229 general resemblance to Punctillaria cortire.cte (except that the 



tils of the leaves curve upwards instead or recurve and are more 

 compressed), I think it best to call attention to it here. 



Mesembryanthemum carina ns, ^aw. , ^ev. '^1. 3ucc., p. 90 (l821 ) 

 Plant stemless, forming clumps and having somev/hat the general 

 aspect of Punctillaria compacta, but v;ith the leaves compressed 

 and dilated at the keel near the apex. Leaves apparently 3-4 pairs 

 to a grovrth , at first ascending, becoming v.ddely spreading end 

 curved upwards at the tips, lS-3-i^ inches long, 4-7 lines broad at 

 the very base, but rather abruptly contracted to 3-4^ lines broad 

 a little above the base, thence with the upper side gradually tap- 

 ering to an acute aT>ex, semi-terete and 3-4 lines thick at the 

 basal part, comnressed and dilated at the keel of one leaf of each 

 rair scarcely or not at ell dilated there and acute in side view, 

 flat or faintly concave on the upr>er side, rounded on the back at 

 the base, keeled at the upner part; surface glabrous, slightly 

 rough, glaucous-green, covered with numerous, conspicuous, slight- 

 ly prominent darker green dots, which the artist seems to have 

 indicated as being more prominent on the keel or that the keel is 

 somewi^.at scabrid. Flowers unknovm.

The above is all the information that can be at present be 

 given concerning this plant.

12 As a delay has been caused in the continuation of my account 

 o"** this group by the went of sunshine experienced this year, de- 

 laying the flov/ering of some new species that I wish to include 

 under the genus Giottiphyllum, which follows next in the seouence, 

 and which ere only now flowering, I take the opportunity to pub- 

 lish below a key to some new genera, and descriptions of new 

 species belonging to the genera ^onophytum, Lithops, etc., already 

 dealt with. Most of them have not yeat flowered in this country, 

 but as the size, shape, surface and coloration of the growths are 

 the principal characters that distinguish many of these peculiar 

 plants, and as name? for them ere v;anted in South -Africa also for 

 many that will soon be distributed by Monsieur ^t. ^e ^ekt, ^ have 

 deemed it advisable not to v/ait until they all flower before describ- 

 ing them, proposing to publish descriptions of their flov/ers at a 

 future time; meanwhile the names can be used. 



Also I would like to correct an error to the key to the genera 

 published in The Gardeners' Chronicle 1925, Vol. IXvVIII, p. 433, 

 where the genus ^onicosia (see under the coupled paragraphs ^'os. 27 

 and 28 ) is stated to have alternate leaves. Haworth stated this to 

 be the case. After having examined living- adult plants, I came to 

 the same conclijsion, and therefore accepted this view for the pur- 

 pose of my key, but having this year raised a few plants of this 

 very distinct genus from seeds and wetched their development, I 

 find to my surprise that the leaves are really all opposite, although 

 by a peculiar mode of growth as the plant develops they point all 

 ways end form a large, dence tuft in v/hich they appear to be arran- 

 ged alternately and are very long.
