480 POLYGONACE& (Wright). | Rumen. 
Kataunart Recion: Transvaal ; near Lydenberg, Wilms, 1276 ! 
Also in Europe, Western Asia ; introduced into North America. 
19. R. conglomeratus (Murr. Prodr. Stirp. Geett. 52) ; a perennial ; 
stem up to 4 ft. high, simple or slightly branched, glabrous ; 
leaves oblong-lanceolate, subacute, rounded or cordate at the base, 
irregularly crenate, 8 in. long, 2 in. wide, petioled ; panicle 
terminal, more or less leafy, branches spreading ; whorls many- 
flowered, distinct ; pedicels slender, jointed below the middle ; 
inner perianth-segments linear-oblong in fruit, subacute, quite 
entire, with oblong warts on the back. Meisn. in Linnea, xiv. 492, 
and in DC. Prodr. xiv. 49. R. Nemolapathum, Ehrh, Beitr. i. 181; 
Meisn. in Linnea, l.c., not of Wallr. 
Sourn Arrica: without locality, Drege. 
Coast Recion: Cape Diy. ; Kenilworth, near Cape Town, 100 ft., Bolus, 7039 ! 
Kloof below Constantia Nek, Wolley-Dod, 2425! Paarl, ex Meisner. 
Also in Europe, North Africa and Western Asia; introduced into North 
America. 
Imperfectly known spectes. 
20. R. lanceolatus (Thunb. Prodr. 67); stem erect, 2 ft. high, 
branched, rather flexuous, sulcate, glabrous ; leaves lanceolate, 
acute, rounded or shortly attenuate at the base, about 6 in. long, 
margins reflexed, very slightly crisped, glabrous, petiolate ; racemes 
terminal and axillary, solitary, undivided, slender, interrupted at 
the base ; whorls 3-8-flowered ; pedicels 2-3 times as long as the 
perianth, jointed above the middle ; inner perianth-segments ovate- 
oblong, suddenly narrowed at the middle into a ligulate point, 
entire; fruit unknown. Thunb. Fl. Cap. ed. Schult. 340 ; 
Campderd, Monogr. Rum. 148 ; Meisn. in Linnea, xiv. 493, and in 
DC. Prodr. xiv. 50. 
Sourn Arrica : without locality, Thunbery, Drége. 
An imperfectly known species. A plant collected in South Africa by Wallich 
agrees in many respects with it, but its perianth-segments are not suddenly con- 
tracted at the middle. Also one collected in Natal, near Pietermaritzburg by 
Wilms (2243c). A similar plant was collected at Genadendal, Caledon Div., by 
Alexander Prior. 
21. R. spathulatus (Thunb. Prodr. 67); stem erect, striate, 
glabrous, purple, about 1 ft. high ; branches few ; leaves obovate, 
obtuse, the upper lanceolate, erecto-patent, 1 in. long ; petiole a 
little shorter than the blade; flowers verticillate, erect ; inner 
perianth-segments warted. Thunb. Fl. Cap. ed. Schult. 340; Meisn. 
in DC. Prodr. xiv. 50. 
Souru Arrica: without locality, ex Zhunberg. 
A very imperfectly known species which Meisner suggests may be the same as 
R. Meyeri, Meisn.
