remark that the large-leaved seedling plant described above 

 resembles very much in leaf-form the figure on pi. 38d, in 

 Kirk's ■' Forest Flora," of Pseudopanax crassifolia, var. wii- 

 foliata, while in many instances the mature leaves of our 

 plant are not unlike those of P. crassifolia, var. trifoUata 

 (pi. 38c). The truncate form of leaf so common in the mature 

 form of P. chathamica seems strongly hereditary, as evidenced 

 by so many leaves being only partly developed, even amongst 

 the early seedling leaves. 



No. 851. Carmichaelia enysii, T. Kirk. Plate IX., figs. 16, 



17, 18. 



Seed collected by Mr. W. G. Eutherfurd in the neighbour- 

 hood of Kurow, Otago. Sown 1st September, 1899 ; germi- 

 nated 6th September, 1899 — five days. 



Description of Seedling. 



Early development : The cotyledons remain enclosed in 

 the seed-coat while the hypocotyl and radicle develope to the 

 extent shown in fig. 16, where the cotyledons have just 

 emerged from their covering. The hypocotyl is white, and 

 already exceedingly thick and succulent. The thick cotyle- 

 dons as they open out become green and rapidly increase in 

 size, while from between them a shoot emerges, which is at 

 first quite terete, and having its growing-point protected by 

 succulent ciliated stipules ; as development proceeds it be- 

 comes much flattened above, and is furnished at the nodes 

 with small stipules, from the axils of which rudimentary 

 buds emerge. By the end of fifty-four days the state de- 

 scribed above had been reached. 



Hypocotyl 10 mm. loiag, mostly tibove ground, very pale- 

 green, thick, fleshy, glabrous. 



Cotyledons obovate- or oblong-spathulate, sometimes fal- 

 cate, extremely succulent, thick and juicy, glabrous, shortly 

 petiolate with petioles channelled on upper sui'face and con- 

 nate at base. 



Cladode 4-5 cm. long (in oldest specimen), 2-75 mm. broad 

 in widest part, terete near base, green, much grooved, sparsely 

 hairy with adpressed rather bristly white hairs, erect, slightly 

 fiexuous. 



Stipules small, adpressed to and enclosing adjacent margin 

 of cladode, broadly triangular, succulent especially when 

 young, ciliated at margin and hairy on under-surface ; hairs 

 as on cladode. 



Carmichaelia enysii is a very dwarf shrub found in the 

 very driest portions of the lower mountain region of the South 

 Island, and, according to Kirk, on the south-east side of 

 Euapehu, North Island. It grows on stony flats, old river- 

 beds, river-terraces, and the like, forming large dense patches
