Andreas Wistuba Posted March 17, 2014 Report Share Posted March 17, 2014 Here are some pictures of a spiny Hydnophytum that I found in the Mc Cluers Gulf of West Papua last year. I was quite puzzled about the spiny caudex but Derrick pointed me to H. forbesii when I first posted a picture of this in the Facebook group late in 2013. I agree that it's not unlikely that it is indeed H. forbesii: From Hydnophytum forbesii Hook. f. Bot. Mag. 118: t. 7218 1892: Link to comment Share on other sites More sharing options...
Frank Posted March 17, 2014 Report Share Posted March 17, 2014 Here is the translation of the Latin description of Hydnophytum forbesii: HYDNOPHYTUM Forbesii – Rhizomatous tuberous lobate prickly, with short cylindrical stems; leaves subsessile, obovate, blunt, at times subacute; axillary flowers with very short pedicels; calyx tube very short, truncated at the mouth ; corolla’s tube elongated, thin, cylindrical, with many long ovate lobes, hairless on the outside; fauces with an external ring; tube is villous on the upper part; short anther filaments, style thin, 2 enclosed stigmas; drupe rhomboid, umbonate; 2 pyrenes obovoid-oblong, compressed at the apex, long-rostrate between the two lobes Link to comment Share on other sites More sharing options...
jeff Posted March 17, 2014 Report Share Posted March 17, 2014 have you a better leaves picture ? it's a shame no corolla picture with the ring hair-anther-stigma position ? ANDREAS I send you a herbarium sheet. H.forbesii seem close to H.mosleyanum it is a HUXLEY reflexion. jeff Link to comment Share on other sites More sharing options...

ANDREAS I send you a herbarium sheet. H.forbesii seem close to H.mosleyanum it is a HUXLEY reflexion. jeff While it's not a closeup I think it's obvious that these are not H. moseleyanum leaves... Another interesting characteristic. Plants form "daughter tubers" from the root system: Link to comment Share on other sites More sharing options...
jeff Posted March 23, 2014 Report Share Posted March 23, 2014 difficult to see . if one day you have the macro corolla ( with the anther-stigma-ring of hair position )may be more easy for a determination ? jeff Link to comment Share on other sites More sharing options...
Derrick Posted October 5, 2014 Report Share Posted October 5, 2014 H. forbesii Hook f. (Sir Joseph Dalton Hooker) in Curtis’s Botanical Magazine #118, tab.7218, (1892) (Bot. Mag.) http://www.biodiversitylibrary.org/item/14246#page/34/mode/1up. Image, http://www.biodiversitylibrary.org/item/14246#page/33/mode/1up . The very first spiny hydnophytum found. Now believed by C. R. Huxley to be part of a cline of forms with tubers becoming very smooth-surfaced as in most Australian examples of H. moseleyanum.
