25. LEGUMINOSJE. 
large campanulate 5-fid, its teetli 3 times the length of its tube 
linear equal erect or ascending villose nearly as long as the fl. 
Cor. rather small scarcely exceeding the cal. ; standard and 
wings blackish purple shorter than the narrow acuminate keel 
which is greenish lemon-col. more or less black or streaked with 
black. Stamens diadelphous 91. Style smooth upwards with 
a short straight fork or tooth below the distinctly capitate 
stigma. Pods most like those of P. glaaca but only in. long 
and 1 line broad, often shorter than the sep. and concealed 
within the cal., clothed like the cal. with thick w. shaggy hairs, 
strongly moniliform or strangulate, divided internally by com- 
plete transverse septa into as many distinct cells as there are 
seeds or turgid globose joints, not however separating across 
between the joints but bursting as usual longitudinally into two 
valves, each divided into cells by the halves of the septa which 
split each into two parts. Seeds ovahglobose brown quite 
smooth and even. 
Exclusively, apparently, a Porto-Santan pi., discovered first 
in 1828 in company with Webb, but laid aside for many years 
in order to establish, by comparison with other cognate genera 
and sp., the claims to generic distinction from Lotus which, 
from the first, I believed it to possess. 
Scarcely three months after its publication (Oct. 1856) under 
the name of P. Porto-saneta?ia in the J. of Bot. seeing for the 
first time a copy of vols. ii. and iii. of Webb’s Phytogr. Can., it 
was at once apparent that the pi. had been previously described 
from PS. specimens, gathered with me in 1828, under the name 
of Lotus ( Heinekenia ) Loweanus , by the excellent and amiable 
author of the 1 Canarian Flora.’ His specific name possesses 
therefore a clear right of priority. I only regret unfeignedly 
that Heinekenia has no such claim for adoption, having been 
imposed by him on an illconstituted section merely of Lotus, 
embracing only one (the present) true Pedrosia, and not being 
in any way correlative with that generic group, to which indeed 
his other section, Etymolotus, rather corresponds, though not 
defined by any clear invariable or important character.
