3 F. STRI'CTA (Lodd. bot. cab. 't. 1219.) the figure and de- 

 scription of this plant are so insufficient, as not to admit of us 

 giving a description of it ; and the plant is now lost in the gar- 

 dens. 57 . G. Native of New Holland. 



Straight Fabricia. Fl. April, Ju. Clt. 1827. Sh. 2 to 4 ft. 



Cult. The species of Fabricia are well fitted for a conserv- 

 atory, as they do not flower until they have attained a consider- 

 able size. A mixture of loam and peat is the best soil for them. 

 Cuttings taken from young wood root readily, if planted in a 

 pot of sand, with a bell-glass placed over them.

 sule 2-5-celled, many-seeded, inclosed in the calyx. Shrubs,
