Amorphophallus impressus question

From: <M.van_Dinther at lumc.nl> on 2010.07.18 at 15:22:10(21205) I have recently aquired an Amorphophallus impressus tuber with offsets. It produced a petiole with small hairs on it (see link), which I have not seen with any other species of Amorphophallus that I have in culture. I have looked in the literature to see if this is normal for A.impressus, but could not find any information on this. Can anybody tell me if this is normal? Thanks!

From: Hannon <othonna at gmail.com> on 2010.07.21 at 04:38:34(21211) Maarten, A. impressus is perfectly glabrous (hairless) in my experience, like most species. It will have markings not dissimilar to yours in the juvenile state and sometimes at the base of the petiole but usually the mature petiole is entirely light green. It resembles A. mossambicensis vegetatively. It helps to know the origin of one's plants- where is this from? Mine is from "coastal Tanzania" and was collected by Ernst Specks.

When I first grew them from seed I saw this and was quite surprised as you are, but Wilbert confirmed this was typical. Unfortunately, they stop being hirsute once they get larger. +More Dan Gibsonia, PA Original Message: ----------------- From: M.van_Dinther@lumc.nl Date: Sun, 18 Jul 2010 17:22:10 +0200 To: aroid-l@gizmoworks.com Subject: [Aroid-l] Amorphophallus impressus question I have recently aquired an Amorphophallus impressus tuber with offsets.

From: "Alan Galloway" <alan_galloway at bellsouth.net> on 2010.07.21 at 12:22:54(21215) Maarten, I believe the species you have is Am. maximus, not Am. impressus.

From: Michael Pascall <mickpascall at hotmail.com> on 2010.07.21 at 20:50:29(21219) Looks like Am. maximus to me . I recently flowered one and have noticed these exact hairs on offsets . They vanish as it matures. From same area in Africa . Find it at CarPoint.com.au New, Used, Demo, Dealer or Private? --_c4b9a9ea-9445-46fe-a771-3f64c66ec453_-- HTML +More --==============885770713159604222=

From: <M.van_Dinther at lumc.nl> on 2010.07.22 at 13:28:59(21225) Thanks for all the replies. Unfortunately I do know from which locality this one is. I will just have to be patient and wait till it flowers to be really sure about it’s identity.

From: "Wilbert Hetterscheid" <hetter at xs4all.nl> on 2010.07.25 at 10:51:08(21249) Hi Guys, I have seen a few very young leaves of impressus with hairs. It is a juvenile aspect that is very erratically spread over a few east African species and then within these species. Even the red spots may be nothing more than a juvenile character and disappear with age. That doesn't rule out that the plants are not really impressus but that will only become apparent when they flower.......
