25. LEGUMINOS^:. 
Webb, having sent me from Orotava in 1829 a single spec, of 
the true L. glaucus Ait. a. intricata , has subsequently confoimded 
with it two very distinct and hitherto undescribed sp., P. tenella 
and P. leptophytta Lowe, the last of which he has also unfor- 
tunately figured (Phyt. Can. t. 61) for the true “ L. glaucus Ilort. 
Kew.,” and again probably at t. 60 for the trueP. sessilifolius DC., 
a not uncommon pi. in Tenerife (near S ta Cruz and Guimar), but 
very unlike his t. 60. This confusion is completely proved by 
his and Bourgeau’s spec, sent as “ L. glaucus Ait.” “ or Hort. 
Kew.” in BH. and HH., which all belong either to P leptopliylla 
or P. tenella. The true L. glaucus Ait. I was myself unable to 
discover anywhere in Tenerife; and indeed in all the Canary 
Islands I only once met with a single pi. of it on the W. coast 
of Fuerteventura on the remote desert shore of the Plaga Biocho. 
The spec, however from Webb of true L. glaucus Ait. above re- 
ferred to as sent to me by him in 1829, appears from his accom- 
panying letter, dated Orotava, to have been collected by him on 
the W. coast of Tenerife, on which during a six months’ residence 
near Orotava, and in shorter subsequent visits, I could myself 
find nothing but P. tenella. This sp. indeed, abounding all along 
the W. coast of Tenerife from Orotava to Garachico, must be 
assuredly the pi. intended by Webb under his L. glaucus by the 
words “In rupibus maritimis Teneriffse occidentalis copiosa.” 
His other localities for L. glaucus between Las Palmas and Telde 
in Gr. Canary, I have never visited : but the common Gr. Cana- 
rian sp. on barren hills above Las Palmas to the N. is P. lepto- 
phylla Lowe. 
The nearest approach to the true L. glaucus Ait. exhibited by 
any spec, from Webb or Bourgeau in IIII. or BII. is presented 
in 3 sheets or sets of spec, from Tenerife named L. dumetorum 
Webb MSS., but not described or alluded to in liis ‘Phytograpliia 
Can.’ They are no. 803 of Bourgeau’s first (1846) and nos. 1321 
and 1322 of his second (1855) Tenerife collections: and though 
I cannot at all assent to their supposed affinity to L. arenarius 
Brot., indicated by the words u L. arenarius Brot. var.P” appended 
to the name L. dumetorum Webb MSS. in nos. 1321 and 1322, 
there seems less objection to their being regarded as extremely 
luxuriant or robust states or var. of L. glaucus Ait. ; though at 
present I am more inclined to consider them with Webb as con- 
stituting a distinct and undescribed sp.
