Ornithogalum refractum, var. Adalgisa, mihi. — An Ornithoga- 

 lum which occurs sparingly in the neighbourhood of Otranto, and 

 occupies a place between O. refractum, "Walds. & Kit., and O. ai- 

 vergens, Boreau ; resembling the former in the refraction of its 

 fruit-peduncles, while it shows the large flowers and horizontal 

 flower-peduncles of the latter. The flowers are usually few in 

 number, rarely more than five, and more frequently three ; thus 

 forming a contrast to the normal species, which usually shows a 

 larger number of smaller blossoms. O. exscapum, Ten., is a 

 much smaller plant, and has not the proliferous bulb of the species 

 under notice ; which, moreover, in fruit has its peduncles closely 

 adpressed to the scape ; for which reason I have decided to 

 attach it to O. refractum, although it differs exceedingly from that 

 species in other particulars, as I have just shown. I append a 

 description taken from a fresh specimen. 



Obnithogaltjm befbacttjm, var. Adalgisa, mihi ; corymbo 

 paucifloro, floribus speciosis fere tribus raro pluribus, pedunculis 

 floriferis divaricatis, fructiferis refractis scapo applicatis, fructu 

 adscendente, bracteis lanceolatis acutis pedunculo quarto brevio- 

 ribus, phyllis perigonii late lanceolatis obtusis, stamiuibus peri- 

 gonii dimidium sequantibus, foliis late linearibus subacutis 

 arcuatis stria media albula notatis, bulbo prolifero. 



A similar plant was sent to me from Monte Collai, near Pola ; 

 growing also on calcareous soil, at a height of about 30 feet, 

 which is at about the same level as our specimens. 



Phleum grcecum, Boiss. — There is also a variety of this with a 

 tendency to P. arcnarium, L. 



AZgilops uniaristata, Vis. 



We have now come to the last of our divisions, that of Local 

 Species and varieties. These are necessarily few, as the district 

 is not an extensive one ; but the consequent rarity of the plants 

 will compensate for their restricted numbers. 



Alyssum leucadeum, G-uss. — For many years this species seems 

 to have given the slip to its eager searchers. I now have it 

 from Otranto, where it is very scarce, growing on the Montagna 

 d'Oro, one of the sea-cliffs; and from Gallipoli, where it is 

 extremely abundant, and although it begins to flower in 

 January, I have found it blossoming in June. It is a handsome 

 plant of a pleasing genus ; but I have a suspicion that it and 

 A. gemonense, L., are varieties of one species. I have never seen 

 the latter growing ; but judging from herbarium specimens,
