2. C. viscidula (viscid), Wall.; DC. Prod. v. 388 ; Bentli. Ft. Austr. iii. 



496. A tall, branching erect herb, more or less viscid-pubescent, especially the 

 inflorescence. Lower leaves ovate, acuminate, often 3 to 4in. long, upper ones 

 smaller, ovate-lanceolate or lanceolate, all narrowed to the base but scarcely 

 petiolate, slightly toothed or entire. Flower-heads numerous, rather small, 

 clustered and corymbose on the lateral branches of a large terminal panicle. 

 Involucral bracts nearly equal, about 2 lines long, the outer ones linear-lanceolate, 

 acute, the inner narrower, more acuminate, and more scarious. Pappus slightly 

 exceeding the involucre. Ray-florets exceedingly numerous, the style about as 

 long as the pappus, the filiform corollas very much shorter ; disk-florets about

Hab.: Shoalwater Bay, R. Brown. 



The species is common in India. It has much the aspect of Blumea balsamifera, DC, but 

 differs both in involucre and anthers. 



3. C. segyptiaca (Egyptian), Ait..; DC. Prod. v. 382 ; Benth. Ft. Austr. iii. 



497. A coarse, erect, hirsute annual or biennial, sometimes 2 to 3ft. high and 

 nearly simple, except the terminal panicle, sometimes divaricately branched 

 below the middle. Leaves lanceolate or oblong, obtuse or rarely almost acute, 

 coarsely toothed in their whole length or at the base only, or pinnatifid with 

 ovate oblong or rarely linear lobes. Flower-heads rather large' 'for the genus, 

 shortly pedicellate, in dense cymes or clusters, forming a terminal corymbose 

 panicle. Involucral bracts narrow, subulate-acuminate, the inner ones above 



3 lines long. Florets and pappus not exceeding the involucre. Ray-florets 

 exceedingly numerous, all filiform, but not so short as in C viscidula ; disk- 

 florets also numerous, but varying in different heads. — C. lineariloba, DO. Prod. 

 V. 385. 



Hab.: Northumberland Islands, Lizard Island, Broadsound, R. Brown ; Port MoUe, M'Gil- 

 livray ; Burnett and Burdekin Rivers, F. v. Mueller ; Rockingham Bay and Bocbhampton, 

 Dallachy ; Brisbane River, Fraser ; Keppel Bay, Thozet ; also from Leichhardt' s coUeotioa. ' 



The species is common in tropical and subtropical Asia and Africa. Most of the Australian 

 specimens, like some from Amoy (Hance), and the majority of the Mauritius ones I have seen, 

 belong to a variety with the leaves more decidedly pinnatifid than they are usually in the 

 Egyptian and Indian specimens ; but in some of the Australian specimens the leaves are toothed 

 only as in the Egyptian and Indian ones, and one gathered on the Nile by Speke and Grant has 

 them precisely like the common Australian form. — Benth. 



19. -BACCHARIS, Linn. 

 (From one of the species having been dedicated by the Greeks to Bacchus.) 

 Heads many-flowered, dioecious ; florets all tubular and similar. Involucre 

 somewhat hemispherical or oblong, the bracts imbricate in several rows. Recep- 

 tacle naked or rarely chaffy. Corolla in the sterile florets somewhat dilated and 

 5 clefts at the summit; in the fertile filiform, somewhat truncate. Anthers 

 exserted in the sterile florets, entirely absent in the fertile. Style in the fertile 

 florets exserted with, glabrous branches, in the sterile florets tipped with an 

 ovate hairy appendage often more or less abortive. Achenes ribbed or grooved. 

 Pappus capillary ; of the sterile plant in a single series, often tortuous or some- 

 what plumose-penicillate, about the length of the involucre ; of the fertile plant 

 in one or several series, not thickened or penicillate at the apex, usually much 

 longer than the involucre. — Shrubs or undershrubs. Leaves mostly alternate, 

 entire or toothed, often decurrent on the branches. Florets mostly white, rarely 

 yellow or purple. 



All belong to America.
