36. Pliyllostachys flexuosa. — Very like the last, but smaller 
and with some well-marked distinctions. 
37. Phyllostachys violescens. — Suffers considerably every 
winter, but grows rampantly again in spring. 
38. Phyllostachys Henonis. — My favourite in the whole group 
for grace and elegance. 
39. Phyllostachys nigra. 
40. Phyllostachys 7iigropimctata. — A variety of the last. 
41. Phyllostachys Boryana. — Also supposed to be a variety 
of nigra, but very distinct. 
42. Phyllostachys Castillonis. — A beautiful variegated 
species. 
43. Phyllostachys Kumasasa ; syn. P. viminalis, Marliac. — A 
■very pretty dwarf. 
Since the above list was drawn up three Indian species — 
Arundinaria racemosa, Arundinaria aristata, and Thamnocala- 
mus (or Arundinaria) sjjathifloriis — have proved perfectly hardy. 
Eliminating Arundinaria falcata and Thamnocalamus Falconeri, 
which are not to be relied upon, we have no less than forty-four 
species of Bamboos which we may reasonably hope to see thrive 
in our pleasure grounds. 
I would call attention to the fact, which I have already 
pointed out in the Garden newspaper, that every one of these 
forty-four varieties has the venation of the leaves tessellated. 
It is remarkable that no Bamboo with striated venation has 
hitherto proved hardy. Witness Arundinaria falcata, Thamno- 
calamtcs Falconeri, and certain of the Japanese and Chinese 
Bamboos with striated leaves which have uniformly proved to 
be failures. I do not, of course, pretend that all Bamboos witli 
tessellated leaves will bo hardy — indeed, we know that that is 
not the case — only that none has so far succeeded that is without 
that qualification. It is a curious coincidence that the only 
hardy Palm, Chamccroi^s e.rcelsa, also has tessellated leaf- veins. 
As regards the geographical distribution of our hardy Bamboos, 
it is to be observed that almost all of them come from China or 
Japan. The Himalayas have so far yielded us only three abso- 
lutely hardy species, Arundinariaracemosa, Arundinaria aristata, 
and Thavmocalamus sjmihiflorus ', the United States of America 
one, Arundiiiaria macrosperma, the typical Arundinaria of 
Michaux. From the Andes we have nothing, unless indeed
