484, QUEENSLAND AGRICULTURAL JOURNAL. [1 Noy., 1899. 
Order LILIACEZ. 
NOTHOSCORDUM, Kunth. 
[From nothos, spurious; and scordon, garlic. ] 
(Plate CLI.; 2 segments and 2 filaments have been removed from the figure 
of open flower.) 
Perianth withering, persistent ; segments 6, connate at the base or to the 
middle, the other portion patent or campanulate-connivent, subequal, 1-nerved. 
Stamens 6, fixed to the base of the segments, filaments dilated, subulate at the 
apex. Anthers oblong dorsifexed, dehiscence introrse. Ovary sessile, 3-celled ; 
style filiform, often persistent; stigma small, ovules in cells numerous. Cap- 
sule membranous, 8-dym. or 3-lobed, cells dehiscent. Seeds angular-compressed 
or nearly flat, black. Leaves radical, linear, flat. Scape simple, not leafy. 
Flowers umbellate, not articulate with the pedicels. Involucral bracts 2. The 
garlic scent wanting in the genus.—Benth. and Hook. Gen. Pl. iii. 802. 
N. fragrans, Kunth.; Allium fragrans, Vent. (Bot. Reg. 898.) Flowers 
whitish, with brownish-purple or lilac streak on the outside of each segment, 
- very fragrant. Umbel lax, 6 to 2U-flowered. Leaves all radical, narrow-lorate. 
Scape 1 to 2 ft. high. © t 
Hab. : North America; become naturalised near Bundaberg, J. Keys; and likely to become 
a pest, as besides its bulbs it produces an abundant quantity of seed ; otherwise it is a pretty plant 
for the garden, flowering through the summer months. é 
Order LICHENES. 
The following Lichens have been determined, and the fresh_ species 
described, by the eminent Scotch Lichenologist, Dr. James Stirton, of Glasgow. 
The examples for the most part were collected some years ago by Mr. C. J. 
Gwyther in the neighbourhood of Warwick. The Doctor says— 
“While the collection is a fairly representative one of the Queensland 
Lichen Flora, there are one or two, which show peculiarities of the internal 
organisation of the Ayothecia, that scarcely find a parallel in any that have come 
under my obseryation. 
“As usual, the crustaceous Lecider with fuscous 1-septate spores 
largely prevail, and manifest variations of structure which are very puzzling 
and even perplexing. Such differences I am bound meanwhile to describe. 
The progress of investigations in this section of the Lecidex will doubtless 
serve to elucidate these peculiarities, and to allocate to them their due place in 
classification, as well as to confirm or negative their significance. 
“In the first place there are two species of the genus Co?lema—one of which 
forms part of the present collection, the other is from a former collection of 
lichens sent in 1877 by Mr. Bailey.” 
Collema hypolasium, Strn. Similar to C. reflectans, Nyl., Syn. L. N. Caled. p. 4, 
but obscure, and the epithallus not cellulose, and beneath the thallus densely 
and closely tomentose or velvety. Spores 8, in saccate thece, ellipsoid, simple, 
haloniate, ‘016—:02 x 0075—01 mm.- On bark ; Bailey, No. 30. 
‘The thalline exceple of the apothecium is covered by a cellular layer 
composed of largish round cells, although the upper surface of general thallus 
is non-cellular. 
Collema Gwytheri, Stn. Thallus obscurely olivaceous or nigro-virescent, 
appressed, membraneous, lobate, with ascending lobules, margins somewhat cris 
and crenale ; beneath atmost concolorous and nude. _Apothecia etal 
flat, with a thin entire thalline ring. Spores 8, colourless, almost cylindrical or 
arcuate, 7-10 usually 8-nucleate. Epispore scarcely visible, 025—035 x about 
0083 mm. Hym. with iodine cerulescent. Gonimia concatenate small on 
branches of trees.
