Herba 0,4-0,5 petala caruiea in silva pr. Chololo, Dec., n. 6826. (Unie.). 
Tradescantia fluminensis Vellozo. 
Flor. Flumin. IH, 140, t. 152; T. albiflora Kunth in Flor. Bras. Ill, 
pars, I, p. 250. 
Herba procumbens 0,3-0.8 petala alba folia cuprea inter rupes aridos in col- 
libus pr. Tobaty, Sept., n. 6093. 
Tradescantia radiata C. B. Clarke spec. nova. 
Seminibus ex embryostegia radiatim costalis, inter costas traheculatis ; cetero 
quia ut. T. multiflora Sw.; slamina 6 fertilia — omnino ut T. multiflore — 
semina 6. 
This plant is suspiciously like T. multiflora Sw.; but in all the material of 
that common species, I find the seeds reticulate as stated in DC. Monogr. V, mi, 
p- 306.

n. 8493

0,15-0,45 pelala rosea, in colle Tobaty, Mart., n. 4035. 
Commelina guaranitica CG. B. Clarke spec. nov. 
There is no South American Gommelina in Herb. Kew that matches this as to 
leaves or indumentum. I cannot find one capsule with seeds on these specimens, 
so that I do not know the affinity, of care to give a specific name I should guet 
the species Lo be near C. erecla L. But no form of C. erecta L. here (or of 
C. Virginica) shows this dense soft universal indumentum.
