Thus there does not appear to be any justification for 
the above segregations from the variable 4. fimbriata, a 
species which appears to show many gradations in the 
form of the lip from suborbicular to round-ovate or 
round-elliptic. 
Altensteinia marginata Reichenbach filius Xen. 
Orch. 8 (1878) 20.

A careful comparison of these two concepts, as rep- 
resented by records of the types as well as by the descrip- 
tions, indicate that they are conspecific. 
The only discrepancies appear to be that 4.margin- 
ata shows somewhat broader leaves than those of the type 
of Prescottia pteristyloides, and that the latter concept is 
noted as having narrowly lanceolate 1-nerved_ lateral 
sepals, whereas the lateral sepals of 4.marginata are de- 
scribed as oblong and 8-nerved and are drawn as elliptic- 
lanceolate and 3-nerved. Both species came from regions 
of the same altitude.

Judging from habit and analytical drawings of A/ten- 
steinia Matthewsii trom the Reichenbach Herbarium in 
Vienna as well as from a specimen of that species iden- 
tified by Reichenbach, it seems unwise to segregate from 
it the concept Aa Lechleri. Indeed the only discrepancy
