Campbell's Islands.] FLORA ANTARCTICA. 29 



as many arches as there are nerves, apparently without reference to the number of teeth of the corolla, in the 

 thickened substance of which they are entirely lost. Amongst the discoid groups of Senecionidea, there are many 

 anomalous structures of the female corollas. Thus, in Stromjylosperma, Less., the limb of that organ is reduced 

 apparently to a very short tube, completely continuous with the achaenium ; and one of the principal characters 

 of SoUva, R. and Pav., consists " in the want of corolla or" (as Mr. Brown remarks) " perhaps its accretion 

 with the persistent style" (vide Linn. Trans, vol. xii. p. 101). The original species, L. scariosa, Cass., was 

 transmitted alive to England from Cape Horn, and is now cultivated in the Royal Botanic Gardens at Kew, 

 where it blossoms copiously, and as it increases rapidly and has been widely distributed, I hope that the atten- 

 tion of microscopic observers will be directed to the singular structure of its flowers. Though possessed of no 

 beauty, it derives an interest from being one of the most Antarctic flowering plants. 



The glands, so conspicuous in this and some of the other species , appear to be conglobate and formed of about 

 four very prominent papillae, confluent at their margins; in this species and in L. scariosa they are transparent, 

 but in L. lanata, after drying, they turn opake and whitish. I observed that in the fresh state they contained 

 no evident secretion or essential oil, nor can they be connected in any way with the peculiar odour which several 

 of the species possess, as this is inodorous or nearly so, and L. plumosa, which smells strongly, is unprovided 

 with these organs.
