Ab Abolboda pulchella H. B., cui habitu subsimilis, foliis 
longioribus, stigmatibus irregulariter laceratis, lobis corollee 
imberbibus etc. — ab ÅA. vaginata (NPRENG.) ALB. NILSs. foliis 
multo longioribus, appendicibus styli, spica magis pauciflora, 
anatomia radicum foliorumque etc. differt. 
Wie es aus den FErörterungen ALB. NILSSONS hervorgeht, der 
Abolboda vaginata (SPRENG.) zu untersuchen Gelegenheit hatte, weicht 
diese Gattung in vielen Hinsichten von Xyris anatomisch ab. Meine
