disk on the summit of the fruit here is white, in that red. The fruit 

 in this case is marked with 10-12 ribs, while in that there are 5-8 

 ribs. 



Psycliotria crocea, Sw., Prod., 44. 



Between Yilla Rica and Escoba (501); Pilcomayo River (877). 

 = Balansa 1738 a. January. 



This is apparently not Palicourea crocea, Schlecht., Linnsea, 

 xxviii, 525. 



Psychotrophum, P. Br. Hist. Jam., 160, is undoubtedly an older 

 name for the genus Psychotria, but we are retaining Psychotria, 

 because we are uncertain about Myrdiphyllum, P. Br., 1. c, 152, 

 which Dr. Kuntze says is also an equivalent, and has 8 pages 

 priority of place in Browne's work. — N. L. B. 



Geophila Tiolaefolia, D.C., Prod., iv, 537. 



Near Pirayu (661). April. 



A small trailing, somewhat succulent plant, growing in deep 

 woods, the stems rooting at the nodes. Leaves opposite, entire, 

 glabrous, cordate-ovate, acute or obtuse at the apex, the rounded 

 basal lobes divergent, 8-6 cm. long, 2^-5 cm. wide, on petioles 3-10 

 cm. long. Found only in fruit. Flowers said by DeCandolle to be 

 white, 3-7 or more in clusters at the end of an axillary peduncle 

 about as long as the petioles. Fruit an oval, pulpy, purplish-black 

 drupe, crowned with the persistent calyx, containing 2 coffee-shaped, 

 bony seeds.

Geophila reniformis, C. and S., Linnsea, 1829, p. 137. 



Near Pirayu (669). April. 



This species, found at the same time and place with no. 661, 

 differs from that in having much more slender stems, smaller leaves, 

 2-3 cm. long and about as wide, the lobes smaller and approximate, 

 shorter petioles and peduncles, fewer flowers (1-3), and scarlet 

 drupes. Not at all succulent. Both species have 1 or 2 lines of 

 short shaggy hairs on the petioles.
