rhizome bo peculiar to that family. Arthropteris has a thin 

 scandent rhizome, and the stipes are jointed, and the pinnre 

 are likewise jointed to the raehis ; the latter have free forked 

 veins, the round Bori being situated on the apex of the lower 

 venule. Indusium small, and soon obliterated. 



A. oeliteeata is a peculiar plant, and one which has led to 

 much discussion ; it has been shifted from one genus to another 

 until one scarcely knows what to call it. This plant may, perhaps, 

 be more familiar to my readers by the name of Lindsrea Lowii, 

 for by this name it has been distributed, but it certainly bears 

 no relationship to that family. It is also to be found in some 

 collections as Polybotrya Lowii, but I am equally doubtful of 

 its proving an acrostichoid Fern at all ; it certainly bears more 

 resemblance to Arthropteris than anything else I have seen. In 

 a cultivated state the fronds of this plant have assumed three 

 distinct forms, but as far as I am aware it has not yet fruited, 

 which is much to be regretted. In the first form the pinnae are 

 developed only on one side of the raehis, they are obtusely 

 lobed and decurrent ; they are ultimately produced on both 

 sides of the raehis, still lobed, and decurrent; after producing 

 a quantity of fronds of this form suddenly the fronds appear 

 with distant, broad, and entire pinna?, somewhat rounded at the 

 base, and acuminate at the apex. In his state the plant lookB 

 very like a Nephrolepis, and I do not anticipate any further 

 alteration in its form, saving the production of sori. Its fronds 

 are bright dark green, and it should make a fine object upon 

 the Btem of a tree Fern, or upon an artificial pillar. I say it 

 should, because I have never been able to make much progress 

 in its cultivation ; the reason I am at a loss to discover, but I 

 shall still endeavour to conquer the difficulty. It has been in- 

 troduced to our gardens from Borneo, but probably may be 

 found throughout the whole of the Indian Archipelago. 



A. tenella. — This plant makes a nice covering for the stem 

 of a tree Fern, its creeping rhizome Boon mounting to a con- 

 siderable height, and fixing itself very firmly. The fronds are 

 pinnate, pinnse entire, oblong acuminate, and dark green. It 

 also rejoices in the name of Polypodium tenellum, P. filipes, 

 and Arthropteris filipes. It succeeds admirably in a cool 

 fernery. Native of New Zealand. — Expekio Ckede.

 divide it into four equal parts, as 1, 2, 3, and 4. With the 



radius 2, 4, which is half the 

 length of the line, draw arc c ; 

 from point 1 draw arc c, as 

 shown by the radius ; also from 

 point 3 draw arc d. 



Fig. 21 is drawn from line 

 A E in the same way as the 

 above figure. Divide the line 

 into four equal parts, as in the 

 preceding case. With the radius 

 1, 3, draw arc c. From point 2, 

 draw arc /. From point 4 draw 

 arc d. 



Fig. 22 is drawn from an equi- 

 lateral triangle. Draw triangle 

 '"' ~ 2- aec. Divide each line into 



I four equal j-nrts, as line A b, as shown by 1, 2, 3, 4. With 

 radius 1, 2, which is one-fourth of the line, draw arc d; with 



radius 3, 2, draw arc c ; 

 and so on with the other 

 sides, and the figure will 

 be complete. 



Fig. 23 is drawn by 

 dividing the sides of the 

 equilateral triangle abc 

 into two equal parts, as 

 shown by 1 and 2. On 

 line a e, from point 1, 

 which is half the line, 

 draw arc d ; from point A 

 draw arc e ; from point E 

 draw arc /; and so on 

 with the other two fides. 

 When the arcs are aE 

 drawn, draw the straight lines between the arcs. — M. O'Donnell,

NOTES MADE DURING A TOUR IN IRELAND. 



No. 2. 

 In the immediate neighbourhood of Dublin there are many 

 fine gardens at the seats of the nobility, government officials, 

 and the wealthy tradesmen. Such gardens are very secluded, 

 so that the passer-by can see little of them ; still, though I 

 believe the Irish people may be very fond of flowers, yet about 

 Dublin the visitor is struck very forcibly with the lack of these 

 in the prettily-kept gardens of the smaller villas and the dwell- 

 ings of the poorer classes about Dublin, in comparison with 

 those round London and other English towns. I wish to see 

 displayed a little more of this popular love and regard for 

 flowers; it would not only enhance the beauties of an already 

 beautiful city, but would give much pleasure to the people 

 generally. The people of Dublin have, however, next to our 

 own royal gardens of Kew, the best botanical garden — viz., 



GLASNEYIN. 

 My first object after my arrival in Dublin was to visit this 

 famed garden, where I was very courteously received by its 

 talented director Dr. Moore. The botanic garden of Glasnevin 

 is naturally very beautiful ; it lies a little to the north of Dublin 

 on the main road leading from Saekville Street through rather 

 a poor low neighbourhood, giving one a rather unfavourable 

 impression of what is to be seen. Once at the gates, however, 

 all this vanishes, and we enter, I should say, one of the prettiest 

 and most interesting public gardens in the world, especially if 

 the visitor has the good fortune to meet Dr. Moore, who is all 

 kindness, and full of much interesting information respecting 

 every plant in the gardens. Here attention is called to a big 

 tree, there to a little Moss, yet the same interest is attached to 

 both. We are told how, when, and by whom each was intro- 

 duced, and all the ups and downs of their chequered lives. To 

 true lovers of plants there is nothing more delightful than this 

 kind of talk, so with Dr. Moore I was at once at home. The 

 garden, which is tolerably extensive, is very diversified in cha- 

 racter, the surface undulating, having many distinct features, 

 and appearing, perhaps, of greater extent than it actually is. 

 No better style of ground could be selected than this for a public 

 garden, yet apart from its natural beauties it is extremely well 

 designed and tastefully laid out, presenting plenty of green 

 trees and green grass, and pretty winding walks. The beauty
