 of the western U.S., the Steppes, &c. 4 Brit, (wormwood). A. tri- 

 dentata Nutt. and others form the halophytic ' sage-brush ' of the 

 S.W. U.S. Fl. -heads small, inconspic., and w/a?fert. (cf. Poterium, 

 Rheum and Rumex, Plantago, Thalictrum, &c.). In A. vulgaris L. 

 the marginal florets ?, the rest g. Head pend. ; the anther-tube 

 projects beyond the C so that the dry powdery pollen is exposed to 

 the wind. On the tips of the anthers are long bristles which together 

 form a temporary pollen-holder. Afterwards the style emerges and 

 the large hairy stigmas spread out. An interesting case of reacqui- 

 sition of a character not found in most higher flowering pi. A. Abro- 

 tanum L. (old man, southernwood), and others, cult. orn. 11. The 

 flavouring matter of absinthe is derived from wormwood.

Artocarpus Forst. Moraceae (11). 60 Indomal., China. Many show 

 good bud-protection by slips. A. laciniata Hort. has large drip-tips 

 (Acer, Ficus). Fls. monoec., the 3 in pseudo-catkins, the ? in pseudo- 

 heads. A multiple fr. is formed, the achenes being surrounded by 

 the fleshy P and the common receptacle also becoming fleshy. The 

 fr. contains much starch &c. and is a valuable food-stuff. Several sp. 

 are cult, all over the trop., e.g. A. incisa L. (bread-fruit) and A. inte- 

 grifolia L. (jak). The flesh has somewhat the texture of bread and 

 is often roasted. The best cult, forms (cf. pear, banana, &c.) produce 

 no seeds. The jak and others are cauliflural. Timber useful.
