A NEW VARIETY OF YIOLA ODORATA 
S3 
foliage; a change in texture of the stymies from membranous to 
mostly herbaceous; leaves with a longer and broader lamina (5|x 
5 cms., increased to 7x7| cms.) ; petioles with the characteristic 
hairs of hybrids or mutations of V. liirta x odorata to the short 
depressed hairs of V. odorata ; flowers unscented in the first year 
(largest 3| X 2\ eras.), later with a fine scent (largest 2\ X 2\ cms.) ; 
the spur pale in the wild state has become paler (only faintly 
mottled) under cultivation. 
I am indebted to Mr. Spencer Moore for the following diagnosis, 
drawn up from my notes 
Viola odorata L. var. immaculata mihi. 
Varietas ob characteres sequentes distinguenda, nempe petioles 
pedunculosque erectos, stolones longos et validos, slipulas magis 
herbaceas, stolones hornitonos flores et fructus prsebentes (uti non- 
nunquam in speciebus aliis prsesertim in V. alba Besser), flores 
omnimodo alhos (calcar ipsum semper recurvum solummodo dilutis- 
sime maculosum) optime pansos petalisque latioribus gaudentes. 
/ NOTES ON THEACEjE.—II. 
By T. A. Sprague, B.Sc., F.L.S. 
Messrs. Fawcett and Rendle’s “Notes on Jamaican Ternstroe- 
miacece ” (p. 52) raise two general questions : (1) What are the quali¬ 
fications for nomina conservata ? (2) Should the incidence of generic 
names be determined by the type-method or by the method of 
residue ? 
Tiieace^e or Teriystr(emiace^e. 
I do not agree with their suggestion that the name Ternstrce- 
miacece should be conserved. The object of a list of nomina con¬ 
servata was not to reverse name-changes which had met with a large 
measure of acceptance, but to avoid making changes in cases where 
the technically valid name had not }^et obtained as wide currency as 
the other. Exceptions to the Buies are justifiable only when they 
are definitely advantageous. If the two competing names have 
become equally well known, the case for conserving the later one 
fails ; current practice must be taken into account as well as 
historic usage. The name Theaceee is so widely adopted nowadays 
that it seems hardly worth while to suspend the operation of the 
Buies in favour of Ternstroemiacece. It should not be forgotten 
that the conservation on insufficient grounds of numerous generic 
names has been a formidable obstacle to general acceptance of the 
Buies (see Journ. Bot. 1921, 290, 290; 1922, 114, 259). 
Cletera. 
Messrs. Fawcett and Rendle cite Art. 51, 4, as justifying the 
rejection of Cleyera Thunb., “ Everyone should refuse to admit a
