Seeking for help：an obscure word

[vigor]

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.

[Maggi Young]

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

[vigor]

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

[Jupiter]

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

[Danshi]

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