H. minor, Rumphii, elongata and lycostoma the bracts also are white silky- 

 tomentose over a large area but above the midst and near the edges the 

 hairs present a rather different character being composed and visible with 

 the nude eye. The tomentum is more and more interrupted and consists 

 of separate tufts of stiff silky bushy hairs. In H. elongata they are deflexed 

 and of a peculiar pectinate appearance, in the other species they are round. 



In H. Lycostoma the bracts are silvery white tomentose, (the tomentum 

 composed of hairtufts), over the by far largest part, only the top and upper 

 margin are red and glabrous. In H. minor and H. elongata only the 

 basal part of the bracts is covered with a joined tomentum, for the 

 most part the hair-tufts are separate and the bracts being strongly ribbed, 

 the hair-tufts are placed in irregular longitudinal files, and the surface of 

 the bracts gets a more or less reticulate appearance. In H. Rumphii the 

 longitudinal ribs are very strong and the hair-tufts placed in undulate trans- 

 versal lines, and the edges are densely villous. 



In H. scyphifera, H. Pininga and H. tomentosa Bl. (H. villosa Val.) 

 the outer involucral bracts are rather strongly longitudinally ribbed and in 

 the same time transversally crossed by small corky septs. 



In H. scyphifera the reticulation is very prominent and regular the cross 

 septs being as distinct as the ribs; only in the middle part of the bracts 

 the longitudinal ribs are obsolete and the transverse septs are joining in 

 an irregular and interrupted way, and are covered with a white down. 



In H. Pininga (type and red flowered variety) the bracts are thinly but 

 distinctly longitudinally ribbed and transversely crossed by wide corky septs, 

 almost square and as broad as the interstices between them and in the 

 middle part of the bract, so far extending that the interstices are quite 

 filled up, so here the bract is no longer reticulate but almost even, only 

 with small dispersed pits, only the side and upperparts are distinctly reticulate. 



There is however in this respect some difference between the more 

 common yellow flowering variety and the red-flowering variety. In the 

 former one the bracts are glabrous in the adult state, and the even and 

 smooth area occupiés a large part of the bract, in the red-flowering variety 

 again this even part is very small and the bract is almost wholly reticulate, 

 moreover there are bristly hairs placed in the interstices, making the whole 

 surface somewhat rough and scabrous. In all specimens the edges are 

 densely ciliate. 



In the orange flowered variety (which perhaps should be considered 

 as an apart species) the longitudinal ribbing of the bracts is getting very 

 obscure while the crossing bars are very thick and irregularly confluent but 

 not filling up the insterstices, forming a labyrinthoid net covering the whole 

 b r act, the margins of the meshes are finely puberulous while the interstices 

 between them are conspersed with bristly hairs, making the surface very 

 rough to the touch.
