CUNNINGHAMIA. 
A genus founded by Robert Brown in 1826 upon a solitary 
Chinese species. The synonym Belis of Salisbury is earlier, 
Trans. Linn. Soe. viii. p. 315 (1807), and strictly should have 
precedence, but, owing to the similarity with Bellis, it has 
never been taken up, and it would be productive of unnecessary 
confusion to adopt it now. A still earlier name is Pinus 
lanceolata. 
The lanceolate leaves are spirally arranged and uniform, the 
male flowers in terminal umbellate spikes. The anther-crest is 
serrulate, bearing three free pendulous anther-lobes. The 
female cones are aggregated or solitary on the ends of the 
branches ; the bracts spirally arranged, wholly confluent with the 
seed-scale, which is reduced to a mere cellular projection, with 
no vascular connection between the central bundle of the bract, 
at least in the first instance. From this placental process hang 
three compressed seeds, each with a membranous wing. The 
attachment of the seed to the placental process or “ lamina 
ovulifera” is very like what happens in the macrospore of Isoétes. 
The anatomical conformation of the bract is essentially the 
same as in Conifers generally ; and as the bracts are in contin- 
uous series with the leaves, the cones of Cunninghamia, like 
those of Agathis and of Araucaria, are mainly composed of bracts, 
the true fruit-scale being reduced to a minimum (see Dickson, 
Edinburgh New Philosoph. Journal, vol. xiv. pt. 4, 1861). In 
the leaves of Cunninghamia there is well-marked palisade- 
tissue, but in the bracts this is replaced by ordinary parenchyma 
traversed by five resin-canals. The structure of the placental — 
outgrowth seems to be exclusively cellular, at least for a con- 
siderable period. 
AGATHIS. 
Rumphius’s name of Dammara has, as pointed out by Bentham, 
no real claim to precedence, hence Salisbury’s name of Agathis 
(1807) is the one adopted in the ‘Genera Plantarum.’ The species 
are lofty trees with thick leaves spirally arranged. The male 
flowers are catkin-like, sessile or stipitate, axillary or super- 
axillary. The stamens are placed in a spiral series continuous
