Amanita drummondii and A. quenda (Basidiomycota), two new species from Western Australia, and an expanded description of A. walpolei

DAVISON, E.M., GIUSTINIANO, D., MCGURK, L.E., SYME, K. AND ROBINSON, R.M., Nuytsia 25 : 1–13 (2015)

Three species of Amanita Pers. are documented from Western Australia. Amanita drummondii E.M.Davison is described from the south-west region; it appears to be widespread but infrequent. Amanita quenda E.M.Davison is described from the Perth Metropolitan area. Amanita walpolei O.K.Mill. is redescribed to include additional collections, drawing attention to the presence of clamp connections in all tissues. A BLASTn search has shown that there are no exact matches of the nuclear ribosomal internal transcribed spacer (ITS) region of each species with those in GenBank.

Reinstatement of Ericomyrtus (Myrtaceae: Chamelaucieae), with three new combinations

RYE, B.L., Nuytsia 25 : 131–143 (2015)

The south-western Australian genus Ericomyrtus Turcz. is reinstated as a small genus comprising the type species E. drummondii Turcz., and three species transferred into the genus as E. parvifolia (Turcz.)

Revised descriptions are provided for the reinstated L. laxiflorum (Benth.) F.Muell. and newly elevated subspecies of L. glutinosum (Lindl.) F.Muell. (L. glutinosum subsp. glutinosum and L. glutinosum subsp. latifolium (Benth.) K.A.Sheph. & C.F.Wilkins).

Stylidium miscellany II: typification of some Sonder names and the description of a new subspecies of S. uniflorum

WEGE, J.A., Nuytsia 25 : 197–208 (2015)

A full synonymy is presented for S. affine Sond. to include S. affine var. minus E.Pritz., a name previously treated as a synonym of S. caricifolium Lindl. Lectotypes are selected for four species described by Otto Sonder, namely S. lineatum Sond., S. pubigerum Sond., S. rupestre Sond. and S. uniflorum Sond. Stylidium rupestre f. abbreviatum Mildbr., S. rupestre f. congestum Mildbr., S. rupestre f. uniflorum Mildbr. and S. glaucum var. brownei DC. are formally placed into synonymy under S. rupestre, with lectotypes designated for S. rupestre f. abbreviatum and S. glaucum var. brownei. Revised descriptions are provided for S. rupestre and S. uniflorum, and S. uniflorum subsp. extensum Wege is newly described. Putative hybrids between both subspecies of S. uniflorum and S. leptophyllum DC. are recorded.

Recognition of Hysterobaeckea as a genus of Myrtaceae tribe Chamelaucieae

RYE, B.L., Nuytsia 25 : 209–218 (2015)

Baeckea behrii Schltdl. is selected as the lectotype for B. subg. Hysterobaeckea Nied., which is raised to the generic level as Hysterobaeckea (Nied.) Rye. New combinations are made for the three named species that belong to the genus as now defined, and a lectotype is selected for one of those species, B. ochropetala F.Muell. The three new combinations are H. behrii (Schltdl.) Rye, H. ochropetala (F.Muell.) Rye and H. tuberculata (Trudgen) Rye. The distinguishing characters of the genus are outlined and a generic key given for the group to which it belongs.

RYE, B.L., Nuytsia 25 : 219–250 (2015)

In this revision of Babingtonia Lindl., 11 species are recognised, all endemic to the south-west of Western Australia. Previously, the type species B. camphorosmae (Endl.) Lindl. was the only Western Australian species housed as a Babingtonia. The new combination B. grandiflora (Benth.) Rye is made, and nine new taxa are named: B. cherticola Rye & Trudgen, B. delicata Rye & Trudgen, B. erecta Rye & Trudgen, B. fascifolia Rye, B. maleyae Rye & Trudgen, B. minutifolia Rye & Trudgen, B. pelloeae Rye & Trudgen, B. triandra Rye & Hislop and B. urbana Rye. A key is given and some of the taxa are illustrated. Most have conservation priority.

A revision of the Hibbertia hypericoides species group (Dilleniaceae)

THIELE, K.R. AND COCKERTON, G., Nuytsia 25 : 285–300 (2015)

The Hibbertia hypericoides (DC.) Benth. species group comprises four species endemic in Western Australia. Hibbertia hypericoides is the most widespread species of Hibbertia Andrews in Western Australia, and exhibits significant and complex variation. The new subspecies H. hypericoides subsp. septentrionalis K.R.Thiele & Cockerton is described to accommodate a long-recognised form that occurs in the northern part of its range. The new species H. cockertoniana K.R.Thiele, previously included in H. hypericoides, is described. Descriptions are also provided for H. hypericoides subsp. hypericoides, H. silvestris Diels and H. furfuracea (R.Br. ex DC.) Benth., the other taxa in the group.

A distinctive and remarkable new species in Hibbertia Andrew subgen. Pachynema (R.Br. ex DC.) J.W.Horn is described and illustrated. Hibbertia paranthera K.R.Thiele sp. nov. differs from all other species in subgen. Pachynema (and in the whole of Hibbertia) in having an androecium reduced to two large stamens, and a corolla of three petals. The new species is currently known from two populations c. 30 km apart in sandstone habitats in a remote area in Prince Regent National Park, between the Prince Regent River and Prince Frederick Harbour.

A taxonomic revision of the Stylidium brunonianum alliance (sect. Saxifragoidea: Stylidiaceae)

WEGE, J.A., Nuytsia 25 : 313–342 (2015)

A morphological assessment of Stylidium brunonianum Benth. and its allies recognises eight taxa, all of which are endemic to the south-west of Western Australia. Following examination of type material and field work, a narrower circumscription of S. brunonianum is presented, S. tenue Sond. is reinstated and the following five taxa are newly described: S. araeophyllum Wege, S. neurophyllum Wege, S. purpureum Wege, S. spiciforme Wege and S. tenue subsp. majusculum Wege. A revised description is provided for S. lowrieanum Carlquist, a conservation-listed species from the Leeuwen-Naturaliste Ridge. Lectotypes are selected for S. brunonianum, S. tenue and S. brunonianum var. minor Benth., with the varietal name newly placed into synonymy under S. tenue. A lectotype is also designated for the name S. striatum Lindl. var. glaucum Benth. (based on collections of S. lowrieanum, S. neurophyllum, S. bellum Wege and S. rosulatum Wege) to fix its application as a synonym of S. rosulatum. A dichotomous key to the S. brunonianum alliance is provided along with photographs of key features and distribution maps.
