Jaltomata aspera (R. & P.) Mione

This photo was generously provided by Dr. Graciela Vilcapoma S. and Arturo Granda P. (collection 4326).

 

Herbaceous to suffrutescent. Hairs of leaves not gland-tipped. Pedicels articulated (one can see both a pedicel and a peduncle). Flowers almost always solitary. Corolla rotate-campanulate, 5-lobed, greenish-yellow or yellow-green, lacking 5 pairs of maculae, 42 mm across. Anther Length: 3.5 - 4.5 mm, stamen Length: 12-14 mm. Tough, bowl-shaped layer of tissue (see below) apparently formed by the bases of the stamens. Filaments glabrous. Style widest at base and gradually narrowing toward apex. Stigma no wider than top of style. Nectar red. Fruit Color: orange (Granda 926); white (Macbride 1962)

Left: Note how style is widest at base and gradually narrows toward stigma, and how stigma is no wider than the top of the style. Anthers undehisced. Evident in this photo is the bowl of tissue either formed by bases of stamens or adnate to bases of stamens.

 

 

Lower Left: Anthers. Ventral view on left; dorsal view on right. Units vertically along right are mm.

 

 

Lower Right: two anthers were removed to show the bowl of tissue apparently formed by bases of stamens. At the center of the photo is the ovary of the flower, with the style attached at its top middle.

 

All three of these photos are of collection Mione, Leiva & Yacher 615 after flowers were stored in 70% ethanol for a few years. Photos by Mione.

Geographic Distribution: Peru, Department Lima
In the loma-formation: Elevation 152 to 500 m, flowering Sep, Oct & Nov.
In the Andes: Elevation 1600 - 2290 m, flowering Mar & Apr (and one specimen was flowering in Jan during an El Niño event).

Lima Lima TYPE: Hills of Lima named Amancaes not mentioned in protologue, but we know these hills to be under 500 m from labels of conspecific collections in these hills not mentioned in protologue, but we know that Amancaes is loma-formation "flowering in Oct and Nov" is stated in protologue, so collections were very likely made during these months Ruíz López & Pavón s.n.

Two Jaltomata species are similar, sharing with J. aspera copious colored nectar and a bowl-shaped structure formed by the bases of the stamens.
One grows in La Libertad and its working name is GreenFruit&OrangeNectar. The other species grows in Arequipa and its working name is ArequipaPurple.

In the book "Travels of Ruiz, Pavón and Dombey in Peru and Chile" Jaltomata aspera is mentioned as collected between Huaura and Sayan and Torreblanca or between Torreblanca and Lima (page 107). As best as I can determine, these location are along the coast in the department of Lima.

Local Names

Synonymy:
Jaltomata
aspera (Ruiz & Pavón) Mione. Basionym: Atropa aspera Ruiz and Pavón, Flora Peruviana, et chilensis 2: 45. 1799. Ulticona aspera (Ruiz & Pavón) Raf., Sylva Telluriana 55. 1838. Hebecladus asperus (Ruiz & Pavón) Miers, London J. Bot. 4: 322. 1845.

Saracha
ciliata Miers, Ann. Mag. Nat. Hist., ser. 2, 3: 446. 1849.

Saracha
lacrima-virginis Bitter, Repert. Spec. Nov. Regni Veg. 17: 341. 1921.

Saracha
urbaniana Bitter & Dammer, Repert. Spec. Nov. Regni Veg. 17: 342. 1921. Weberbauer 5262 =5305 according to label on photospecimen at WIS.

Saracha urbaniana could someday be transferred to Jaltomata as J. urbaniana (Bitter & Dammer). The higher elevation specimens would then all go by this name, and the low elevation (lomas) specimens would continue to be known as J. aspera. The low elevation and the high elevation populations flower at different times of the year, and so are reproductively isolated.
