MULFORD EXPLORATION OF THE AMAZON VALLEY 



335 



lightly cordate base and acute or slightly mucronate summit, 

 entire, densely and softly pnbeseent on both surfaces, the vena- 

 tion rather stout but inconspicuous. Umbels solitary in the axils, 

 mostly simple, rather dense on erect j)eduncles shorter than their 

 leaves, mostly fifteen or fewer-flowered, the pedicels 3 or 4 mm. 

 long, subtended by small setaceous bractlets. Corolla-tube 

 nearly hemispheric, 2.5 mm. long, the lobes 5 mm. long, lanceo- 

 late, obtuse, recurved and twisted. Corona of 5 erect distinct 

 lanceolate obtuse pilose entire ligules, 3 to 4 mm. long, unay)pend- 

 aged and adnate to the lower half of the stamen-tul)e. Anther- 

 appendages erect, connate midway, thickened and hardened. 

 Styles 5 mm. long, united half way, pilose, the branches slightly 

 flattened. 



Reyes, 1,000 feet, H. H. Rushy, September, 1921 {no. 19 95- A). 

 Very near G. macroglossa, from which it differs in the higher 

 adnation of the corona, the longer corolla-tube, the very distinc- 

 tive indurated anther-appendages and the shorter and less 

 united stouter styles. Both species, together with G. Martii, 

 grow in open grassy places, the plants scattered singly amidst 

 the grass. G. macroglossa is rather more inclined to grow in 

 partially shaded places. 



Gothofreda Pearsoni 



Softly white-pubescent. Stems elongate, twining, terete, 

 rather stout. Petioles to 4 cm. long, flattened on the upper sur- 

 face, reddish, like the principal veins of the lower surface. 

 Blades to 9 cm. long, and half as broad, ovate, cordate with a 

 deep and narrow sinus and rounded lobes, abruptly acuminate 

 with attenuate apex, thin, softly pubescent, especially beneath, 

 with 4 pairs of basal nerves in addition to the midrib sharply 

 prominent beneath. Cymes sessile in the axil, mostly about 

 5-flowered, the pedicels about 4 mm. long, slender. Calyx-lobes 

 3.5 mm. long, subulate, attenuate, green. Corollai more than 

 twice the length of the calyx, the lobes acuminate, tomentose. 

 Ligules of the crown about 1 mm. long, erect, ovate, obtuse. 

 Appendages of the stamens longer than the anthers, subulate, 

 acuminate, erect. Corpuscles nearly 1 nun. long, the pollinia 

 shorter, narrow. Beak of the stigma parted two thirds of the 

 way, the branches extending nearly the length of the corolla, 

 stout, puberulent. 



Rurrenabaque, 1,000 feet, M. Cardenas, January 9, 1922 (no. 

 2035). Species dedicated to Dr. Pearson, the talented ichthy- 

 ologist of the Expedition.
