| Abstract: | Differences in colours of male strobili, originally encountered in races ofPinus mugo, are found among other pine species too: Species of subsect.Cembrae flower bright red, whereas in subsect.Cembroides yellowgreen is dominant. Recently, blue and grey-blue male flowers have been discovered inP. engelmannii from Mexico,P. palustris, P. elliotti andP. densa from Florida. These flower colour differences apparently reflect some species relationships. |
