Frullania hattorii von Konrat & Braggins
von Konrat, M. and Braggins, J. E. (2003). New Zealand Journal of Botany. 41:56.

This species was named in honour of the late Dr Sinske Hattori, who described many Frullania species for the Australasian region.

Species Description: (See also: Detailed Description)

Plants small to medium (main shoots to 600 m wide), olive-green, copper-brown, or black, in appressed mats. Branching of Frullania-type with progressively smaller leaves. First branch underleaf (BUL1) with three distinct segments, the ventral lamina divided for _ its length into two subequally sized lobes + 1 dorsal saccate lobe. First branch leaf (BL1) usually reduced in size, ventral segment elobulate, explanate, rarely sulcate, with leaves characteristic of the main stem starting at BL3, occasionally BL1 with two distinct segments, a strap-shaped dorsal segment +1 saccate ventral segment (+ a stylus). Stem leaves of main shoot flat when dry and wet, dorsal surface conspicuously mammillose, each cell bearing one conical protuberance to c. 8 µm high; margins entire but often sinuate. Lobules µ remote from the stem, cylindrically pitcher-shaped, somewhat dorsiventrally compressed near mouth in comparison to the gibbous upper half with an obtuse apex. Stylus small, uniseriate to triangular. Underleaves: bilobed, lateral margins of each lobe with (1) 2-3 blunt-acute teeth.
Median cells of leaf lobe with hyaline, subequally thickened walls by way of indistinct trigones at the cell angles and the absence of any conspicuous intermediate thickenings along the intervening walls.
Monoicous, usually cladautoicous with androecial branches a short distance below the inflorescence, occasionally gonioautoicous. Perianth freely emergent, oblong-ovate, 1250 µm long µ 600 µm wide, exterior smoothly trigonous.
Elaters of 32-42 per capsule. Spores globose, to 50 µm diam., with 6-8 rosettes (concavities), ± uniformly pantoporate in distribution; rosettes bearing an outer ring of ± 6-10 tuberculate stelae grading into an inner ring of 6-8 conspicuous, echinate stelae, the individual stelae usually papillate with 1-3 minute secondary deposits, and occasionally divided into 1-2 simple short branches (especially towards the apex).

Recognition in field/Identification:

In the field, both F. hattorii and F. aterrima can typically be separated from F. rostrata by comparing the contrast in colour between the leaf-lobule and leaf-lobe. The lobules of F. hattorii are almost always darker in colour than the other organs (in part due to heavily pigmented cell walls) whereas the lobules of F. rostrata are similar in colour to the other organs.

Index

Relationships:
This species is placed in subgenus Microfrullania (R. M. Schust.) R. M. Schust. with which it shares several common features, including, the obliquely spreading lobules and the subequally thickened cell walls of the leaf lobe. Frullania aterrima is a morphologically similar Australasian species, and F . rostrata is a common species throughout Tasmania, Australia, and New Zealand, and some phenotypes of F. rostrata may be confused with this taxon. However, no other Frullania species in Australasia has the distinct form of cell ornamentation on the leaf lobe.

Type Data: HOLOTYPE: Australia. Tasmania, Hartz Mountains National Park, Lake Osborne Track, mixed forest dominated by stringybark (Eucalyptus obliqua) and a rainforest community including Nothofagus cunninghamii, growing on bark of Nothofagus cunninghamii in shade, c. 900 m., c. 43°14'S 146°44'E, J. E. Braggins 98012, 14 Feb 1998, Holotype: TAS; Isotypes: AK, F.


Index

Geographic distribution:



At present, F. hattorii is only known from three localities in Tasmania: Hartz Mountains National Park, Mt Field National Park, and south-west of Nietta. Further collections are required to establish the full extent of its distribution, and searching in similar habitats on mainland Australia may also be useful (von Konrat & Braggins 2003).


Index

Habitat:

Based on the limited collections thus far it appears that this species occurs in moderate to high light environments at mid to high altitude.
