34 were sent to me by Mrs. 3. vfn der Biji early this year, and I 

 at once recognised it as being the long lost ^^. canura, Haw., and 

 also as the plant M^s. Bolus has figured and described as M, Tug- 

 welliae v.'ithout having identified it with the plant Hav/orth descri- 

 bed as I', canum in 1795, and vrhich soon died out of cultivation, 

 and ancears not to have been refound for over 120 years. 



Mrs. Bolus, hov/ever, as mentioned under Punctillaria optata, 

 has wrongly identified a Punctillaria as being M. canum, Haw., which 

 is quite incomprehensible, for the species of Punctillaria have 

 dull, gryeish-gren or brownish-green leaves that are conspicuously- 

 dotted, never "hoaryish" nor yet at all like "stunted toothless 

 leaves of H. caninum." Haworth makes no mention of dots, and he 

 certainly would have done so if they had been present. His descrip- 

 tion is as follows 5 — "Plant apparently stemaiess, ^eaves 2 inches 

 long, crossing each other in pairs, hoaryish (ilw. , whitish), sub- 

 acinac^'form, rather hard to the touch and turgid; triquetrous, com- 

 TDressed, attenuate from the middle downvrards; sharply keeled; keel 

 hunching out tovjards the noint, which is roundish, v/ith a sharp 

 keeled edge. The full-grovm leaves resemble the stunted, toothless 

 leaves of '^^-, caninum exceedingly." This description exactly accords 

 with Bijlia cana, and as I', canum was discovered by i.^sson, v/ho cer- 

 tainly collected in Prince -Albert J^ivision, it may even hove been 

 found by him in the same general locality as that from which I-irs. 

 Tugv/ell^and Mrs. van der Bijl obtained it. 



Mrs. Bolus has nlaced the plant_^under the genus Hereroa, to 

 which it bears no resemblance, -^nd Schxrantes, apparently without 

 bavin*? seen the nlant, first places it in the genus outtadinteria, 

 where 'it does not belong, and after I had already published the genus 

 Bijlia, founded the genus Bolusanthemum for its reception, possibly 

 unaware that there is alreadj'- a well-knov/n genus called Bolusanthus, 

 whith which it would probably be confused. And later, in Die Gar- 

 tenwelt, 1928, p. 644, he appears to want to chop the poor plant in 

 half and cill each half a different species, since he states that 

 the plant I have described is not the same as that "^rs. Bolus has 

 described and figured as !•'. Tugv/elllae, A viev; that no one v/ho has 



the plant is likely to endorse.
