densely pilose: corolla elongated, deeply bi- 

 labiate, the upper lip broad and 4-toothed, the lower of a 

 single narrowly linear petal, all the lobes erect (not even
