Title: Seeking for help：an obscure word
Post by: vigor on May 12, 2016, 02:12:44 PM

An obscure word that describe plants produce definite number of leaf in a grow season or even in a lifetime（eg. Pleione and many other orchis）, rather than common trees that can produce new leaves when the terminal bud was injured.
It is a scientific term and I saw it somewhere but I can‘t remember it.

I was speaking last evening to Prof. Ian Alexander - he told me the term is  "determinate"     8)

Thank you, Jupiter and Maggi ! I was expecting a much more rarely-used word but the word  "determinate" may describe pleione foliage as well.

I was thinking determinate too but it's not quite right. There's monopodial vs. sympodial too.

I'd say Pleiones grow sympodial with unifoliate or bifoliate shoots.
