for the most part, dried up past recognition. A Crinum, which I 
detected by the dry foliage, lying flat upon the ground, may prove . 
of interest ; the bulbs were very large, and I am in hopes of those 
I obtained producing flowers during the present summer. 
On the islands in the Straits I certainly expected to meet with a 
more diversified flora than I saw there, and probably on the larger 
islands, could the time have been spared to make a careful botanical 
examination, many new plants would have been brought to our 
knowledge. The prevailing high winds are detrimental to the 
growth of tall, handsome trees, thus no trees of any considerable 
size are met with except in the deep gullies between the hills. 
These trees principally consist of Buchanania Muelleri, Engl.; Seme- 
carpus Anacardium, Linn. ; Erythrina indica; Albizzia procera, 
Benth. ; and Barringtonia racemosa, Gaudich. On the hills and 
other exposed situations were Hucalyptus clavigera, A. Cunn., and 
£. corymbosa, Sm., but the tree most generally met with, and the 
one which seems to thrive best, is Zristania longivalvis, F.v.M. 
This has a bright green foliage and a profusion of yellow butter- 
cup-like blossoms, the petals of which are as fugacious as those of 
the peach. Amongst smaller trees three acacias meet one every- 
where, viz., A. Simsii, A. Cunn., of graceful growth and long nar- 
row leaves and slender flower spikes, A. leptocarpa, A. Cunn, with 
glabrous, long, falcate leaves are of a dark colour, and A. Cun- 
ninghamii, Hook. This seems the commonest of the three, and is 
the hoary-pubescent form of the species. With these also are seen 
trees of Sterculia quadrifida, R.Br., the ‘ Nonda,” Parinarium 
Nonda, F.v.M., and the useful shade trees, Terminalia Catappa, 
Tinn., and 7. platyphylla F.v.M., the first of which is also of 
some value as a fruit and oil producer. Diaplanthera tetraphylla, 
R.Br., which in the scrubs about Rockingham Bay forms one of 
the largest trees, is here quite dwarf, the largest I met with being 
scarcely 20 feet high, but beautifully in flower; the flowers of 
these island trees of this species about equalled those on the 
mainland, but the leaves were scarcely more than a third of the 
size, for I find from an entry in an old note-book that in May, 
1873, I measured leaves of this tree growing on the Herbert River, 
which were 25 inches long and 13 inches broad. The difference in 
size takes place also in the size of the foliage of G'melina macro- 
phylla, Benth., growing at Somerset and Thursday Islands. The 
trees or Jarge shrubs which are found nearest to the mangroves are 
mostly Cochlospermum Gillivrei, Benth., which produces yellow 
flowers of some beauty, but is very scanty of leaves; Jelaleuca 
symphyocarpa, F.v.M.; Hugenia carissoides, F.v.M.; Pemphis 
acidula, Forst. ; Guettarda speciosa, Linn. ; and Premna obtusi- 
folia, R.Br., which has somewhat round large leaves; Clerodendron 
inerme, R.Br. ; and the universal tropical coast tree, Thespesia 
populnea, Corr., which in other countries is made to serve many
