large irregular corollas, while S. spuria, L., represents a weaker 
state from younger plants with smaller and more regular co- 
rollas; both the preceding have usually white or pale lilac 
corollas; but Burchell says of one specimen, “ Flores purpurei." 
Of S. coccinea, L., I have not seen an authentic specimen, though, 
as he says, “ Simillima Selag. rapunculoidi,” and “ Flores satura- 
tissime purpurei," there is not the slightest doubt what the'plant 
is, and that Meyer's specimen! represents the true plant of 
Linnsus. Thus the flowers of S. spuria, L., vary between white 
and purple, and the forms cannot be kept up as varieties. S. he- 
terophylla, Thunb.! is a very young seedling of the same species, 
with the large basal leaves which are only present in young 
Specimens. 
S. dubia, L.! One specimen. Founded on Burm. Afric. 
p. 130, t. 47. fig. 3, and Pluk. Mant. p. 180, t. 445. fig. 6! and 
correctly understood. It is Eranthemum angustifolium, Murr.! 
and AGATHELPIS ANGUSTIFOLIA, Choisy ! 
LI 
HEBENSTREITIA DENTATA, L.! In the Linnean Herbarium are 
three sheets pinned together; sheet 1 contains one specimen, 
and sheet 2 one specimen on the left-hand side, of the true 
plant. Both are correctly labelled by Linnsus. On the right 
hand of this second sheet is a small specimen of H. ciliata, 
Berg.!, which Linnzus failed to distinguish. Sheet 3 contains 
two branches from the inflorescence of Selago spuria, L.; but 
there is no name attached. The species was founded on Com- 
melyn, Hort. Amst. ii. p. 217, t. 109, and Burm. Afr. p. 114, t. 42. 
fig. 2, and is correctly understood by authors. 
H. iwTEGRIFOLIA, L. No specimen. It was founded on H. 
foliis integerrimis, L. Hort. Cliff. p. 497, &c. Linnzus points 
out that it differs from his other species, which has “ Foliis 
alternis, acuminatis, aliquot minimis dentieulis notatis; flores 
alternos, bracteis subulatis," by its “ Folia fert linearia, obtusiora, 
nune opposita, nune stellata, foliolis multis ex alis, integerrima. 
Florum spice laxæ; floribus oppositis, bracteis ovatis." This 
constitutes our sole knowledge of the species, as there is no 
specimen preserved from Cliffort’s garden in the British Museum, 
but only one of H. dentata, L. But the above differences point 
distinetly to the plant afterwards described by Thunberg (Prodr. 
Pl Cap. p. 103) as H. scabra!, and later by Andrews (Bot.
