Theor Appl Genet
. 2013 Nov;
70(4):355-62.
PMID: 24253005
Pontederia cordata L. (Pontederiaceae), a perennial diploid, possesses the rare genetic polymorphism tristyly. A controlled pollination programme was conducted over a three year period, under glasshouse conditions, on 36 clones...

Trends Ecol Evol
. 2011 Jan;
11(2):73-9.
PMID: 21237765
Plants exhibit complex mating patterns because of their immobility, hermaphroditism and reliance on vectors for pollen transfer. Research on plant mating attempts to determine who mates with whom in plant...

. 2011 Jan;
5(5):144-8.
PMID: 21232342
The origin and adaptive significance of heterostylous breeding systems have fascinated evolutionary biologists since Darwin's early work on the subject. Models of the evolution of heterostyly differ in the emphasis...

Theor Popul Biol
. 2001 Apr;
59(2):145-55.
PMID: 11302759
The evolutionary dynamics of neutral alleles under the Wright-Fisher model are well understood. Similarly, the effect of population turnover on neutral genetic diversity in a metapopulation has attracted recent attention...

Evolution
. 2000 Dec;
54(5):1533-45.
PMID: 11108582
Trade-offs between flower size and number seem likely to influence the evolution of floral display and are an important assumption of several theoretical models. We assessed floral trade-offs by imposing...

Heredity (Edinb)
. 2000 Jun;
84 ( Pt 5):514-24.
PMID: 10849076
Populations of the insect-pollinated geophytes Narcissus assoanus and N. dubius (Amaryllidaceae) are commonly dimorphic for stigma height. An extensive survey of populations of the two species in SW France revealed...

Heredity (Edinb)
. 2000 Jun;
84 ( Pt 5):502-13.
PMID: 10849075
An unusual stylar dimorphism occurs in Narcissus, a plant genus of insect-pollinated Mediterranean geophytes. To determine the characteristics of the sexual polymorphism, we investigated floral variation in 46 populations of...

. 2000 May;
87(5):748-51.
PMID: 10811799
There has been disagreement concerning the nature of sexual polymorphisms in Narcissus, a genus of insect-pollinated geophytes native to the Mediterranean. The existence of trimorphic heterostyly in the genus has...
