COAST FLOIU OF JAPYGIA, S. TTALT. 5,% r , 



sitis, involucri phyllis unguiformis scariosis fuscis marginibus 

 albomembranaceis apice leviter dentatis costa media in cus- 

 pidem protracta, flosculis purpureis, acheniis albis lineis longitu- 

 dinalibus notatis subpunctatis apice biannulatis, pappo nullo. 

 Tota planta pilis validis moniliformibus ornata. Habitat in 

 rupium fissuris prope Callipolem in Japygia. 



We see by this description that the brown pubescence, the 

 want of pappus, the smooth achenia, the small size of the 

 capitula, and its totally different habit, serve to distinguish it 

 from the typical C. alba, L. 



We will now describe a variety of the large-headed section, 

 which grows on the cliff called theMontagna d'Oronear Otrauto. 

 The plant is a splendid fellow, and will bear with dignity the name 

 of nobilis. 



Centaubea deusta, Ten., var. nobilis, mihi. Aspera fusca, 

 caule robusto rigido anguloso erecto, ramis paucifloris vel uni- 

 floris ; foliis in lacinias mucronatas divisis, radicalibus petiolis 

 dilatatis semiamplexicaulibus, segmentis foliorum late lanceolatis 

 aliquis pinnula unica ad basin ornatis, caulinibus pinnatis seg- 

 mentis lanceolatis, superioribus integris lineari-lanceolatis vel 

 spathulatis, summis sub capitulo magnogloboso sitis. Involucri 

 phyllis membranaceis nitidis ad centrum maculatis inflatis, costa 

 media in cuspidem protracta, flosculis purpureis, acheniis pube- 

 rulis lineis longitudinalibus notatis, pappo pallido-rufescente 

 seriebus interiori et longiori ad achenium sub«quali. Tota plant* 

 pilis validis moniliformibus ornata. Habitat ad rupes Montis 

 Auri prope Hydruntum in Japygia. 



Contrasting these two forms of the deusta section, one cannot 

 help being struck by their divergence in many respects ; thus, 

 one has a long pappus and a pubescent achenium, while the other 

 has a smooth fruit and is quite devoid of pappus, in the place of 

 which one finds two rings, one along the edge and another inside 

 the rim. One is a large robust plant of few branches, while the 

 other is remarkable for the number of them, being even intri- 

 cately corymbose. To give an idea of the variety of these plants, 

 I will mention that I have two forms in my herbarium of the 

 large-headed section from Calabria, one of which has filiform 

 segments to the leaves, and pappus half the Ieugth of the whitish 

 achenium, the capitula being large, but less than the var. nobilis 

 by a great deal. The other is a branched plant with broad seg- 

 ments to the leaves, the uppermost of which have strong triangular
