NOTKS FROM THE BOTANIC GARDENS, SYDNEY, 



Verticordia DARWINIOIDES. 



Bracteoles large, enclosing the 

 flower buds and long persistent, 

 thin and scarious. 



Calyx-tube cylindrical, 5- 

 ribbed, smooth, about 3 lines 

 long, the lobes deeply divided 

 into 5 to 8 narrow filamentous 

 segments, about twice as long 

 AS the petals. 



Petals ovate, about 1 line long, 

 entire. 



Stamens mostly eaten off by 

 insects, so that they could not be 

 distinguished from staminodia. 



Anthers nearly globular as 

 far as seen, but destroyed or 

 damaged by insects. 



Sti/le slender, much exserted, 

 bearded towards the end. 



Ovides 2 only in the ovaria 

 examined. 



Rylstonea cernua. 



Bracteoles forming a hood over 

 the corolla and folding over each 

 other on the liower bud, and not 

 falling oif till the petals expand, 

 scarious on the edges. 



Calyx-tuhe cylindrical, pro- 

 minently 5-ribbed, 5 to 6 lines 

 long, lobes simply divided into 

 about 5 to 10 divisions, about 

 twice as long as the petals, the 

 outer lobes with accessory lobes. 



Petals entire, imbricate, semi- 

 circular, contracted at the base. 



Stamens lU, in a ring at the 

 base of the petals; staminodia 

 alternating with the stamens. 



Anthers globular, with two 

 parallel cells, opening by minute 

 pores, ttc. 



Style well exserted, thick at 

 the base and tapering upwards, 

 bearded towards the end. 



Ovules about 8, attached to a 

 peltate placenta, &c. 



It will be clearly seen from the above comparative extracts 

 that the difference between the two plants lies chiefly in the size 

 of unessential organs (except the difference in the number of 

 ovules, which is probably due to the defective insect-eaten 

 material we had to work upon), (juite in keeping with the theory 

 that our specimens were abnormal ; all other differences are 

 trifling or explainable. The flowers in the Dubbo specimens are 

 scarcely nodding, owing to the short peduncles, but very con- 

 spicuously so in Rylxtonea with the long slender peduncles.
