NOTES ON LIMONIUM.* 
By C. E. Saumon, F.L.S. 
T1.—Livontum Neumant (1. humile x vulgare). 
(Puate 466.) 
Dr. L. M. Neuman in 1897 (Bot. Not. 207) pointed out that 
plants ‘evidently to be referred to this hybrid occurred in Denmark, 
but it was not until 1901 that attention was called to it in England. 
In August of that year Revs. E. F. Linton and E. 8. Marshall 
discovered it at Bosham, in West Sussex, and recorded it from 
the 
September, and again in 1908, I was able to spend some hours on 
the salt-marshes near Bosham, and the following notes were then 
put together. 
Both L. humile and te vulgare are frequent here and there for 
many mee gt ¢- and creek-line, but it was only where 
alo he coa 
the two grew thickly sie eb. that the hybrid occurred. Very 
great variety of habit was noticeable in these ee a ere 
the examples now approaching one parent, now 
perfect intermediates were seen, but the rete of the hy btids 
favoured L. humile. 
The hybrids possessed a very i be panicle, its branches, 
often springing from the same point (as in L. vulgare var. hallandi- 
cum), were irregularly recurved or incurved; the spikes were wn- 
equally dense, or the spikelets /oosely in two contiguous rows, or 
with empty bracts interrupting somewhat densely- placed scikolotat ; 
the styles were shorter or longer than the stamens; the fruit was 
ormed here and there, but many of the ovaries were barren and 
shrivel] me: 
From L. humile one may separate L. gota ‘oa I name the 
hybrid) ge its per oe usually branched near the summit, or at 
any rate we rom its base, the shorter, less eee or 
the closer set pe and the individual spikelets being shorter 
The petals, too, were emarginate or entire. From L. vulgare it may 
be distinguished by the brighter pre of calyx and bracts, by 
the longer spikes, often incurved, and the absence of the regular 
distichous imbricate arrangement of spikelets. The calyx varied 
greatly in degree of pilosity, which seemed to be determined by 
repoten 
n has stated (Bot. Not. 1897, 207) that the 
hybrids of Drejer’s collecting may be separated from L. se ag of 
which they possess somewhat the habit, by a less — calyx, bad 
pollen, and more or less dense sub- bilateral spikes. Dr. eon 
tells me that some of these Danish examples exactly matched many of 
the Bosham sph dese a series of which I had sent him for inspection.
