Taxonomie : "Raddiella vanessiae is the smallest bambusoid grass yet known, even smaller than Raddiella minima Judz. & Zuloaga (Zuloaga & Judziewicz 1991; Zuloaga et al. 1993; Judziewicz et al. 1999). Table 1 shows that both R. minima and R. vanessiae have smaller leaves than the endemic Cuban olyroid Mniochloa pulchella (Griseb.) Chase (Zuloaga et al. 1993). The new species appears to be related to both R. minima (known only from the Brazilian type collection made about 1600 km to the south of French Guiana) and the widespread Neotropical species R. esenbeckii (Steud.) C.E. Calderón & Soderstr. but is much smaller than either one. The new species is also distinguished from these related species by its smaller female florets and female lemmas that are slightly cucullate at the apex." (Judziewicz & Sepsenwol 2007).
