486 ANGIOSPERMAE MONOCOTYLEDONES 



2891. L. spadicea DC. Schulz (' Beitrage/ II, p, 171) and Buchenau state 

 that plants of this species growing in the open air pass through a rather long female 

 stage which, however, ends when the perianth opens, so that after a short neutral 

 interval a male stage follows. In plants cultivated by Buchenau, on the contrary, 

 the hermaphrodite stage followed the female one without any interval. The stigma 

 is greenish-white in colour, with rather short, but not velvety papillae. 



927. Distichia Nees et Meyen. 



2892. D. muscoides Nees et Meyen ; 2893. D. filamentosa Buchen. ; and 

 2894. D. tolimensis Benth. et Hook. These Andean species, which grow near 

 the snow-line, are dioecious. The female flowers are very inconspicuous. The male 

 flowers of the first two species are unknown, those of the last possess a perianth of 

 dark-brown colour, and open into the form of a funnel. 



2895. D. Philippi. This species, native to the desert of Atacama, is dioecious ; 

 the female flowers possess short stalks and the male longer ones ; both forms appear 

 to open into the form of a funnel. 



928. Patosia Buchen. 



The dioecious plants of species belonging to this genus are indigenous to the 

 Cordilleras of Chili. The female flowers are completely concealed in the axils of the 

 foliage-leaves, the stigmas projecting at the end of a very long style. The male 

 flowers possess slender stalks. 



929. Prionium E. Mey. 



2896. P. Palmita E. Mey. This Cape shrub bears hermaphrodite flowers, 

 which open into the form of a shallow bowl. 



930. Rostkovia Desv. 



2897. R' sphaerocarpa Desv. (= R. magellanica Hook./.). This species 

 is indigenous to Tierra del Fuego, and bears large hermaphrodite flowers which 

 open apparently in the form of a star. 



2898. R. grandiflora Hook, f. (= Marsippospermum grandiflorum Hook\i 

 and 2899. R. gracilis Hook. f. (= M. gracile Buchen.). The very large flowers i 

 of these antarctic species open into the form of a funnel, and are apparently 

 protogynous. 



CXVIII. ORDER PALMAE BARTL. 

 931. Sabal Adans. 



2900. S. Adansoni Guerns. Delpino ('Altri appar. dicog. recent. oss.,'j 

 p. 61) describes this species as entomophilous. He saw the nectar-bearing, protc 

 gynous flowers, with a milk-white perianth, visited and pollinated by Hymenopter 

 (Halictus sp., and Polistes gallica Z.). 



932. Chamaedorea WiUd. 

 Species of this genus (Delpino, op. cit.) are also entomophilous.
