Montevideo " (Gaudichaud in Herb. Berql. ; Arsene Isabelle in Herb. 
Paris.) gives us a clue to Iiis reason.' He has seen those specimens 
and doubtless found them to agree with L. marinnm^ and Montevideo 
being on the same coast as Maldonado, be believed that he bad found 
Cambessedes' plant. I conclude, from Kindberg not liaving noticed 
it, that there is no specimen of the plant found at Maldonado in the 
herbarium of the Museum at Paris. If we turn to the plate in the 
* Flora BrasiLj' it is difficult to see on what grounds it can be supposed 
to represent any state of X. marinnm. Its remarkably long subuhite, 
vather closely placed leaves, and very long triangular stipules, are 
greatly dissimilar from those parts of L. maiimim. It probably is a dis- 
tinct species from any of our European plants. Steudel (Nomencl. 123) 
combines the plant of Cambessjdes with the Jrenaria Bonajnensis^ Gill, 
(in Hook. Bot. Misc. iii. 148), but the latter plant is stated to have 
"foliis lineari-filiformibus . . . internodio brerioribus" and " caulibus 
remote foliosis," and therefore their union is probably erroneous. 
Steudel also locates the compound species at '* Bonaria, New Holland," 
whereas Cambessedes' plant is Brasillan, and that of Gillies grew at 
Bu-nos Ayres. This conjunction brought about by Steudel has caused 
some authors to believe that the Brasilian plant has no claim to the 
name Lepig. or Sperg. rupestris, but would in future answer to that of 
Z. Bonariense, It will have been seen that sucli is far from beino- the 
fact, and that the name X. rupestre is its property, and therefore the 
European plant cannot be so called. Lebel gave the alternative of ru- 
pedns or rupicola ; we therefore now^ take the latter, and call our plant 
Z. rnpicoJa. It is unfortunate that Kindbea'g should have used the in- 
admissible alternative, for authors of recent date have naturally followed 
him, and some confusion is thereby introduced. It should be stated 
that Lebel never described his plant, and that we might therefore have 
given a totally new name to it, if inclined to aspire to such a question- 
able honour.
