Calceolaria Sinciairii, Hook. If. Plant, t. .JIJI ; Cheescm. Man. N.Z. Fl. 483. 



Calceolaria Sinciairii, as its name denotes, is one of the discoveries of 

 Dr. Andrew Sinclair, who between the years 1841 and 1861 paid special attention 

 to the botany of New Zealand, and formed large collections. Most of these were 

 transmitted to Kew, and constituted no small part of the material upon which 

 Sir J. U. Hooker founded his " Flora Nova? Zelandise " and the later-issued 

 *' Handbook." The first-mentioned publication was in fact dedicated to Mr. Colenso, 

 Dr. Sinclair, and Dr. Lyall, as a " work which owes so much to their indefatigable 

 exertions." 



According to the " Icones Plantarum," in which our plant was first figured and 

 described. Dr. Sinclair collected it in 1842 at "Waihake, in the Northern Island of 

 New Zealand " ; but in the "Flora '" the locality is simply given as the East Cape. By 

 " Waihake " is probably meant Waikaka. near the mouth of the Waiapu River, a 

 district which in those days possessed a large Maori population and a considerable 

 trade. About the same time, or a little later, it was also gathered by Mr. Colenso, 

 both in Hawke's Bay and in the East Cape district. It is now known to extend 

 southwards from Hicks Bay and the East Cape to Hawke's Bay and the eastern 

 base of the Ruahine Mountains. 



Calceolaria Sinciairii is a laxly branched herbaceous or almost suffruticose 

 erect plant 6 in. to 18 in. high, more or less glandular-pubescent in all its parts. It 

 has opposite leaves on long slender petioles, the blade being coarsely doubly serrate, 

 and varying from 1 in. to 3 in. in length. The inflorescence is composed of terminal 

 many-flowered panicles far exceeding the leaves, and the flowers are small, white or 

 yellow spotted with purple, and from ;|:in. to | in. diameter. The corolla is divided 

 into two unequal concave lips, the upper lip being distinctly but slightly smaller, 

 and shallowly 2-lobed ; the under entire or very obscurely 3-lobe(l. 



I have retained the circumscription of Calceolaria adopted in Hooker and 

 Bentham's '" Cenera Plantarum." and in fi^ngler and Prantl's " Pflanzenfamilien " : 

 but Kranzlin, in his monograph prepared for the " Pflanzenreich," has revived the 

 genus Jovellana, which includes both the New Zealand species. It only differs in 

 the two lips of the corolla being nearly equal, whereas in Calceolaria proper the 

 upper lip is much smaller than the other. 



The distribution of Calceolaria is of great interest to the botanical geographer, 

 inasmuch as the genus is found only in South America and New Zealand. But. 

 as is well known, this fact is precisely paralleled by that of Fuchsia. These two 

 genera form by far the most striking proof of a special relationship between the 

 flora of South America and New Zealand.
