As regards var. grandifolia matters are different. The plant so 
named here is the plant which Willdenow mistook for @. poly-

that after all the two are but varieties of one species, but there is 
no doubt that ‘hey are valid varieties. It should be noted that 
while ee supposed the larger leafed variety to be C. poly- 
gonoides, Krauss supposed—equally erroneously, it is trae—that the 
ciaflar leafed plant deserved that name. 
maining variety, here termed tenuifolia, may, as the 
result of further field-study, prove to be specifically distinct from 
C. rubricaulis. It includes three quite readily distinguishable 
forms : (a) with long, narrow, linear leaves subinvolute towards the 
base = C. tenuifolia, Sond. non Willd. ; (6) with linear-lanceolate 
leaves ses hoes towards the base = C. thymifolia, Willd. 
M nd (c) with short ovate-lanceolate leaves quite flat along 
the raise throughout = C. imbricata, E. Mey., b not a. This 
last differs mainly from the true C. ee EK. Mey., a no Seas in

a variety of C. pabnicaate aiderng from the type of that species in 
having internodes as long as, in place of much shorter than the 
leaves ; or that it is only a variety of C. africana with much smaller 
leaves quite flat at the margin. Which of the two positions may 
prove the more satisfactory it is, with the material at our disposal, 
as yet impossible to say. Baillon in 1862 hazarded the suggestion 
that C. ovalis may not be a Cluytia at all; for this guess there is 
no justification. The ori iginal type of the species is in herb. 
Holm. ; 3 it matches exactly ‘Schlechter 4966’ which Pax has 
placed in C. Alaternoides [3 genuina, and identified with Miiller’s 
form elliptica—a plant which C. ovalis, Sond., does not closely 
mean or readily recall.
