Studies on the Stellaria longipes complex (Caryophyllaceae): relationships among the species based on seed protein profiles

CHINNAPPA, C. C, GIFFORD, D. J. & RAMAMORRTHY, J., 1992. Studies on the Stellaria longipes complex (Caryophyllaceae): relationships among the species based on seed protein profiles. The protein profiles of nine genera of the family Caryophyllaceae show distinct patterns. Within the genus Stellaria , six species were studied. The four North American species show more or less similar profiles, while the two European species have quite different patterns. There are some indications to suggest that the polyploid species, 5. longipes , is closely related to diploid S. longifolia and S. porsildii. The seed protein profiles of these species support the view that 5. longipes might have originated from hybridization between the two diploid species.     

Ruellia section Chiropterophila (Acanthaceae): a novelty from Mexico

RAMAMOORTHY, T. P., 1991. Ruellia section Chiropterophila (Acanthaceae): a novelty from Mexico. A brief review of the structure of the genus Ruellia is provided. A new section, ft. section Chiropterophila is described. Ideas regarding evolution in the section are offered. It is suggested that some of the taxa in the section may be neoendemics.
