or prefixed to P. jlorida : but the distinct leafstalks and want of 
silky villosity incline the scale in favour of the first alternative. 
L. glaucus Sol. MSS. in BH., and therefore of Ait. Hort. Kew., 
was established on two ex. without fl. but in fr. of the Madeiran 
pi. on a single sheet marked by Solander himself u Lotus glaucus 
(3, 1. Madeira prope Funchal J. B. and DS. 1768/’ and “2 Ma- 
deira prope Ponta Sad Lourenzo, Fr. Masson 1777.” In the 1st 
of these the 1. are all nearly or quite sessile ; in the 2nd some of 
them are shortly stalked (petioles J—l line long). Hence in his 
diagnosis Sol. says “foliis sessilibus;” whilst in his description 
occur the words “brevissime petiolata.” Hence also Webb’s 
wrong reference of “L. glaucus (3. Soland. ! MSS. in herb. Banks.” 
(Phyt. ii. 85) to the very distinct Tenerifan L. sessilifolius DC. : 
for no. 1 on this sheet is assuredly (strictly speaking) Solander’s 
original type of L. glaucus , and notwithstanding the altogether 
sessile 1. =the common Madeiran pi., no. 2, with which in fact 
Solander has associated it. 
Another sheet in BH. contains two ex. marked also by Solan- 
der “ Lotus glaucus MSS. a., 1. Madera F. Masson 1776 (juxta 
ponta de Crux),” and “2. Ins. Canar.TeneriffaFr. Masson 1778.” 
Of these the 1st (which is in fl. and fr.) accords exactly with the 
2nd of the two ex. on the former sheet in having some few of 
the 1. similarly stalked ; and perhaps this was the cause of Solan- 
der marking it with an a. as varietally differing from one at least 
of the two above-named spec, marked /3 ; though in his MSS. he 
does not preserve, or indeed notice such distinction ; rather in- 
dicating by certain corrections in them a sense of its futility. 
The Tenerifan spec. (Masson 1778) on this sheet (in fl. only) is 
a mere fragment in bad condition ; but it probably belongs to 
the very distinct Pedrosia tenella Lowe. 
There exists yet a 3rd sheet in BH. marked by Solander u Lotus 
corniculatus Linn, variet. Madera Francis Masson 1776,” but 
which I believe to be precisely identical with his L. glaucus as 
above explained and exemplified. Some of the 1. have petioles 
1 line long. This possibly occasioned its reference by Solander 
to L. cornicidatus, as being rather in his judgment identical with 
the Madeiran pi. on two other sheets so-called by him ( Pedrosia 
neglecta Lowe), than with his L. glaucus , before he had aban- 
doned his first idea of the latter being characterized by having 
uniformly sessile leaves.
