HYBRIDS AMONG THE AMARYLLIZZ AND CACTACE, 409 
P. anguliger, Ackermanni, grandis, latifrons, phyllanthoides, strictus, 
crenatus, and Hookeri are good species. 
Laboret listed thirteen hybrids as “ known by the Catalogues,” * but 
which were, apparently, only names to him. Of the twenty-three alleged 
hybrids between Cereus (of the section to which C. grandiflorus belongs) 
and various Phyllocacti, one at least (C.latifrons) has been since admitted 
asa species. Yet this does not disprove the allegation that it was also 
raised by hybridisation, for the crossing of extreme forms is sure to pro- 
duce a mean, just as the cross between Crinum pedunculatum and 
C. zeylanicum (Bury, Hex. 80) produced a plant indistinguishable from 
C. amabile [C. augustum]. 
EXPLANATION oF TABLES. Pace 410. 
Under “ Reversion” are tabulated all instances in which some (often supposititious) 
ancestral character reappears, or in which the characters of other species appear. 
The appearance of characters unknown in either parent and not traceable in any 
(presumed) ancestral or collateral species has been tabulated under “ Reversions not 
traceable to either,” although some might argue that such were something new. 
Fractions have been made use of in cases in which it was impossible to decide the 
category; for instance, hybrid Cacti which bore two-sided and three-sided stems on 
the same plant would appear in each category as 3. 
A refers to all divergent characters, viz. those which are dissimilar in the parents 
inter se. These are usually equipoised in hybrid offspring, but occasionally an odd 
plant may show dominance of one parent. 
B refers to the colowr of the perianth (and of stigma in Cacti). 
C refers to the form (shape) of the perianth. 
D to colowr-markings on the perianth. 
E to foliage (stems in Cacti). 
F to rootstock. 
G to habit of entire plant. 
H, to time of expansion of flowers (whether day- or night-flowering). 
H, to the carrying of terminal flower-buds in addition to those that are axillary. 
J to the fragrance of the flowers. 
K to the carrying of aérial in addition to terrestrial roots. 
HYBRIDS AMONG THE AMARYLLI® 
(Excluding Narcissus, Galanthus, and other hardy genera). 
I dealt very fully with these in the “ Gardeners’ Chronicle” of January 
and February 1901, when I gave a list of 27 hybrids. Since then some 
more have been notified. | 
As Elisena and Ismene, Cyrtanthus and Vallota, Hucharis and Urceo- 
lina, and (probably) Brunsvigia and Amaryllis have been reconciled, it 
will be difficult in future to support the contention of so many genera as 
have been admitted by some authors. 
Among hybrids raised by myself are the following :— 
1. Crinum scabrum x C. Moorei = C. Worsleyi (W. Watson in 
“Gard. Chron.’ Feb. 2, 1901). A beautiful plant, equipoised between 
its parents. Sterile. 
2. Crinum gigantewum x C. amabile=C. amanteum. Fairly equi- 
poised, but inferior in beauty to either parent. Probably sterile. 
* Besides those noted in the above list of hybrids as known to him.
