Leaves mostly opposite. Plant pubescent, by characteristic 

 hammer-shaped hairs (Fig. 20). SufTrutescent ; in No. 328 there are 

 long dead shoot-systems, and the year-shoots 

 are only about 5 cm long. Tn No. 343 they 

 attain a length of 15 — 20 cm. Both bear 

 young fruits and single ripe ones.

5. (?) A. stipitatum Benth. Fl. Austr. V 



(1870) 168. 



The specimens collected being male 

 only, they are not discernible from A. Mo- 

 quiniana Web., which species according to 

 Bentham differs from A. stipitatum by its fruiting bracteoles. 



Male clusters in open spikes. Flowers yet unopened.

6. A. rhagodioides F. v. Müll., Benth. Fl. Austr. V (1870) 172. 

 Of this frutescent and mealy-white species two specimens are 



present in the collection. The first, No. 346, is a female specimen 

 without any male flowers, but whith numerous fruits clustered 

 along the branches. The bracteoles are without dorsal appendages, 

 thickened to the top or nearly so, a narrow strip of thin tissue 

 being sometimes left. The outline varies from rhomboid to nearly 

 semiorbicular and broader than long ; a medial point or blunt 

 angle is always present. Width of bracteoles about 5 — 6 mm. — 

 Most of leaves in this plant are hastate-lanceolate, but entire 

 ones are also found. 



The second plant, No. 347, is male, nevertheless some few 

 fruits are found. The male flower-clusters are terminal, globular; 

 only on the main shoots more are combined, so as to form some- 

 thing like a spike or panicle. — The leaves are lanceolate and 

 entire, only the uppermost ones are angular below.
