West-Australian M. serratum, but in fruit very different, and comes thus far 

 near M. floribundum ; indeed it belongs to the series , which on carpologic 

 characteristics was generically separated byAlphonse deCandolle as Disoon, 

 of which subgenus only M. platycarpum and M. floribundum are known from 

 Eastern Australia, both very difterent in foliage from the new congener now 

 recorded. Irrespective of the difference of the very narrow leaves, M. flori- 

 bundum has rather acute lobes of the corolla , the tube of which surpasses 

 considerably the length of the calyx, and the fruit is nearly twice as long 

 as broad. M. platycarpum becomes a small tree , and is restricted tho the 

 desert regions of South-Eastern Australia; its leaves are smaller and more 

 rigid than those of M. Batese, their serratures are more distant and they 

 occur only towards the upper end of the leaves, the calyx has the shortness 

 of that of M. floribundum, the corolla is more bearded, the fruit flatter and 

 longer, thus stretching mucli beyond the calyx, besides being attenuated into 

 an acute apex and marked upwards along the middle of each side by a 

 prominent line. The true M. serratum difiers from Miss Bate's plant in 

 offen shorter leaves, rather longer pedicels, longer and difl'erently shaped 

 Segments of the calyx, more bearded corollas with longer lobes, an offen 

 downy style and especially in 3- or 4-celled and all round turgid fruits with 

 a thicker endocarp. In reality M. serratum is very closely allied to M. oppo- 

 sitifolium, but not the arboi'escent M. insulare, with which Bentham combined 

 it, and which as well as M. tenuifolium occurs also near Mount Dromedary, 

 but in subsaline litoral regions. The botanical collections of the lady who 

 discovered this Myoporum contain furthermore several plants especially worthy 

 of record as not having been found iormerly so far south (Lat. 36" 20'); these, 

 with others obtained additionally from Mr. Reader, — since notes on his 

 plants were published in the last year's volume of the Linnean Society of 

 New South Wales, jjp. 287-318 — are comprised in the following list: Clematis 

 glycinoides Candolle. Hibbertia volubilis Andrews. Doryphora Sassafras 

 Endlicher. *Cryptocarya glaucescens Brown. Vitis Baudiniana F. v. M. 

 *Synoum glandulosum A. de Jussieu. Phyllanthus Gastroemii J. Mueller. 

 Muehlenbeckia gracillima Meisner. Alphitonia excelsa Reissek. Acacia 

 falcata Willdenow. Eucalyptus robusta Smith. *Apium leptophyllum F. v. M. 

 Xanthosia Atkinsonise F. v. M. Aster dentatus Andrews. Crepis japonica 

 Bentham. Solanum violaceum Brown. *Myoporum tenuifolium G. Forster. 

 *Myoporum Batese F. v. M. Ipomoea palmata, Forskael. Lyonsia reticulata 

 F. V. M. Cymbidium suave Brown. Sarcochilus falcatus Brown. *Sarcochilus 

 olivaceus Lindley. *Sarcochilus tridentatus G. Reichenbach. Rhynchospora 

 diandra Sprengel. Lindsaya microphylla Swartz. Lysimachia japonica Thunb. 

 Dendrobium gemulum R. Br. Bulbophyllum exiguum Müell. Viscum arti- 

 culatum Burman. Of these Eucaly|3tus robusta has been noted still further 

 south (at Merimbula) and Rhynchospora diandra as extending to the Genoa. 

 Further we have now become aware. that the following plants, mostly of 

 Tasmanian type, advance into New South Wales, at least to the vicinity of 

 Mount Dromedary: Correa Lawrenciana Hooker. Muehlenbeckia appressa 

 Meisner. *Australina pusilla Gaudichaud. Epacris impressa Labillardiere. 

 Mentha gracilis Brown. Casuarina quadrivalvis Labillardiere. Hierochloa 

 rariflora J. Hooker.*) What renders these data particularly interesting is the 

 fact of their demonstrating how very far southward some tropical forms of 

 plants extend through the mild litoral tracts of East-Australia, as shown 

 for instance by the occurrence of several epiphytal Orchids; whereas even in 

 equal isothermal zones none are represented by equivalent exponents in the 

 whole flora of Europe anywhere.**)
