770 DOMATIA IN CERTAIN AUSTRALIAN AND OTHER PLANTS, 



with the principal vein, and are from 2-4 in number. They 

 resemble those of C. lucida externally. 



C. HIRTELLA, Labill. — These resemble the last, but are small. 



C. CUNNINGHAMII, Hook. f. — The clomatia are small but other- 

 wise like those of C. lucida. 



C. SPATHULATA, A. Cunn. — As might be expected from the 

 small size of the leaf, the 2-4 domatia are very minute. 



C. Baueriana, Hook. f. — Dr. Lundstriim, speaking from obser- 

 vation of cultivated plants, says that the domatia in this species 

 are hairless. I find that my notes afford no indication of whether 

 hairs are present in the herbarium specimens I examined. I have 

 simply noted that they resemble those of C. lucida. 



C. GRANDIFLORA, Hook. f. — The domatia are long and the 

 openings slits parallel to the midrib. 



Canthium lucidum. Hook, et Arn. — The pits are situated in the 

 axils of the second pair of veins and the midrib, and rather high 

 up in the forks. They are two in all I have seen, but Mr. E. 

 Betche informs me that they are often entirely absent. The leaf 

 is a very glossy one. The openings are circular, about 1 mm. in 

 diameter, the rim is raised and light-coloured, and vessels occur in 

 it. So far as I can see there are no hairs present. 



C. OLEIFOLIUM, Hook. — The leaf is evidently fleshy, and in the 

 'Handbook of the Flora of N.S.W.' is said to be "scarcely 

 shining." The pouches are situated in the axils of the first and 

 second pairs of veins and midrib, and are slightly alternate; they 

 are 4 in number, but as in the preceding species are not constant. 

 The opening is triangular or circular, and the rim is thickened 

 and contains vessels. No hairs were seen in the interior. 



Randia Moorei, F.V.M.— The domatia in the leaf of this 

 plant are minute. They are in the usual position, and are four 

 or five in number. There is a j)rominence on the upper side of 

 the leaf, and the thickened rim round the orifice on the lower 

 side forms a conical mound, on the summit of which is the small 

 opening. There are no hairs either round the mouth or in the 

 interior. The microscopic structure is rather remarkable. There 

 are : —
