Supplementary remarks:
It is with hesitation that I treat P. linare as a synonym of P divaticatum and P. crassicaule. Laing & Gourlay, the two authors of P. linare, cultivated and studied the small-leaved New Zealand species of Pittosporum for many years before publishing their results, but in the material cited by them there appear to be two distinct entities, the Koromiko plants (Laing & Gourlay s.n.) which have flowers with sepals 2.0 - 2.5 mm. long, capitate stigmas, styles 1.0 - 1.2 mm long, glabrous overies 2.0 - 2.2 mm. long and stamens about 2 mm. long; and the Pelorous Valley plants (MacMahon s.n.) which have flowers with sepals 1.0 - 1.5 mm. long, truncate stigmas, styles about 1.8 mm. long, tomentulose ovaries 1.5 mm long, and stamens nearly 4 mm long. The linear entire leaves of the Koromiko plant give it a very different appearance from most specimens of P. divaricatum, but the flowers are within the range of variation of P. divaricatum, and similar plants with linear entire leaves bearing the distinctive cordate glabrate fruits of P. divaricatum, occur on the Volcanic Plateau (Attwood s.n.), and in cultivation (Cooper 36299). The tomentulose ovary of the Pelorus Valley plants is a feature of P. crassicaule. P. rigidum and P. obcordatum, but the other characters of the flower, fruits, and foliage are similar to those of P. crassicaule with some misgivings I have included the collection in that species.
