188 HORN EXPEDITION — BOTANY. 



smooth, lanceolate-oval to oval-oblong, about twice as long as sepals. Pod oblong, 

 flat, obtuse, one and half inches long by one-quarter or three-eights wide ; valves 

 membranous. Seeds about six, transverse, thick, depressedly orbicular to oval- 

 oblong, impressed above and below ; estrophiolate ; funicle short, once or twice 

 folded under the seed. 



This species in its foliage, flowers and fruit approaches A. leptopetala, but 

 seems to differ by more distinct neuration of the phyllodia, by its tetrauierous 

 flowers and flattened seeds. It has some affinity with A. seniis, but the seeds are 

 not globose, and stipules are absent. 



DiDiscus GiLLEN^, Tate. 



Herbaceous, apparently annual, acaulescent with radical erect leaves and 

 decuaibent simple peduncles, spreading to one or two feet; when dwarf the peduncle 

 is erect. Leaves on long petioles, deeply five-lobed with cuneate three- or flve-lobed 

 divisions, sparsely covered with long soft hairs. 



Peduncles two or three times exceeding the leaves, simple; umbel of numerous 

 flowers on relatively long pedicles. Involucral bracts herbaceous, linear-lanceolate 

 with setiferous tips and margins, as long as the flowers and distinctly united at 

 the base. 



Flower-head 10 to 20 mm. diameter; flowers very numerous on slender 

 pedicles of 5 or more mm. long, calyx tube red ; petals whitish above and pink 

 beneath ; anthers red. 



Fruiting pedicels exceeding the involucral bracts ; carpels slightly laterally 

 compressed, densely covered with simple bristly pinkish-red hairs having a 

 thickened base ; one carpel usually larger than the other, oval, about 2 mm. 

 high and less in width ; seed slightly compressed. 



In its bristly carpels this new species resembles D. cyanopetala from which it 

 differs in denser umbels, well-developed pedicels, longer leaf-stalks, colour of flowers 

 and carpels. 



The dedication is a slight mark of tribute to Mrs. F. J. Gillen's hospitality, 

 which was enjoyed by the author and other members of the Expedition. 



Wedelia Stiklingi, Tate. 



Erect, rigid, often two feet high. Leaves linear-lanc(;olate, acuminate, toothed. 

 Peduncles rigid, up to six inches long, solitary. Involucres hemispherical, about
