DIMORPHISM IN ERANTHEMUM. 
By Joun Scorr. 
At pages 46 and 47 of the aga of Botany,’ I observe that Mr. 
Kurz has INI anticipated me in a communication which I have had 
long in dimorphie Daido I am only surprised to learn 
that Mr. nis ~ himself been unaware of the existence of dimorphism 
in : 
Anderson had similarly omisi these by no means inconspicuous 
phenomena, steui as it was he who rid directed má arena! iw 
them. This was early in 1866, on his return from a visit to Moulm 
Where, if I mistake not, the Rev. Mr. shpine and he had first iinet 
the phenomena i in F. cinnabarinum; and on many subsequent occasions 
did he and I examine the flowers of that and wrt similarly characterized 
species on the living specimens in the Botanic Gardens. In his list of 
Acanthaceæ cultivated in the gardens here, and printed in the Journal 
of the Agri.-Hort. Society of India, 1869, page 286, he remarks under 
e 1 
FE. cinnabarinum that e large conspicuous flowers are quite sterile, 
seeds are produced only by small deformed flowers in which the limb 
of the corolla is almost degens These flowers are not commonly e - 
ciem in [baee dec Hs. before he exami urm 
species, it is a mystery to me how he should have cst the fact 
in examining an apparent form of the variabl ulatum, a d s 
Lo Su upposing, on the other hand, that Dr. Anderson, unaware of the 
existence of the roy rns peculiarity i in any other agar had found 
pecimens uniformly characterized by the minute flowers only, he might 
well have discarded it from Zranthemum, an d aken it even as the repre- 
sentative of a new genus, oue which assuredly would thus have had con- 
siderably better claim to acceptance e than cou re be shown, for gern in
