220 DARWIN'S LETTERS TO R. TRIMEN 



to put 2 or 3 flowers of Satyrium or your No. V. or VI. 

 in bottle with spirits and water, and send home by any 

 opportunity. I would then compare your drawings and 

 add some remarks on your authority, if I ever publish 

 again. — But I hope, what will be much better, to see 

 a paper by yourself. 



If you come across Bonatea pray study it — it seems 

 moat extraordinary in description. —

 Dear Sir 



I have thought you would like to see copy enclosed 

 of letter by Prof. Harvey giving names of your two 

 orchids, PI. V. and VI, which were unnamed.' — Now that 

 I hear that in Satyrium the nectaries belong to the true 

 Labellum ; ^ the relation of the parts is to me very 

 puzzling: discs, pollen-masses and stigmatic surface 

 seem all on the wrong side. — If you pursue the subject, 

 I hope you will observe whether there is any relation 



» The copy of W. H. Harvey's letter(dated Feb. 3, 1863,Trin.Coll., 

 Dublin) states concerning the two unnamed forms : ' Both are of 

 the large genus Disa, and I feel confidence in calling them 

 (PI. V) D. harbata and (PI. VI) D. comuta, both common near 

 Capetown.' 



2 The copy of Harvey's letter contains the following account : 

 ' Nectariferous back sepals are quite frequent among Cape Orchids— 

 and correspondently depauperated labella. The labellum is often 

 a mere little tongue [sketch] — sometimes a mere thread [sketch] — 

 and sometimes as in Browrileia, nearly disappears altogether, and 

 is adnate to the column.' 



' In Satyrium the two spurred affair is a ti~ue labellum — the sepals 

 and petals small and crowded together at ih.e front of flower — the 

 opposite to Disa.'
