Recently *Celastrus paniculatus* (Jyotishmati) was mentioned by somebody as one of the Patri's offered to Lord Ganesha. Somehow this plant doesn't figure in the list provided below. Of course there are variations in the literature.

Here is my list of the 21 patris used in Ganesh puja. As ... mentioned there are variations not only in the sanskrit names of the plants but also in the identification of the plants based on the sanskrit names. However, all the plants are medicinally very important.
1. Machi - Artemisia nilagirica, Asteraceae
2. Bhruhati - Solanum indicum, Solanaceae
3. Bilva - Aegle marmelos, Rutaceae
4. Durvayugma - Cyanodon dactylon, Poaceae
5. Dhatura - Datura metel/ D. stromonium, Solanaceae
6. Badari - Ziziphus mauritiana, Rhamnaceae
7. Apamarga - Achyranthes aspera, Amaranthaceae
8. Tulasi - Ocimum tenuiflorum, Lamiaceae
9. Vishnu kranta - Evolvulus alsinoides, Convolvulaceae
10. Dadima - Punica granatum, Punicaceae
11. Devadaru - Cedrus deodara, Pinaceae (Gymnosperm)
12. Maruvam /Marva - Origanum majorana/ O.vulgare, Lamiaceae
13. Sindhuvara - Vitex negundo, Verbenaceae
14 Jaji/Jati - Jasminum auriculatum, Oleaceae; some identify it as Myristica fragrans (Jai), Myristicaceae
15. Shami - Prosopis cineraria, Mimosaceae
16. Ashwadha/ashvattha - Ficus religiosa, Moraceae
17. Arjuna - Terminalia arjuna, Combretaceae
18. Arka - Calotropis procera, Asclepiadaceae
19. Choota - Mangifera indica, Anacardiaceae
20. Karaveera - Nerium oleander/ Thevetia peruviana, Apocynaceae
21. Gandaki - Sterculia urens, Sterculiaceae

Four more names were added to the list in Bhavishya purana -
Bringaraja - Eclipta alba, Asteraceae
Malati/madhavilata - Hiptage benghalensis, Malpighiaceae
Ketaki - Pandanus oderatissimus, Pandanaceae and
Agasthya - Sesbania grandiflora, Papilionaceae

What puzzled me is the inclusion of a gymnosperm - devadaru (Cedrus) in the list which is not easily available. But a search in the internet yielded this information :
Forests full of Devadaru trees were the favorite abode or living place of ancient Indian sages and their families who were devoted to Hindu god Shiva. To please Lord Shiva, the sages used to perform very difficult tapasya (meditation) in deodar forests. There is regular mention of Darukavana, meaning a forest of deodars, as a sacred place in the ancient Hindu epics and Shaivite texts.
