486 ANGIOSPERMAE — MONOCOTYLEDONES 



2891. L. spadicea DC. — Schulz ('Beilrage,' 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.), 

 and 2899. R. gracilis Hook. f. {— M. gracile Buchen.). — The very large flowers 

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

 protogynous. 



CXVni. ORDER PALMAE BARTL. 

 931. Sabal Adans. 



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

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

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

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



932. Chamaedorea Willd. 



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