Hydnocarpus pentandra:
After a lull of a short period,  there is another very pleasant wave of flowering of trees of Rani Bagh, Mumbai. Sharing some pictures of Hydnocarpus pendandra from Flacourtiaceae family.

---

– the first pic shows the female flower and 5 stigmas (pentandra) on top of the ovary. The second pic shows a mature female flower with just the ovary, the fruit is usually 5 cm, globose, hard and woody.

Hydnocarpus ¿ pentandra OR pentandrus ?:
Would like to know the reasoning for both spellings being used: Hydnocarpus pentandra AND Hydnocarpus pentandrus.

    Sites like NPGS / GRIN, The Plants List maintain Hydnocarpus pentandrus.
Am sure, .. and .. have given a thought too, to this discrepancy and have reasoned to keep Hydnocarpus pentandra in their notes

---

.. nomenclature is a debatable subject, I am not competant to make any comments on preferences, I just follow what BSI says.

---

Me too agree with you, .. … this subject could be as deep as Mariana’s Trench !! Would go with pentandra … faintly remember, ..  having told me that the trees are associated with male form of the epithet, hopefully not mistaking.

---

The end depicts the gender.
But gender in ICBN is very technical.
A tree is male, but if it has been given a feminine generic name then it is to be followed. In other words, even if a name ends with a masculine suffix, it will be considered as male even if it is not !!! It is so confusing all the time.

    Ideally the name should be Hydnocarpus pentandrus but interestingly in the original description it is written as Hydnocarpus pentandra (Buch.-Ham.) Oken Allg. Naturgesch. iii. (2) 1381 (1841) which is attached with the mail.
Basionym: Chilmoria pentandra Buch.-Ham. Trans. Linn. Soc. London 13(2): 501. (1822)
Hamilton’s protologue was unfortunately not free.
Article 62.1 of ICBN, Vienna code says: “62.1. A generic name retains the gender assigned by botanical tradition, irrespective of classical usage or the author’s original usage. A generic name without a botanical tradition retains the gender assigned by its author.”….. SEE ITS SO CONFUSING. It means, Pankaj Kumar is a girl if his dad says so :P….. but he is a boy if his dad doesnt say anything or he is a boy if his dad says so….
First step if to see what the original basionym was? In this case it was “pentandra” but at the same time, original generic name was also “Chilmoria”, obviously both with the same gender.
Recommendation 62A, of ICBN, Vienna code says: “62A.1. When a genus is divided into two or more genera, the gender of the new generic name or names should be that of the generic name that is retained.” hence the new name Hydnocarpus should have been used with pentandrus, but this was not the case.

    Article 61.1 of ICBN, Vienna Code says: “Only one orthographical variant of any one name is treated as validly published: the form that appears in the original publication, except as provided in Art. 60 (typographical or orthographical errors and standardizations), Art. 14.11 (conserved spellings), and Art. 32.7 (inproper Latin
terminations).”
Article 60.1 of ICBN, Vienna Code says: “The original spelling of a name or epithet is to be retained, except for the correction of typographical or orthographical errors and the standardizations imposed by Art. 60.5 (u/v or i/j used interchangeably), 60.6 (diacritical signs and ligatures), 60.8 (compounding forms), 60.9 (hyphens), 60.10 (apostrophes), 60.11 (terminations; see also Art. 32.7), and 60.12 (fungal epithets).”.
    Hence, when you transfer it to new genus it was supposed to retain the gender of generic name as “Hydnocarpus pentandrus” but this didnt happen according to the protologue where it is mentioned as
“pentandra”. So this name should be retained, according to me and it should be Hydnocarpus pentandra unless it was corrected by some one according to another article 32.7 of ICBN Vienna Code, that says, “Names or epithets published with an improper Latin termination but otherwise in accordance with this Code are regarded as validly published; they are to be changed to accord with Art. 16, 17, 18, 19, 21, 23, and 24, without change of the author citation or date of publication (see also Art. 60.11)”.
Hope this is understandable.
Unfortunately I dont know what is Mariana’s Trench !! 😛

Many thanks dear .. for the elaborate explanation regarding pentandrus and pentandra of Hydnocarpus.
Going with Hydnocarpus pentandra.

    About Mariana’s Trench …
Just as we know peak of Mt Everest is the highest place above sea level, so is Marian’s Trench lowest below sea level. More at http://en.wikipedia.org/wiki/Mariana_Trench.
To me the depth of subject discussed is analogous to that of Mariane’s Trench.

---

If you or anyone else are writing a scientific article on this plant then in accordance with Article 32.7 of ICBN Vienna Code you can change the spelling without changing the author citation or date of publication.
