I want to make voucher specimen with Pterygota alata / Pterospermum acerifolium/ Sterculia villosa/foetida/versicolor/hamiltonii etc. >>>>Sterculiaceae (Chronquist) or Malvaceae (APG IV)
Plants are very tall, I can't reach easily, if i only collect leaves with petiole without flower or fruit will it be accepted in the herbarium as voucher specimen? What can I do for those big trees to make voucher specimen out of them? Thanks in Advance
If you have access to a pole pruner (basically a saw or shears on a very long handle) you may be able to obtain your samples. Or, ask if detached and fallen flowers/fruits would be acceptable as part of the collection.
If you end up using a ladder and/or other equipment be sure to go with at least one other person for safety!
