 basin 2 mm. lat., superne 1 mm. vel etiam minus. Coronae tubus 

 segre 5 mm. long., hujus dentes 1-1-5 mm. long. ; ligulse 4 mm. 

 long. ; ligulge inclusaB 2 mm. long. Columna staminea 1 mm. 

 long. Antherarum alse -5 mm. long., appendices fere 2 mm. long. 

 Pollinia pyriformia, -25 mm. long. Folliculus 12-5 cm. long.,

Differs from F. Lugardi N. E. Br., inter alia, in the small 

 leaves, the distinctly pedicelled flowers, the longer segments of 

 the calyx and the longer corona with different toothing. 



No. 942, of the same collector, also from Victoria, with closer 

 and shorter branching, smaller leaves (2-3-5 cm. x 4-6 mm.), and 

 somewhat reduced flowers, is a plant apparently conspecific with 

 the above, but growing under different conditions. 



' VI. CoNYZA DECURRENS Linn. 



Under Monenteles Pterocaulon A. P. de Candolle " remarks : 

 "An forte Gomjza decurrens Lin. sp. 1206 eadem aut affinis ? " 

 This in spite of the fact that Linnaeus gives India as the locality 

 of his species, whereas M. Pterocaulon was founded on a Mada- 

 gascar plant of Bojer's collecting. LinnjBus's description (/. c.) 

 is short and almost valueless for purposes of identification ; so 

 that but for the fortunate circumstance of there being specimens 

 of C. decurrens in the Linnean herbarium at Burlington House, 

 no answer to de CandoUe's query would be possible. Examination 

 with Dr. B. D. Jackson's kind help of the Linnean material showed 

 C. decurrens to be conspecific with an unnamed Pterocaulon in 

 the National Herbarium collected by Bojer : this latter is without 

 locality, the only note accompanying the specimens being to the 

 effect that its Madagascar name is " Ari-androo-vavi." 



It now became necessary to ascertain whether Bojer's speci- 

 mens just mentioned were referable to Monenteles Pterocaulon DC. 

 I therefore forwarded to M. Casimir de Candolle a small scrap, 

 together with a photograph of the sheet of Bojer's specimens 

 taken by Mr. D. A. Rendle, with a request to that gentleman that 

 he would kindly compare this material with the type of M. Ptero-
