308 lewton: the Australian fugosias 



proposed the genus Allogyne'^ for Fugosia hakeaefolia, and al- 

 though mistaken in stating that the involucre is wanting, he was 

 correct in separating this species form Hibiscus, where it had 

 been placed when first described by Giordano^^ in 1834. With 

 F. hakeaefolia are to be associated three nearly related species, 

 Hibiscus multifidus Paxton, H. lilacinus Lindley, and Fugosia 

 cuneiformis Benth., the four constituting the genus AUogyne. 



Aliogyne Alefeld. 



Succulent, glabrous seaside shrubs, sometimes gland-dotted. Leaves 

 cuneate or spatulate and entire or lobed, or deeply divided into terete 

 or flattened, sometimes deeply toothed segments. Flowers borne on 

 thickened peduncles, showy, not evanescent, persisting several days. 

 Involucre a shallow 5- to 7-toothed cup, situated 3 to 5 mm. below 

 the calyx, the ovary thus appearing stipitate. Calyx deeply 5-parted, 

 its base (within the involucre) covered with nectar-secreting hairs. 

 Sepals lanceolate, not completely valvate, only partially enclosing 

 the bud. Corolla white, blue, or lilac, usually with a crimson-purple 

 eye in the throat. Ovary 4- or 5-celled; style 1; stigma 1, slightly 4- 

 or 5-lobed. Capsule 4- or 5-celled, usually covered with appressed 

 silky hairs. Seeds bristly with spreading hairs, not downy. 



The genus Aliogyne may be distinguished from Hibiscus by the un- 

 divided style, the aestivation of the sepals, and the presence of black 

 glands; from Notoxylinon by its succulent character, epidermal cov- 

 ering, and extra-floral nectary; from Cienfuegosia by the distribution 

 of the black glands and the extra-floral nectary; from Gossypium by 

 the absence of black dots from the cotyledons ; and from all the above- 

 named genera by the form of the involucre and the persistent character 

 of the flowers. 



The species of Aliogyne may be recognized by the following key: 



Leaves undivided or occasionally lobed, cuneate 



or spatulate; flowers white 1. A. cuneiformis. 



Leaves bipinnate or deeply parted; flowers blue, 

 lilac, or purple. . 



Leaf segments flat; corolla without crimson- 

 purple eye 2. A. UJacina. 



Leaf segments terete; corolla with crimson- 

 purple eye. 



^^ Oesterr. Bot. Zeitschr. 13: 12. 1863. (Here the name of the genus is 

 spelled Alyogyne and on the opposite page Alyogone, both evidently printed 

 in error for Aliogyne, from aXXos, different, and ywr], stigma.)
