18. Note on Corallospartium crassicaule (Hook, f.) Armstrong. 



Mr. A. W. Roberts, of the Ranfurly State Nursery, lately sent me a 

 packet of ripe pods of this species. Both Armstrong and Cheeseman state 

 that the the ripe pod contains a single seed, though the latter notes that 

 the ovules are 2-1 in number. An examination of some two dozen of the 

 pods from the Maniototo district showed that the usual number of ripe 

 seeds in each pod is two. three were present in a few cases, and with about 

 equal frequency the number was one. Mr. Armstrong is probably mistaken 

 in saying that the valves of the pod open. I have never seen any evidence 

 of this in any of the numerous specimens that have at various time come 

 under my notice. 



19. Note on the Rediscovery of Myosotis (Exarrhena) Lyallii Hook. f. 



This plant has not been collected since Dr. Lyall discovered it in the 

 neighbourhood of Milford Sound, during the cruise of the surveying-ship 

 " Acheron "' in the years 1847-51. Last January, however, Messrs. Crosbv 

 Smith and Cuthbert again collected it on the shingle-faces of Mount Burns, 

 Fiord County, at an altitude of about 5,000 ft. Their plant quite accords 

 with the description of M. Lyallii in the " Flora Novae-Zelandiae." Mv 

 Myosotis oreophila is quite unlike this species, under which Cheeseman 

 has suggested placing- it.

1. Uncinia strictissima- (Kiikenthal) Petrie (ante. p. 55). 



This species was collected in 1890 on the Auckland Islands by Mr. F. R. 

 Chapman (now Mr. Justice Chapman), from whom I have several character- 

 istic specimens. U. rubra Boott. has not as yet been found on our sub- 

 antarctic islands, but their plant population is still too incompletelv known 

 for us to feel sure of its absence. 



2. Uncinia compacta R. Br. 



Mr. B. C. Aston collected some dwarf specimens of this on Campbell 

 Island in January, 1909. They differ from the typical plant as it occurs 

 at elevated stations in New Zealand only in having nearlv sessile flowering- 

 spikes, a condition that is practically present in a form of the species growing 

 a little below the snow-line on the Sealey Range near Mount Cook, of which 

 I collected a number of specimens. 



3. Uncinia australis Pers. var. pedicellata (Kiikenthal) Petrie comb. nov. 



(ante, p. 54). 



Mr. Aston collected this on the Auckland Islands, and contributed 

 several specimens to my collection. 



4. Uncinia Hookeri Boott. 



Kiikenthal and Cheeseman .refer this plant to U. riparia R. Br. This 

 conclusion does not commend itself to me. Mr. Aston most kindly gave
