sparse hirsute, stigmate fusiformi continue glabro anguloso, 

 nucibus ovatis acuminatis crasse compressis facie intima paene 

 glabra extima dense hirsuta marginibus exalatis longe ciliolatis. 



Loc. Watheroo, rabbit-proof fence ; Max Koch (no. 1522). 



Frutex 3-4 ped. alt. Folia omnia 3-4|- unc. long. ; lobi 9-12 lin. 

 long. Strobilus 9-12 lin. long., 5-6 lin. diam., interdum partim 

 abortivis et brevibus. Perianthium 5-6 lin. long. 



Eeadily distinguished from alhed species by the foliage. It 

 seems best placed in section Symphyolepis Endl., its nearest 

 affinity appearing to be P. macrostachya R. Br. 



Persoonia pungens. Suffruticosa, diffusa, ramulis albido- 

 tomentosis, foliis infiorescentiisque glabris, foliis ovatis vel 

 ovato-lanceolatis pungentibus breviter petiolatis rigidis obscure 

 uni-nerviis, pedicellis subterminalibus axillaribus solitariis, peri- 

 anthiis flavis segmentis dorso apiculatis, antheris quam perian- 

 thium brevioribus connectivo ultra loculos non producto, ovario 

 conspicue stipitato glabro uniovulato, stylo modice robusto 

 antheris sequilongo. 



Loc. Kellerberrin ; F. H. Vachel. Prope Kellerberrin ; leg. 

 W. V. F. 



Suffrutex 1-1| ped. alt. Folia plerumque 5-6 lin. long. Pedi- 

 celli vix 1 lin. long. Perianthium circiter 4 lin. long. Fructus 

 ignotus. 



The species belongs to the section Ambly anther ce, its nearest 

 western affinity being P. Leucopogon S. Moore. It differs from 

 that plant, among other characters, in the foliage, the glabrous 

 perianth, and in the uniovulate ovary. Among eastern species it 

 more closely approximates P. oxycoccoides Sieber, from which it 

 is readily distinguished by the flat pungent-pointed leaves and the 

 dorsal points to the perianth-segments. 



THE SHEPHERD'S PURSE AND CULTIVATION. 



By E. Adrian Woodruffe-Peacock, F.L.S. 



The Shepherd's Purse {Capsella Bursa-pastoris) is an areal 

 follower of cultivation in Lincolnshire, as a rule. It requires full 

 sunlight, and half or full shelter from the wind. So far as my 

 observation yet extends it is merely visited by Diptera while 

 resting in the high summer months, and by Thrips (Thysanoptera) 

 when in large flights at such times as every flower, even grass 

 flowers, are visited by them. In both cases there was pollen on the 

 insects or their legs and cross-fertilization might accrue ; though 

 I regret I do not know how to prove it does. It flowers, i.e. sheds 

 active pollen, every month of the year — every day of the year, 

 as a matter of fact, when the thermometer is above 86 degrees 

 Fahrenheit, provided there is bright sunhght during some part of 

 the daylight hours. Poa annua and Groundsel are the only two 

 other species which flower more continually ; they can do with
