 Urban.] 



Cultivated and waste grounds. 

 Naturalized. Native of tropical and 

 warm-temperate regions. Flowers in 

 spring. Widely naturalized in the 

 southern United States. 



Angelica Archangelica L., ANGELICA, European, has been grown in gar- 

 dens; it is a biennial tall herb, with finely divided leaves, the lower with 

 long, round stalks, which are candied; its roots are aromatic, its small white 

 flowers in compound umbels. 



Cerefolium Cerefolium (L.) Britton, GARDEN CHERVIL, BEAKED PARSLEY, 

 European, grown as a garden herb, has linear beaked smooth fruits, white 

 flowers and ternately decompound leaves. [Scandix Cerefolium L. ; Chaero- 

 phyllum sativum Lam.] 



Anthriscus Anthriscus (L.) Karst., BUR-CHERVIL, European, is recorded 

 by Lefroy as a common weed in his time, but it has not been found by recent 

 collectors, and is not mentioned by Eeade in his book published in 1883. It 

 is a white-flowered plant with decompound leaves and ovoid, short-beaked, 

 muricate fruits. [A. vulgaris Pers.] 



Lefroy records the introduction of Ferula glauca as an ornamental species 

 in 1874. 



Coriandrum sativum L., CORIANDER, European, is recorded by Lefroy as 

 quite naturalized prior to 1877 in some fields at Point Shares but it is not 

 known to grow there at the present time, and it is not mentioned in Eeade 's 

 "Plants of Bermuda" published in 1883, although Hemsley cites it from 

 Lefroy, and H. B Small records it as not uncommon. 



Daucus Carota L., CARROT, European, is grown as a field and garden crop, 

 but it is not naturalized as a field weed as it is on the continent. 



Pastinaca sativa L., PARSNIP, European, is also grown as a field and 

 garden crop, but not naturalized as a weed as in the United States. The 

 flowers are yellow, the fruit flat and winged, the large pinnate leaves with 

 ovate sessile toothed or incised segments. 



Didiscus coeruleus (Graham) Hook., DIDISCUS, Australian, a roughish- 

 hairy annual about 2 high, with ternately divided leaves and long-stalked 

 umbels of bright blue flowers, the involucre of many, narrowly linear, pilose 

 bracts, the flat fruits notched at base and apex, was grown at Rose Cottage in 

 1914. [Tracliymene coerulea Graham.]
