•cuneate at the base ; midrib raised on under-surface of leaf, 

 projecting beyond base of leaflet, slightly bent downwards, 

 and articulating with petiole, thus raising the horizontal 

 leaflets slightly above the petiole ; terminal leaflet usually 

 longest. 



Other leaflets rather smaller than the earlier ones. 



Stipules subulate, membranous, rarely rounded at apex. 



This species is described in the Students' Flora, recently 

 published (p. 11 4).''' It is one of the leafy species, and seems 

 to be very similar, judging from the description (p. 114), to 

 C. grandi flora, the seedling form of which has not yet been 

 described. Like nearly all the seedling Carmichaelias that 

 I am acquainted with, it has entire, almost rotund, leaves at 

 first. The mature leaves, according to Kirk, are deciduous. 



Notospartium torulosum, T. Kirk. 



Seedlings raised by Mr. S. D. Barker from seed collected 

 in his garden from plant brought originally from Mount Peel. 

 Germinated in about fourteen days (Barker). 



Description of Seedling. 

 Early development : The hypocotyl reaches a length of 

 8 mm. before the pale-coloured cotyledons are released from 

 the seed-coat, which still encloses their upper and apical 

 halves. At this stage the cotyledons lie with their upper 

 surfaces pressed close together. As development proceeds 

 the hypocotyl, at first pale-coloured, tender, and semipros- 

 trate, becomes green, woody, and erect, while the cotyledons 

 gradually open out, increase in size, becoming finally 9 mm. 

 long X 4 mm. broad ; are fleshy, obovate-oblong, slightly 

 falcate, glabrous, petiolate with very short petioles, which are 

 connate at the base. While the cotyledons are slowly de- 

 velopmg, the growing point of the stem emerges from between 

 them, and rapidly developes the 1st internode, while at the 

 same time the 1st leaf is being developed, which quickly 

 becomes furnished with a petiole longer than the internode, 

 the lamina at the same time growing very quickly, becoming 

 1 cm. in length, rotund in shape, with emarginate apex and 

 surface semipatent. By this time the 2nd internode is 

 lengthening, with a leaf being developed at its apex, having 

 a short thick petiole, and the sides of the lamina pressed 

 closely together and vertical. The 3rd internode is now 

 very short, and is enclosed and protected by two triangular 

 stipules, furnished at their apices with one or more hairs. 

 At this early stage the leaf has a red margin, not to be seen so 

 far in the more mature leaves. x\s the 2ud leaf developes, the
