Umbilicus citrinus, sp. nov. (^ CotyleI. {U. penduUnus DC. 

 var. bracteosus Willk. in Willk. & Lange, Prodr. Fl. Hisp. Suppl. 

 p. 213.) Herl)a caule circa 0-5 m., foliis raclicalibus peltatis, longe 



petiolatis, caulinis ; racemis secundis, circa 15 dec. longis, 



floribus horizontalibus vel pendulis, pedicellis 2-5-3 mm., bracteis 

 hyalinis, pedicellis duplo longioribus, calicis lobis triangulari- 

 bus acutis, vix 2 mm. longis, corolla flava, 9-12 mm. longa, 

 cylindrica, sub lobis contracta, lobis ovato-lanceolatis, nervo 

 valido excurrente notatis, carpellis corollas tubo duplo breviori- 

 bus, antherarum basin vix attingentibus, antheris filamentis 

 longioribus. 



Differs both from U. korizontalis DC. and U. penduUnus DC. 

 in being taller, in its secund racemes of longer bright yellow 

 flowers, the corolla-tube constricted below the longer broader 

 lobes, and in its much shorter carpels. 



It grows sparingly by the Almoraima Soto (No. 2127), and in 

 a neighbouring valley near Long Stables. Eeverchon's No. 571 

 from shady woods near Grazalema also belongs here. 



Umbilicus pendulinus DC. var. truncatus, var. nov. Herba 

 foliis omnibus basi truncatis vel subcordatis, profundius lobatis, 

 petiolis lateralibus. 



The cauline leaves of this species are frequently laterally 

 petioled, but in the variety even the lowest radical have that 

 peculiarity. 



On roofs of houses in Palmones Village (No. 751). 



Sbdum Winkleei, comb. nov. (S. liirsutum subsp. hceticum 

 Kouy. Umbilicus Winkleri Willk.) Specimens sent to Willkomm 

 by Winkler, from the S. Carbonera were described by him as 

 Umbilicus Winkleri in Act. Soc. Bot. Germ. 1883, p. 268, and 

 figured in 111. Fl. Hisp. i. pi. 74 a. Later, in 1887, Eouy, in 

 Bull. Soc. Bot. Fr. xxxiv. p. 441, described a subspecies bceticum 

 of Sedum liirsutum All., based upon specimens sent from the 

 S. de Palma by Eeverchon, differing from the type in being larger, 

 more glandular, leaves longer, and flowers twice the size. 



I have seen no specimens from either collector, but one 

 collected by Porta and Rigo on the S. Carbonera, labelled Umbi- 

 licus Winkleri Willk., and plants seen there, as well as on the 

 Alcadeza Crags and in the S. de Palma, agree exactly with 

 Willkomm's figure and description, as well as that of Eouy, and 

 I have little doubt that both authors have described the same 

 species. Eouy, however, has overlooked the important feature of 

 the plant — that the petals are united at the base for about one- 

 third of their length, instead of at the base only — which doubtless 

 caused Willkomm to place it in Umbilicus, but as this character 

 is variable in Sedum, and the plant so closely resembles a large 

 variety of S. liirsutum, I propose to keep it in the genus under 

 the name given above. 



It grows in considerable quantity on rather damp rocks on the 

 summit of the S. Carbonera (No. 1293), in the Waterfall Valley 

 in the S. de Palma, and on the x\lcadeza Crags. Specimens
