Thorns at anubiases

From: dloginov at ineos.ac.ru on 2009.02.10 at 12:28:29(19072) Recently I have found small thorns (1-2 mm) at some plants of genus Anubias. Thorns settle down on petioles of leaves. What role thorns play at anubiases? Also it would be interesting to communicate to other fans of anubiases and to receive representation about their collections of these Aroids.

I have grown several species of Anubias but never seen anythorns. Do you have any pictures you could share?

From: Peter Boyce <phymatarum at googlemail.com> on 2009.02.12 at 23:42:52(19094) Dmitry, Are these thorns associated with the stem adjacent to the leaf or are they part of actual leaf (petiole, petiolar sheath, etc.) My suspicion is that they either are epidermal outgrowths (i.e., prickles) of the sort often associated with the lasioids or perhaps toughened roots (so-called root-thorns) that occur in some aroids (notably Pothos and Phymatarum).

From: dloginov at ineos.ac.ru on 2009.02.14 at 18:02:26(19106) Hello, Thanks for your attention to this problem. I with my colleague Sergey Gerasimov (from Ukraine) looked the thorns at following species: A. afzelii, A. gilletii, A. heterophylla, Anubias ‘Frazeri’ and A. barteri var. caladiifolia ‘Variegated’. These thorns are part of actual leaf, namely petiole, as epidermal outgrowths. The photo of petiole of A. heterophylla is attached.

From: Peter Boyce <phymatarum at googlemail.com> on 2009.02.16 at 06:52:58(19111) Ah, these are prickles. Prickly petioles are well known in the lasioids but also occur in Nephthytis and also Anubias. There role is completely obscure.

From: dloginov at ineos.ac.ru on 2009.02.18 at 12:19:03(19121) Dear Peter, This error in terms is probably caused by features of transfer between Russian and English. In Russian such epidermal outgrowths are called as thorns. Indeed, I found in the literature that J. Bogner named them as prickles, but he does not write about their role. I have only few knowledge about others Aroids. Therefore, could You tell me about a role of such prickles in Anubias?

From: Peter Boyce <phymatarum at googlemail.com> on 2009.02.20 at 06:36:19(19127) Dear Dmitry, As I mentioned in my last email, we are really not all aware of what role such prickles might play in the aroids. As Tom has also mentioned they occur in Neotropical Homalomena too. The definition of a thorn is an indeterminate structure (such as a stem or root) capable of lateral growth through branching (and even of flowering and bearing leaves in some instances, that have a protective role. Thorns are most commonly found in Rosaceae (e.g., Crataegus), Fabaceae (notably Gleditschia) and Rhamnaceae (many genera).

From: Peter Boyce <phymatarum at googlemail.com> on 2009.02.22 at 00:38:58(19131) Hi Marek, There are species in the genus Homalomena in the Neotropics, but whether they BELONG in the genus is far from conclusive. A recent molecular study seemed to show that the Neotropical species are embedded in Philodendron, but work we are doing here suggests that the situation is rather more complex and that there may well be several genera involved.
