386 NOTES ON SPECIES OF LOTUS § PEDEOSIA. 



much less forward direction assumed by the lateral leaflets. From 

 L. arenarius it differs by the shape of the stipules, the much 

 smaller leaves, aud by its biennial (? subperenuial) duration. 

 Nevertheless several authors (Webb, Masferrer, Colmeiro) agree in 

 thinking that it is almost too closely allied, and may perhaps be 

 only of subspecific rank. For the present, however, it seems better 

 to retain it as distinct. 



Bourgeau's L. holosericeus of PI. Can. 1325 is, judging from my 

 specimen, really L. campylodadus. It was collected in Tenerife 

 (Cahadas del Teyde, in rupibus). I collected it, once only, among 

 loose pumice above Guimar in the same island at about -iSOO ft. 



Lotus holosericeus Webb & Berth. One of the most striking 

 aud distinct of the group. Probably quite confined to Gran Canaria, 

 and extremely local even there. The type specimens were found 

 near Mogan, and I have collected it iu the same neighbourhood, 

 and also near Tiraxaua. This would give a range of 2000-3U00 ft. 

 above sea-level. 



This species may be easily known from L. campyhwladus by its 

 more erect habit, by the very beautiful silky-viilose clothing of the 

 whole plant, and by the stipules similar to the leaflets. The 

 lateral leaflets are markedly assurgent, i.e. lying almost close to 

 the terminal leaflet, instead of spreading at right angles. Webb 

 notes: "Foliola inferiora petiolata, superiora subsessilia." 



In herb. Webb a plant from Palma (Caldera) is labelled L. 

 holosericeus ; I have no note about it, but have little doubt that it 

 is really L. arenarius. And in herb. Schinz there is a specimen 

 from S. Juan de la Kambla in Tenerife also labelled L. holosericeus. 

 Unless my memory deceives me, it really belongs to an aberrant 

 form of L. sessilifolius, which I have myself collected in the same 

 locaHty. 



Lotus spartioides Webb & Berth. This species, like the last, 

 is confined to Gran Canaria, where it seems to be exceedingly rare. 

 I have only once seen it ; on the mountain side near Artenara, at 

 above 4000 ft. It formed a large patch, several feet across, and 

 being in full flower was conspicuous at a distance of nearly a 

 quarter of a mile. 



Very distinct from every other species ; it is recognizable at 

 once by its shrubby habit, distinctly stalked leaves, linear leaflets 

 and stipules, lateral leaflets forming an acute angle with the 

 terminal, long peduncles, furnished with an inconspicuous, often 

 unifoliate, floral bract, and linear-lanceolate setaceous calyx teeth. 



Lotus argyrodes, I venture to propose this name for the Porto 

 Santo and Madeira plant described by Lowe (Hook. J. Bot. viii, 

 293) under the name of Pedrosia artjentea [Lotus argenteus Masferrer, 

 1880). Unfortunately this name had been already used to designate 

 an Egyptian and totally different species, viz. Lotus an/enteus Webb & 

 Berth. = L)ori/c)uu)n argenteum Delile. A new name is therefore 

 necessary. 



The range of the species is somewhat peculiar. It occurs (but 

 rarely) along a line of somewhat over thirty miles from Porto Santo 

 to the Desertas, just touching the extreme eastern point of Madeira
