4°2 ANGIOSPERMAE—MONOCOTYLEDONES 



2862. J. lomatophyllus Spreng. — Intermittence is extremely marked in this 

 species. Anthesis lasts three days. A short female stage follows the hermaphrodite 

 one of the second day. The stigmas are purple-red in colour, with widely projecting 

 transparent papillae. 



2863. J, maritimus Lam. — No intermittence can be observed in this species. 

 Anthesis last about 36 hours. The female stage lasts the whole day. The stigmas 

 are of a beautiful purple-red colour, with velvety papillae. 



Visitors. — Scott-Elliot (Dumfriesshire) observed a wasp (' Flora of Dumfries- 

 shire,' p. 175). 



2864. J. obtusiflorus Ehrh. — The plants of this species flower with marked 

 intermittence, there being intervals of three to four days when no flowers open. 

 Anthesis lasts one day ; the female stage two to four hours. The stigmas are 

 white in colour with a faint reddish tinge. The papillae are moderately long. 



2865. J. pelocarpus E. Mey. — Buchenau examined herbarium specimens of 

 this North American species; it possesses numerous flowers opened in the shape 

 of a star, so that the plant probably blooms distinctly intermittently. Before the 

 perianth opens the elongated stigmas project from the closed flower. 



2866. J. ptinctorius L. — The anthesis of this species resembles that of 

 J. obtusiflorus Ehrh. Distinct intermittence has not been observed. The stigmas 

 are like those of J. obtusiflorus. 



2867. J. pygmaeus Rich. — The flowers of this species open between 6-7 a.m. 

 and close again at midday; the anthers dehisce about 9 a.m. The fully opened 

 flower is tuhp-shaped. When the perianth closes the stamens and stigmas are 

 pressed so closely together that the flowers appear to be cleistogamous, but real 

 cleistogamy occurs. The stigmas are bright purple in colour, with long, projecting 

 papillae. 



2868. J. repens Michx. — This species is indigenous to Cuba and the southern 

 United States of North America. Buchenau examined herbarium specimens. It 

 seems to be cleistogamous. 



2869. J. setaceus Rostk. — This species is indigenous to the south-eastern 

 United States and seems (from herbarium specimens) to be always cleistogamous. 



2870. J. squarrosus L. — This species flowers distinctly intermittently. An- 

 thesis lasts less than 12 hours. Early in the morning the open flower is female, 

 the anthers dehisce after 8 a. m., and the blossom closes again soon after midday. 

 The stigmas are brick-red in colour, with long, transparent papillae. Schulz 

 ('Beitrage,' I, p. 102) states that in the Riesengebirge the flowers are homogamous 

 or very feebly protogynous. The stigma often only matures completely after the 

 opening of the perianth. It is generally receptive until after the dehiscence of 

 the anthers. In dull weather the flowers do not seem to open much, and many 

 then fade pseudo-cleistogamously. 



2871. J. striatus Schousb. — There is no intermittence in this species. The 

 stigmas project from the closed flowers. This female stage lasts one day. The. 

 hermaphrodite one in the opened flower is over in less than 12 hours. On 

 the third day the flower opens again and is once more female, and on the
