shortest nectary is found in H. minor and H. lycostoma where it is about 

 as tall as it is broad (a few mm.), and divided by longitudinal incisions 

 into oblong-conical lobes of different length, connected at the base. In H. 

 Lycostoma there are about 5, in H. minor about 8 of these lobes. In H. 

 alliacea there are two broadly linear attenuate stylodes connected at the 

 base at one side and surrounding the style-base, quite free at the other 

 side, both stylodes or only one are bifid at the top and together they form 

 a 4- or 3-dentate cylindric, at one side open tube. 



in H. mollis there are 3 flat linear obtuse stylodes about 7 mm. long 

 connected at the base forming an open cylinder. 



In H. elongata the stylodes are a little longer, and mostly only one 

 at either side. ïn H cyathifera there are two short fleshy bodies forming 

 a short semilunar tube and a third very small lobe. In H. Rumphii they 

 resemble H. minor, and not those of H. elongata, which for the rest is 

 much more like it. 



In the Scyphifera-group the stylodes are connected into a cylindric tube, 

 sometimes very long (va var specimens of H. scyphifera 16 mm. long, in 

 H. Pininga 12 mm., in H. paludosa 7 mm. long), in H. scyph if 'era there 

 are two opposite incisions at the top, indicating the origin from two separate 

 stylodes, in H- Pininga the tube is absolutely entire with a truncate top. In 

 H. villosa the stylodes are lanceolate, connate at the base at one side, quite 

 separate at the other one, about 7 mm. long, In //. rubra there are two 

 free subutate-oblong 3 mm. long stylodes. 



9. Fruit. The fruit as already suggested by SCHUMANN is rather uni- 

 form in the species of Hornstedtia (though only a few of them were known 

 to Schumann) and procured him an argument for the separation of this 

 group from the other groups of Amomum. (ENGL. Jahrb. 27 (1 899) I.e. 402). 



It is always smooth (without protuberances of any kind), either cover- 

 ed with long appressed silky hairs, or glabrous (H. Pininga, H. villosa etc.) 

 with a rather thin but very tough coriaceous, in old fruits woody-fibrous, 

 pericarp, inwardly lined by a soft white membrane, which partly adheres 

 to the septs when the outer skin is loosened. The fruits are not dehiscent 

 but burst in. an irregular way at their base. The seeds are smooth black 

 polyangular and enveloped by a thinly membranous saccate arillus often 

 pulpous in the ripe fruits. 



The shape of the fruit is oblong, obovate, lenticular etc. laterally com- 

 pressed in various ways by their accumulation and growth within the rather 

 firm persistent involucrum; the agreeably acid and often aromatic pulp of 

 -the seeds is eaten by natives, squirrels and musangs ( [Paradox ur us). 



10. Pollination. All species of Hornstedtia are commonly fruiting 

 abundantly, and in open flowers the mouth of the stigma is mostly found 

 filled up by a lump of pollen, which is often germinating and interwoven 

 by pollentubes. How it has been conveyed there can only be stated hypo- 

 thetically, for insect visits never have been observed. In all flowers there is 

 an abundant stock of nectar contained in the tube and in some species
