MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 9, No. 3 



\ 



Terr. Amazonas, Venezuela, elev. 1500 m, Feb. 17-19, 1953, Maguire & Maguire 

 35283 (NY). Paratypes: Shrub or small tree 2-3 m tall, ligules 8-10 yellow, 

 infrequent on rocky slopes along middle section, main branch, lefthand fork of 

 Cano Yutaje, Cerro Yutaje, elev. 1300-1400 m, Feb. 15, 1953, Maguire & Maguire 

 35239; slender tree 3- 5 m tall, ligules yellow, frequent in cumbre of Cerro Coro- 

 Coro, Terr. Amazonas, Venezuela, elev. 1500 m, Mar. 2, 1953, Maguire & Maguire 

 35429; virgate shrub to 5 m, rays 5-7 yellow, occasional in opening in cloud 

 forest below Tower Escarpment, Ilu-tepuf, Edo. Bolivar, Venezuela, elev. 1900 

 m, Mar. 11, 1952, Maguire 33372; shrub 4 m tall, rays yellow, frequent on mon- 

 tane slopes between Camp 2 and base of escarpment, Ilu-tepuf, elev. 1900-2100 

 m, Mar. 16, 1952, Maguire 33452; shrub 10-12 ft tall, rays and disc florets 

 yellow, lower mixed Bonnetia forest above southeast-facing upper shoulder on 

 slope leading to summit of Apacara-tepuf, Chimanta Massif, Edo. Bolivar, Vene- 

 zuela, elev. 2000-2150 m, June 20, 1953, Steyermark 75812. 



Steyermark (Fieldiana Bot. 28: 676. 1953) discussed the probable synonomy 

 of V. schomburgkii and V. guianensis Baker; we have confirmed this by examina- 

 tion of Schomburgk 654/993 and 2945, kindly lent by Kew. The typical eligulate 

 subspecies has also been collected, apart from Steyermark's topotypical 58670, 

 on Serra do Sol (Maguire & Maguire 40447). where the field notes indicate a 

 completely eligulate population. The ligulate and disc achenes seem to show 

 no differences so old- flowering or fruiting material, such as Steyermark & Wur- 

 dack 985 from Chimanta, cannot surely be placed; the geographic anology would 

 place all Chimanta collections in subsp. ligulata. 



V. pilosa Maguire & Wurdack, a ligulate species to be based on Phelps & 

 Hitchcock 424 from Uaipan-tepui and also represented by Cardona 2628 from 

 Auyan-tepui", is closely related to V. schomburgkii but has much denser lower 

 leaf surface pubescence, persistently pubescent upper leaf surfaces, and densely 

 pubescent involucral bracts which are all approximately the same length. 

 Steyermark 60070, from Soropan-tepul, has rayed capitula, with leaves more 

 pubescent than usual for V. schomburgkii subsp. ligulata,' while suggestive of 

 V. pilosa, this specimen seems best assigned to V. schomburgkii subsp. ligulata 

 because of the gradate sparsely puberulent bracts. 



In revising Verbesina sect. Lipactinia (Am. Jour. Bot. 12: 625-640. 1925), 

 Blake noted that some species, such as V. arborea and its allies, may occasion- 

 ally or always have a few small rays; probably the entire genus must be re- 

 evaluated in light of the lesser importance of the presence or absency of rays. 

 Head size likewise seems to be a rather tenuous character, with floret counts 

 in collections of V. schomburgkii subsp. ligulata from Yutaje ranging from 20 to 

 45. m glabrata H. & A. is very closely related to V. schomburgkii and V. pilosa; 

 the Brazilian species differs from both in its thinner leaves and longer pedicels. 

 V. pilosa also differs from V. glabrata in its non-gradate phyllaries, and V. 

 schomburgkii has proportionately wider, more or less obovate, short-acuminate 

 leaves. 



Calea cardonae Maguire & Wurdack, Mem. N. Y. Bot. Gard. 8: 146 (1953) var. 

 cardonae. 



TYPE: Acopan-tepui, Guayana, Venezuela, F. Cardona 2274 (US). 

 The typical form of C% cardonae as known at this time is confined to the 

 Chimanta massif. 



Calea cardonae var. orientalis Maguire & Wurdack, var. nov. 



A var. cardonae similis, sed laminis foliorum firme chartaceis, anguste vel 

 late ellipticis, 2-4(5) cm longis, 10-18(25) mm latis.
