356 MR. R. A. ROLFE ON THE SELAGINEJE 
Sheet “2” contains one specimen, which I will describe as 
S. CONGESTA, sp. nov.—Perennis, ramulis puberulis; foliis 
fasciculatis subulato-linearibus obtusis levibus; spicis termina- 
libus ovoideis densissimis, bracteis lineari-lanceolatis acutis his- 
pidis; calyce profunde 2-partito (segmento postico deficiente) 
segmentis linearibus obtusis concavis hispidis; corolle tubo 
gracili, segmentis obovato-oblongis tubo dimidio brevioribus ; 
staminibus styloque breviter exsertis. S. fruticosa, Thunb. par- 
tim! non L. 
Ad Cap. b. spei. Thunberg ! 
Frutieulus rigidus. Folia 14-24 lin. longa. Spica 6 lin. longa. 
Bractee 14 lin. longe. Calyx 1 lin. longus. Corolla 2 lin. 
longa. 
S. sPURIA, L.! Sp. Pl. ed. 1, p. 629. Four specimens on two 
sheets. Correct. 
S. rapunculoides, L.! Amoen. Acad. iv. p. 318. Seven speci- 
mens on four sheets. Correct, but only a vigorous form of S. 
SPURIA, Z. 
S. fasciculata, L.! Mant. p.250. Three specimens on one sheet. 
Correct; but S. serrata, Berg., is the older name. 
Hebenstreitia dentata, presumably of Linnzus, but totally 
different. There are four sheets. Sheet “a” contains two dis- 
tinet species. Atthe top of the sheet in the centre is a specimen 
of the plant deseribed by Choisy (in DC. Prodr. xii. p. 16) as 
Selago squarrosa! ; but it isa true Hebenstreitia, and is H. RAMO- 
SISSIMA, Jarosz, Pl. Nov. Cap. p. 14. The remaining four plants, 
as well as six specimens on the three other sheets, are all Choisy's 
Polycenia hebenstreitioides!, the type of a genus founded on the 
presence of lacune in the nutlets, an insufficient character, which 
breaks down in another species. It is H. REPENS, Jarosz, Pl. 
Nov. Cap. p. 15. 
H. ciliata, Berg.! Pl. Cap. p. 154. Four specimens on one 
sheet of DISCHISMA crLrATUM, Choisy. Correct. 
H. corpata, L.! Syst. Nat. ed. 18, ii. p. 420. Two specimens 
on one sheet. Correct. 
Thunberg's * Flora Capensis? (1828) contains only an enume- 
ration of the species of his ‘ Prodromus,’ with the descriptions 
amplified and the localities in many cases added. One additional 
species, however, occurs, viz. :—
