Identification type:
Determination
Note:
But determined without strong conviction. I do not think this is H. didictyon (based on axillary hair teminal cell shape and dimensions) and I am doubtful that H. discolor Mitt. occurs in New Zealand.
I have attempted to key this specimen using Kruijer’s key in the Australian Flora, which is identical to the key in the draft treatment of Hypopterygiaceae received from him. I find this key singularly difficult to use. I am unable to use and am unimpressed with his character of the number of ranks of stipe and rachis leaves. I am unable to use and am unimpressed with his character of laminal cell types/shapes. I am tentatively convinced that axillary hair terminal cell morphology is of value, but it is a difficult character to use.
In this collection the axillary hairs are short, with the terminal cell c. 1.5: 1. [24 × 33 µm, 21 × 30 µm, 18 × 30 µm, 21 × 36 µm, 21 × 30 µm; x=32 µm long, n=5]. They are thick-walled. A few of them were clearly rough-walled or bore surface deposits but I had difficulty observing this in others. In form they agree with Kruijer’s illustrations (as extracted for Flora).
I have seen the hairs in ventral view of a frond branch with amphigastria and lateral leaves removed one by one in a basipetal to acropetal direction (this is easy & quick to do). I find that two branches of about 5 mm length is appropriate. I have not stained.
