• 



slightly pubescent especially when young, pedicel at most equalling the 

 calyx, pale-coloured. Flowers minute, about 3-5-4 mm. long; calyx cam- 

 panulate, glabrous, 2 mm. long (to tip of tooth), pale yellowish-cream 

 dotted pale purple, teeth narrow, acute, rather long, dark purple ; standard 

 about 3 mm. long by 4 mm. broad, upper surface cream-coloured on lower 

 half, above dark purple marked with almost black lines passing obliquely 

 from median line of leaf, paler beneath, slightly exceeding the keel ; wings 

 cream-coloured more or less tinged yellow, equalling keel, oblong, rather 

 narrow ; keel near apex dark purple, beneath yellowish to cream-coloured. 



28. Carmichaelia Monroi Hook. f. 



Two years ago Mr. B. C. Aston, F.I.C., while investigating the flora 

 of the Clarence River basin, collected a supposedly undescribed species of 

 Carmichaelia a description of which is given below. The examination of 

 Aston's material led me to a comparison with that in my herbarium of 

 C. Monroi Hook, f., with the result that the Clarence Valley plant may be 

 the true C. Monroi, and that the forms included by Kirk, Cheeseman, and 

 others under that name may be either one or two undescribed species or 

 very distinct varieties of C. Monroi. This conclusion is quite unexpected, for 

 few species in the flora seemed to be better understood than is C. Monroi. 



Description of Aston s Clarence Valley Species of Carmichaelia. 



A stout rupestral much-branched shrub with spreading, more or less 

 drooping, leafless branches, up to 60 cm. long. Branchlets rigid, green, 

 flat, grooved, + 12 cm. long and up to 9 mm. wide, hoary pubescent when 

 young with short appressed hairs which also extend at times to the older 

 branchlets. Racemes + 5 cm. long, frequently 7-flowered ; rhachis and 

 pedicels densely pubescent with appressed white hairs ; pedicels slender, 

 about 6 mm. long. Flowers about 10 mm. long. Calyx campanulate, densely 

 hairy, 5 mm. long ; teeth 3 mm. long, narrow-triangular, acute, standard 

 rather longer than the keel, 10 mm. long, 7 mm. broad, ? cream with large 

 purple blotch in centre whence 1 purple lines radiate to margin and apex ; 

 wings 6 mm. long, 2-5 mm. broad, marked with ? purple lines ; keel 9 mm. 

 long, blotched with 1 purple near apex and marked with ? purple lines. 

 Pods 12-17 mm. long, black when ripe, turgid ; valves wrinkled ; beak 

 oblique (straight in one specimen), usually short but up to nearly 3 mm. 

 long ; seeds pale brown mottled with black, rather large, 3 mm. long. 



South Island : North-eastern Botanical District — On shaded faces of 

 limestone cliffs in various gorges on the south-eastern side of the Inland 

 Kaikoura Mountains. B. C. Aston! 



Had this limestone-cliff plant been the only species of Carmichaelia 

 in its immediate locality, its altogether different habit, together with its 

 much longer and wider branches and hoary branchlets, its 7-flowered 

 racemes, and its larger flowers, would separate it from any forms of C. 

 Monroi as at present understood. But on stony debris, in close proximity 

 to the rock-plant, but in the open, Mr. Aston collected specimens of a Car- 

 michaelia with short close branchlets like those of C. Monroi of the Manual 

 except that they are pilose as in the rupestral plant. Unfortunately their 

 pods, &c, are too immature in the specimens at my disposal for further 

 comment. 



The type of Carmichaelia Monroi Hook. f. was collected by Monro 

 " from half-way up to the summit of Macrae's Run " (Awatere River basin) :
